Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

How Does Plagiarism Checker Work?

  • If you already have a completed text, all you need is just to copy-paste the whole thing in the special box of the chosen plagiarism tool or website, choose suitable settings (if any), then press “check for plagiarism”. It is quite simple and takes just a few moments.
  • Once you have pressed “check for plagiarism”, the system will analyze your text and compare it with different sources to find similarities. As a rule, the duration depends on the text’s length. A standard free online plagiarism checker with percentage can give you the result within five minutes or less.
  • When the system finishes the work you will be transmitted to the reporting page – it contains the comprehensive report on your work, a percentage of its uniqueness, and a list of sources on which similarities were detected. Often, such tools also highlight the overlaps that were found.

As you can see, it is simple. However, for the best and reliable result you have to be careful. There are tons of programs and online tools that can be used but keep in mind that many of them work differently and not all are good for you. To be confident in the truthfulness of the received result, you need to select the best plagiarism checker because only a professional and high-quality software can detect all similarities and give you a reasoned assessment.

The plagiarism tools in this research are tested using 4 test documents , ranging from unedited to heavily edited.

Each test document consisted of plagiarized sections from 140 sources like Wikipedia articles, news articles, open-access journal articles, websites, theses and dissertations, and PDFs.

This setup allowed us to analyze:

  • The reliability of plagiarism checker tools, even when texts are edited to varying degrees
  • The depth and breadth of the tools’ content databases (whether they only covered websites or also journal articles)

We found that free tools were frequently misleading in their advertising and were lacking in many ways compared to paid ones. Our research led to these conclusions:

Free tools Paid tools Scribbr

Able to find full matches?
Pricing Often misleading: only a trial, or not free at all Confusing subscription plans Transparent one-time payment per check

best plagiarism checker scribbr

  • Offers a limited free version
  • Finds far more plagiarism than other tools
  • Detects plagiarism even in edited texts
  • Won’t store or sell your documents
  • Money-back happiness guarantee, with live support available
  • Self-Plagiarism Checker feature allows you to check for self-plagiarism
  • You need to go premium to find out your precise similarity score and view the entire report

Scribbr offers a limited free version that’s perfect for checking if your paper contains potential plagiarism. To view the full report, you need to buy the premium version, which costs between $19.95 and $39.95 depending on the word count. There’s no word limit, so you can upload as big a document as you want.

Quality of matches

Scribbr’s checker, developed in partnership with Turnitin, heavily outperformed all free and paid tools in terms of the amount of plagiarism detected: 83% vs. an average of 42% across free tools.

It performed particularly well with source types relevant to students, such as journal articles and dissertations. Importantly, Scribbr was far more successful than other tools at detecting plagiarism in heavily edited texts, showing it has no trouble with paraphrasing plagiarism.

Scribbr could also consistently provide full matches instead of partial ones, matching the whole plagiarized passage to the correct source.

You see your results in a straightforward downloadable report. Different sources are highlighted in different colors, making it more readable.

The issues identified can be fixed with Scribbr’s Citation Generator , generating correctly formatted citations wherever they are needed.

In addition, Scribbr offers a Self-Plagiarism Checker . This unique tool allows users to upload their own unpublished documents in addition to the public database, to detect any possible self-plagiarism.

However, you can’t edit your text directly in the tool, and it’s not possible to re-check your document for free.

Trustworthiness

Scribbr will not store, sell, or share your uploaded documents. Data is automatically deleted after 30 days, or students can opt to manually delete their document after the check.

Live customer support is offered in multiple languages to assist users. A guide and other resources explaining plagiarism issues are easily accessible.

Scribbr also has a happiness guarantee: if you’re not satisfied with the tool for any reason, you can ask for a new check or a refund.

que text

  • Built-in citation assistant helps to add missing citations
  • Documents not stored in database
  • Support options available (but no live support)
  • Finds partial matches
  • Not clear how the free trial works
  • Monthly subscription of at least $8.25 after free trial
  • Not effective for scholarly sources
  • Doesn’t detect all plagiarism

Quetext offers a free trial of 500 words, after which users must pay for a premium plan.

Additionally, uploading files to Quetext is a Pro feature. If you don’t pay, you’ll have to copy-paste the text from your document instead.

The paid version costs at least $8.25 per month (more expensive plans are available), which allows you to check up to 100,000 words.

Quetext detects more plagiarism (49% on average) than any free tool, but it’s unable to match each source text fully to a single source. Different sentences are attributed to different sources.

While Quetext claims to check against academic sources, we found it didn’t perform well at identifying plagiarism from sources such as journal articles and student dissertations.

Quetext’s plagiarism report is relatively straightforward to understand and provides a useful overview. A precise percentage is shown, with similarities in the text highlighted.

However, different sources are not highlighted in different colors, making the report somewhat difficult to read. Instead, orange highlighting is used for partial matches, red for full matches.

There’s also a built-in citation assistant that can help you fix plagiarism by adding citations. Unfortunately, it’s not very robust. Citations generated this way may not be accurate, and you have to add a lot of information manually.

Quetext states that it doesn’t save your text to a database and that all text submitted remains private and encrypted.

Information about the service is available in the form of FAQs on the website, and it’s also possible to contact the company by submitting a request form.

Check out Quetext

Duplichecker_Screenshot

  • Free (1,000 words per scan)
  • Doesn’t save uploaded documents
  • Relatively user-friendly reports
  • Distracting ads for other services
  • Low level of plagiarism detected
  • Performs very poorly with edited text
  • No color coding for different sources

DupliChecker’s service is free, though you can only upload 1,000 words at a time. If you go for one of their premium plans, you can go up to 25,000.

If you do want to upgrade, a large number of different premium plans are offered on the site, which can be somewhat confusing to navigate. The cheapest is $10 a month.

The level of plagiarism detected by DupliChecker was relatively low (44%).

While the tool was able to find some plagiarism, it was unable to find any full matches. Overall, it performed about as well as other checkers like Small SEO Tools.

DupliChecker’s website is unfortunately full of ads for their other services and for similar sites. A distracting animated “Make it unique” button appears in the report, advertising their rewriting tool.

In the online report, all plagiarized text is highlighted in one color, and it is difficult to figure out what source each source block is matched with.

The site claims not to save uploaded documents, and it deletes content after the check is complete to avoid data leakage. No live support is available, but there is a contact form on the website.

Check out DupliChecker

SmallSEOTools

  • Various options for document uploads
  • Page is slow, somewhat confusing, and full of ads
  • Scans individual sentences rather than full texts

Small SEO Tools is free to use, although you can only check 1,000 words at a time without paying.

You can run multiple checks if you need to scan more than that, although the site requires you to complete CAPTCHAs to upload multiple documents.

Small SEO Tools was unable to identify most plagiarism in our test documents, with an average of only 44%. Since it scans individual sentences separately, it was only ever able to produce partial matches.

Plagiarized text is highlighted (though all in one color), and you can click on it to be shown the source it was matched with.

The page is cluttered with a lot of ads that you can easily confuse with the buttons you need to press.

The report itself is relatively clear. While plagiarized text is highlighted in one color, the tool clearly links matched text with the source identified for it.

Small SEO Tools claims not to store your content after checking it. You don’t have to register to use the tool. Users can also contact a support email to request their personal data be erased.

Check out Small SEO Tools

prepost

  • 1,000-word upload limit
  • Color-coded highlighting
  • Some full matches
  • Citation assistant
  • Live support option
  • Detects a low proportion of plagiarism
  • Report is hard to read
  • Messy, ad-heavy page design
  • Color coding doesn’t distinguish between different sources

It’s unclear whether Pre Post SEO is actually a free tool. While the website claims there’s a search query limit for visitors, the limit is not clearly specified and did not seem to apply when we tested our documents.

You can only scan up to 1,000 words per search and cannot see a complete list of matched sources (instead, you must check them manually). These limits are removed if you sign up for their premium plan, which costs $10 to $45 a month.

Pre Post SEO did find the occasional full match, but in most cases it was only able to find partial matches, like most free checkers. Overall, it performed about as well as tools like DupliChecker and Small SEO Tools.

The page where the checker is hosted is full of distracting and irrelevant ads, making the user experience frustrating.

A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool’s judgment was often wrong. Other than that, the same color was used for different sources, which made the report hard to read.

Pre Post SEO states that it does not store or sell your documents. There is a live support option on the site and a form you can use to request support.

Check out Pre Post SEO

grammarly

  • Language and citation assistant available
  • Does not sell or share documents with third parties
  • Finds a relatively low percentage of plagiarism
  • Same colors used for different sources

Despite the way it’s advertised, Grammarly’s checker is not free. All you can do is see a screen that tells you there’s plagiarism in your text without giving you any details of where it is, how much of it there is, or what the sources are.

After this you’ll be directed to download the Grammarly app and subscribe to their premium service ($30 per month). There’s a limit of 100,000 characters (about 20,000 words) even after paying.

Grammarly was able to find more full matches than most free tools. However, it performed particularly poorly with academic sources and received a low percentage overall, scoring a total of 40%.

As a premium service, Grammarly has a clearer and more visually appealing style than most free checkers. The original formatting of the document remains mostly intact, but the tool uses the same color for all sources, making the results hard to parse.

The subscription also gets you a language and style tool and a citation assistant.

Grammarly does not store, sell, or share documents with third parties.

The site provides a support page with tips, tutorials, and FAQs, and you can submit a question via a form. Live support is not available.

plag detector

  • Free to use (1,000-word limit)
  • Does not store or sell your document
  • Technical issues with long documents
  • Difficult to match text with sources in the report
  • Different sources highlighted in the same color

Plagiarism Detector is free to use and users do not need to register. However, there is a limit of 1,000 words per document. By paying, you can raise this limit to 25,000 words per document.

Plagiarism Detector’s performed about as well as other 100% free tools (40%).

The tool was mostly only able to find partial matches, attributing individual sentences to one or more sources.

Plagiarism Detector’s reports are somewhat difficult to read. The same colors are used for different sources, and hovering over a plagiarized section doesn’t show you the source. Instead, you need to find it in a separate list.

Plagiarism Detector states that it will not store or sell your documents. No live support is available, but there is a help request form.

Check out Plagiarism Detector

Check Plagiarism

  • Offers a citation generator
  • Difficult to match text with sources in the downloadable report
  • Scans sentence by sentence —rarely gets a full match

It’s unclear whether Check-plagiarism.com is actually free. The site describes the free upload limit in a confusing way, allowing you a certain number of “queries” (sentences) per month. However, these limits are not clearly specified and did not seem to apply when we tested our documents.

Check-plagiarism.com performed slightly worse than most 100% free tools, scoring a total of 39%.

While the tool was able to find some full matches, it mostly found partial matches.

The same color was used for different sources, which made the report hard to read. A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool was often wrong.

You can check up to 1,000 words at once for free. 

In the downloadable report, the format of the text is mostly retained. The report provides a long list of sources that are difficult to cross-reference with the text above.

The version of the report shown on the site itself is slightly better, as a box next to the plagiarized text allows you to see the text identified as the source. There is a “rewrite” function, along with a (manual) citation tool.

Check-plagiarism.com claims that the reports generated on their site are “highly secured and un-accessible.”

There are some FAQs listed on the site, but the answers provided are not very clear. They have live messaging support along with a contact form.

Check out Check-plagiarism.com

SearchEngineReports

  • Genuinely free for most purposes (1,000-word upload limit)
  • Lots of distracting ads
  • Unable to find most of the plagiarism
  • Same highlight colors for different sources

Search Engine Reports is free to use, and users do not need to register. However, there is a limit of 1,000 words per scan. By paying, you can raise this limit to 30,000 words per scan.

The methodology this tool uses to find matches appears highly unreliable. It seems to simply search Google for each sentence in your document, counting it as plagiarism if it finds a match.

It identified only a low proportion of the plagiarism (38%) in our test documents. Due to its methodology, it was usually unable to find full matches, and it performed particularly poorly with scholarly sources such as dissertations and journal articles.

The report shown on the site gives a list of individual sentences marked as plagiarized or original. You can click a link next to each source, but all it does is google the sentence in question. The downloadable report highlights plagiarism within the text and shows a list of sources, but it doesn’t clearly link each sentence with a source.

There is also a language statistics function that lets you see words that appear frequently in the text to help limit repetition.

Search Engine Reports claims not to store any uploaded content in their database. There is no live support, but there is a contact form.

  • Uploaded documents not stored/sold
  • Detects a very low amount of plagiarism
  • Misleading about costs—only free for five documents
  • Low word limit of 800
  • Lots of distracting ads and pop-ups

The tool claims it’s free, but it actually only allows you to upload five documents before requiring you to sign up for one of their many premium plans. These documents have an unusually low word limit of 800.

The premium plans offer options to increase (but not remove) this word limit. The cheapest is $15 per month, which only increases the limit to 1,000 words—a limit many other tools offer for free.

Plagiarismchecker.co gave some of the worst results out of all the checkers we tested, with an average of 30%. It was never able to provide a full match for a source text, only partial.

The tool is frustrating to use due to the high number of ads it displays and the low word limit.

The downloadable report sometimes didn’t include the plagiarism percentage, making it impossible to know how much of the text was plagiarized/original.

The report itself is difficult to read. All plagiarized text is highlighted in one color and is not clearly matched with the source identified for it.

The site claims that uploaded content is not stored in a database or shared with others. It also claims that “our advanced AI-powered algorithm ensures that your content must be protected under the copyright laws.” It’s not clear what this means.

While the site claims to have 24-hour support, there is no live support. There is a contact form on the site.

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

Run a free plagiarism check

If you’re a university representative, you can contact the sales department of Turnitin .

Scribbr is an authorized Turnitin partner

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

  • 99.3 billion current and historical webpages.
  • 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

So, some tools on the list offer citation support while others detect AI content and API integration. But let’s not waste any more time!

Achieve excellence with a thorough plagiarism check and editing! Learn more

Here are the ten best free plagiarism checkers of 2024:

  • Grammarly Plagiarism Checker
  • QuillBot Plagiarism Checker
  • PlagiarismDetector.net
  • Scribbr Plagiarism Checker
  • Small SEO Tools Plagiarism Checker
  • Duplichecker
  • Editpad Plagiarism Checker
  • EasyBib Plagiarism Checker

Let’s see the pros and cons of each one.

#1 Grammarly Plagiarism Checker

Grammarly’s plagiarism checker is renowned for its accuracy and integration with their powerful writing assistant. It checks texts against billions of web pages and ProQuest’s academic databases.

Grammarly’s online plagiarism checker for free gives detailed plagiarism reports with a similarity percentage and links to sources. It also offers comprehensive grammar and spell checks as well as style and tone adjustments.

  • Highly accurate plagiarism detection
  • Protects your data
  • Only 10,000 words in the free version

#2 QuillBot Plagiarism Checker [$8.33/Month]

QuillBot not only provides plagiarism checking but also offers paraphrasing tools to help refine and improve your writing. If you’re using the plagiarism tool for academic purposes, it also highlights missing citations.  The catch is, you have to pay a subscription fee to use it.

The tool accepts a variety of file types including .txt, .pdf, .docx, and .html.  It offers instant plagiarism reports and analysis. If you want to save reports, you can also create an account with them.

  • It supports more than 100 languages. 
  • Workplaces can get a cheaper price if they place more than five orders. 
  • You’ll have to pay $19.95 if you’re not on an annual plan. 

#3 PlagiarismDetector.net

PlagiarismDetector.net offers a straightforward and user-friendly interface that provides quick and reliable plagiarism checks. You can upload a URL or file to check plagiarism online, so you can skip the copy/paste hassle! 

The plagiarism detector produces authentic results in real-time without flagging unreasonable duplication. They employ “deep search” technology to achieve this. They have three paid plans available for instructors or other professionals who need to scan more than 25,000 words per month.

  • It supports multiple languages including Spanish, German, and French. 
  • You can give feedback. 
  • It supports only 1,000 words in the free version. 
  • There are ads and pop-ups on the page. 

#4 Scribbr Plagiarism Checker

Quite popular among students, Scribbr has partnered with Turnitin to offer a highly accurate plagiarism checker. The tool scans your writing against a large database of scholarly articles to produce a detailed similarity report. Their database includes 99 billion web pages and 8 million publications!

The detector offers live chat with plagiarism experts and an option for professional feedback. It supports over 20 languages including Dutch, Portuguese, and Italian.

  • The tool tells the domain, database, and the number of matching words for each source. 
  • It scans your text for spelling and grammar errors . 
  • It’s much more expensive; and charges a per-use rate of at least $19.95. 

#5 Small SEO Tools Plagiarism Checker

This free plagiarism checker tool is part of a larger suite of free SEO tools. It’s particularly popular among bloggers and freelance writers. It offers sentence-level results with the sources flagged.

The plagiarism checker supports documents in multiple languages. You can check for plagiarism free of cost, but there’s a limit of 1,000 words per use, which isn’t ideal. It’s also prone to a little lag and takes time to produce the plagiarism report.

  • Completely free
  • Has a WordPress plugin
  • Intrusive ads on the page
  • May report false positives

#6 Duplichecker [$5/ Week]

Duplichecker has both, a plagiarism checker online for free and a paid version. It’s ideal for quick checks. It includes a grammar checker , which is an added benefit. The tool supports multiple file formats such as .tex, .txt, .doc, .docx, .odt, .pdf, and .rtf. 

Interestingly, this tool offers a “Make it Unique” option that helps you rephrase your writing to avoid plagiarism detection. While this feature won’t be useful for students, it’s a lifesaver for content writers and marketers!

  • Differentiates duplicate and unique phrases
  • Supports seven languages 
  • Has a daily usage limit of 1,000 words
  • Occasionally misses some sources

#7 Editpad Plagiarism Checker

Editpad’s plagiarism checker for students can be used for free. This tool’s robust detection algorithms use deep search and ProQuest technology to detect plagiarism quickly. The tool, along with others on the platform such as Sentence Expander and Thesis Statement Generator, can be quite handy for students.

Editpad Plagiarism Checker supports both text and URL input. While the tool is easy to use, it’s probably not ideal for any heavy lifting. If students, teachers, or bloggers need a quick plagiarism detector for free, this one works best.

  • Supports various file formats such as DOC, DOCX, TXT, and PDF
  • User-friendly and to-the-point
  • Has a limit of 1,000 words
  • Ads can be distracting

#8 EasyBib Plagiarism Checker  

EasyBib offers a comprehensive tool that not only checks for plagiarism but also helps with proper citation, making it ideal for students and educators. This plagiarism detector isn’t free, but it comes with unlimited grammar, citation, and formatting checks.

You can paste text or import papers from your computer and Google Drive to check for plagiarism online. The plagiarism tool is great at catching accidental plagiarism. If you’re looking for an advanced plagiarism checker that also checks grammar, spelling, and citations, this one is it!

  • Unlimited access to the Chegg citation generator
  • Offers detailed feedback on plagiarism
  • Has a library of educational resources
  • Requires a paid subscription
  • Can be slow with large documents

Copyleaks uses advanced AI and machine learning technologies to detect plagiarism in over 100 languages. It detects multiple forms of paraphrasing, performs image-based text plagiarism, and exposes attempts to deceive detection software. It’s used by universities and SEO firms alike, which speaks for its versatility. 

The Copyleaks plagiarism detector tool also offers cloud computing support and API access for developers. It generates comprehensive PDF reports and offers “recurring scans” that protect your work from plagiarism.

  • 20 pages per month for free
  • AI content detection
  • Scalability for businesses and institutions
  • Complex interface for new users
  • Can be slow, taking 2–4 minutes to check 500 words

#10 Quetext [$8.80/Month]

While Quetext’s free online plagiarism checker tool isn’t very convenient, the upgrade is perfect for a student writing their dissertation. It lets you check 100,000 words per month and offers citation support. The tool does a contextual analysis of your writing while flagging plagiarism.

The plagiarism tool combines deep search technology with a wide database consisting of 35 billion websites, 20 million books, and 1 million journals. It is easy to use for students and supports multiple languages including French, Spanish, Italian, Portuguese, German, Arabic, and Russian.

  • Website citation generator and citation assistant

Frequently asked questions

No, the Self-Plagiarism Checker does not store your document in any public database.

In addition, you can delete all your personal information and documents from the Scribbr server as soon as you’ve received your plagiarism report.

Scribbr’s Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker . This means you won’t be charged on a recurring basis – you only pay for what you use. We believe this provides you with the flexibility to use our service as frequently or infrequently as you need, without being tied to a contract or recurring fee structure.

You can find an overview of the prices per document here:

Small document (up to 7,500 words) $19.95
Normal document (7,500-50,000 words) $29.95
Large document (50,000+ words) $39.95

Please note that we can’t give refunds if you bought the plagiarism check thinking it was a subscription service as communication around this policy is clear throughout the order process.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

  • 99.3 billion current and historical webpages.
  • 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

To cater to this, we have the Self-Plagiarism Checker at Scribbr. Just upload any document you used and start the check. You can repeat this as often as you like with all your sources. With your Plagiarism Check order, you get a free pass to use the Self-Plagiarism Checker. Simply upload them to your similarity report and let us do the rest!

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

  • Scans your paper against billions of sources.
  • Identifies text that may be flagged for plagiarism.
  • Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

free download plagiarism checker for thesis

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

  • A chart or graph from another source
  • A paraphrase of an original source
  • Several sources’ ideas summarized into your own paragraph
  • A direct quote
  • All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level.

Frequently asked questions

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.

Small document (up to 7,499 words) £13.95
Normal document (7,500-49,999 words) £22.95
Large document (50,000+ words) £31.95

Similarities in your document are highlighted for quick and easy review. Each colour corresponds to a source in your Sources Overview at the right side of your report.

Information can often be found in more than one place. For this reason, other sources citing the same information you used can come up in your Sources Overview.

The important thing is to make sure you’ve cited the source of the material. Try to find the original source, but if you can’t find it, it’s best to cite the source where you found the information.

Scribbr’s free plagiarism checker estimates the risk of plagiarism by calculating the percentage of text in your document that’s similar to other sources.

A moderate or high risk of plagiarism means that the plagiarism software detected several similarities worth reviewing.

Note that similarities are not necessarily plagiarism. You will need to decide on your own whether your text needs revision or citation.

The free report tells you if your text contains potential plagiarism and other writing issues. The premium report gives you the resources you need to review issues in detail and resolve them.

If you’ve correctly cited all the sources you used, then you do not need to use a plagiarism checker before submitting your paper to your instructor. However, it is very easy to commit plagiarism accidentally, even if you’ve been very careful. To ensure that you didn’t forget to cite anything, you should use a plagiarism checker yourself.

A  plagiarism checker works by using advanced database software to scan for matches between your text and existing texts.

To help you decide which checker to use, we conducted in-depth research comparing popular plagiarism checkers to find out which one is best.

Best plagiarism checker comparison

Your work should not contain any  plagiarism . Even if your score is 1%, you will need to review each similarity and decide whether it’s necessary to revise your work.

But  contrary to popular belief, plagiarism checkers work by detecting not plagiarism, but similarities . Not all similarities found by the Scribbr Plagiarism Checker constitute plagiarism. Our check sometimes flags the following:

  • Properly cited quotes
  • In-text citations or your reference list
  • Commonly used phrases

What should I do with a found similarity?

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

Scribbr’s  Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

  • 99.3 billion current and historical webpages
  • 8 million publications from more than 1,700 publishers such as Springer, IEEE , Elsevier, Wiley-Blackwell, and Taylor & Francis

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.

How you can avoid plagiarizing

ILLUSTRATION

Know the different types of plagiarism

There are several types of plagiarism, and it’s essential to understand the differences to avoid making these mistakes and prevent plagiarism in the classroom.

  • Direct plagiarism: Using someone else’s exact words and using them as your own with no credit to the source. Eliminating portions of the text still qualifies as direct plagiarism.
  • Patchwork plagiarism: Creating new text by combining exact phrases or sentences from multiple sources without acknowledging the original authors or sources.
  • Self-plagiarism: Attempting to reuse or recycle your previous work and claiming it as a new piece of work without mentioning the source of original publication.
  • Source-based plagiarism: Producing false sources within your writing or omitting one or more references from citations.

Cite your sources

Students often think of citations as a simple means of acknowledging another author's work. While this is their main purpose, there are other benefits as well.

Source citations also show readers where to go to learn more. By providing context around the citation in student papers, such as the source medium and when it was published, readers can locate the information more easily. Giving too little source information or improperly formatting it can result in unintentional plagiarism. These mistakes also make it difficult for readers to locate the original source and verify information.

Quetext's citation generator makes it easy for students to accurately cite their sources without slowing down their writing process. Once a user inputs the text, the software identifies the passages that require a citation and subsequently generates it in the style required — APA, MLA, or Chicago.

Always use a plagiarism checker

The best way to avoid severe plagiarism consequences is to use a plagiarism checker. Often, plagiarism is unintentional and results from poor paraphrasing of material found online. Using a plagiarism checker, the student can avoid accusations of any kind of plagiarism and benefit from a close review of the original material.

Quetext's plagiarism checker provides a speedy, easy process for students to receive accurate results, identifying areas of concern and providing on-page solutions.

Plagiarism Checker for Students FAQ

What are the consequences if a student is caught plagiarizing.

The consequences of plagiarism vary according to the student’s academic institution and grade level. For example, a middle school student who plagiarizes within an essay may receive a stern warning and additional instruction related to the process of citing sources or summarizing one’s thoughts.

However, students in higher education institutions guilty of plagiarism in academic papers face much steeper repercussions, including, but not limited, to failing grades and disciplinary or legal action. Factors such as the assignment itself, the instructor, and whether or not it is your first offense impact the outcome.

Depending on the severity of the situation, plagiarism can also impact a student’s reputation or future career opportunities.

How does a plagiarism checker help students?

A plagiarism checker helps students be proactive in finding instances of plagiarism before an assignment is completed and turned in with no way to correct the errors.

In addition, by identifying the potential conflicts early, students can conduct further research to find alternative sources to understand the material better and revise or rewrite the offending passages.

Plagiarism checkers also help students learn innovative writing techniques, improve their writing skills through better research and experience in summarizing ideas, and preserve academic integrity.

Do teachers use plagiarism checkers?

Many teachers use plagiarism checkers to ensure a student’s submission is 100% original work. With the rise of easy-to-use tools like Quetext, checking for authenticity and text matches is a quick and affordable process to scan millions of online data sources.

Using plagiarism checkers also allows teachers to educate their students on the importance of citing sources and the ethical responsibilities of research and opinion writing.

Plagiarism has always been a source of concern for teachers, but until now, options for manual detection have limited their opportunities to identify the problem efficiently. However, the evolution of technology in this area has made the tools more accessible than ever.

How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period or who teach in the areas of English or Literature. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text on web pages.

However, this manner of plagiarism detection is manually intensive and dependent upon unreliable algorithms. Some may use their writer’s intuition by identifying anomalies in sentence structure, inconsistencies in vocabulary or grammar, or a combination of all of these.

Others use more sophisticated and robust plagiarism detection software, like Quetext. Quetext can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing and avoid repeating the same mistakes in the future.

Can students get in trouble for accidental plagiarism?

Yes, students can be penalized for plagiarism, even if it was an accident. Unfortunately, instructors have no way of knowing the intent behind plagiarism. Depending on the type of plagiarism, instructors may allow leeway for students to learn from their mistakes and correct the work without the threat of severe consequences.

However, repeat offenders are less likely to receive this flexibility and may face steeper penalties. Additionally, instructors of college-level courses with clear plagiarism guidelines and policies may be less inclined to let students off the hook and instead enforce severe consequences.

Is there a free plagiarism checker for students?

Yes! Quetext offers both a free and a paid subscription for students to seamlessly verify their writing. Quetext goes beyond traditional plagiarism checkers to provide students with advanced technology that puts content through three layers of evaluation in just a matter of seconds. This level of insight enables students to understand the degree to which the text has been plagiarized and decide whether to rewrite the text or use the citation assistant to cite sources.

Quetext also offers a detailed report students can use to document their editing efforts and present as proof of a plagiarism-free, 100% original content document.

Quetext's plagiarism tool also offers flexible pricing for its Pro features which facilitates the citation of online sources, attributions, and real-time feedback for writing improvement.

How can a student check for plagiarism?

Anyone can enter the text from a research paper into a search engine and find potential matches that identify instances of plagiarized content or duplicate content. However, this method is largely ineffective and does not identify every area of concern.

Students can use Quetext's free online plagiarism checker by creating an account, copying and pasting the text in question into the plagiarism checker, and receiving a comprehensive analysis with color-coded feedback, a plagiarism percentage score, and options for editing the text.

Quetext is one of the best plagiarism checkers available with high-quality insights and accurate results.

Steps to Avoid Plagiarism in Research Work

  • The best way to stay original is: staying original. Don't get me wrong. All I want to say is, think with your own imagination. Paraphrasing is actually detectable if it is not done properly. Also, if you are doing it, you should not forget to add an in-text citation properly.
  • Another important thing is to keep track of your work from the very beginning of your work. You can use cloud services like Evernote and Pocket to keep track of URLs, PDFs, Blogs, Websites, and Other Works.
  • Unorganized papers often lead to plagiarism. You should be very careful while copying word-by-word. You can use "Quotes" to highlight the part which is copied with a source.
  • Never trust Free services. Writing about the thousandth time, Do not use free tools. They will only lead you to false results and the risk of getting plagiarized with your own work. Paying someone to check your work on Turnitin will only lend you to hazard.
  • If Your paper is an assignment, always do everything as instructed by the professor.

Without any doubt, Turnitin is a good tool to detect a similarity between the strings, whether it is a research work or an assignment. It has a huge database of research work and it is capable to find similarity in your content with the previous works.

That depends on the setting teachers are using. Only the examiner and you (human) can judge whether you have plagiarized or not.

Plagiarism Checker X

Some of them are bulk uploading, side-by-side comparison, automatic citation and multiple language support.

Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.

Self-Plagiarism

The concept of thinking that, self-plagiarism is only copying some other's paintings or borrowing someone else's unique idea. In my thoughts like "copying" and "borrowing" can cover the seriousness of the offense.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else's work or ideas and passing them off as one's own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else's artwork and lying approximately it in a while.

Necessity of AI Plagiarism Checker Over Time

DupliChecker's AI plagiarism checker utilizes artificial intelligence to enhance the precision of detecting plagiarism by analyzing various text elements, such as syntax, writing pattern, tone, and rhythm of words. This inclusion of AI simplifies to check AI plagiarism across different domains.

How Does AI Plagiarism Checker Differs from Traditional Methods?

The working of an AI plagiarism checker differs from traditional methods as it organizes your data and analyzes it with advanced machine learning and Natural Language Processing techniques. Later, this AI plagiarism detector compares the comprehended information with millions of web pages’ data available in its databases to find similarities. Lastly, it displays AI plagiarism detected in your content while letting you know its exact percentage. This entire method differs from traditional plagiarism detection methods that use string-matching techniques and provide an approximate estimation of plagiarism that needs to be more accurate.

Plagiarism detector VS Manual checking [Pros and Cons]

It’s boring, time taking and the big thing is the MANUAL! Ah

Who wouldn’t want to skip doing something that technology can do for you with more accuracy and quickly? Right!!!

We know We would! As it can help in many ways, one of which is finding a copy of original content over the internet and informing about it while you are sipping your coffee in dim light, “Sounds Cool”. Or you can go ahead and crosscheck to look for the plagiarized work manually which not only is going to take a lot of time. You need an excellent memory because while reading so many documents you might keep on forgetting the duplication and sources.

Isn’t it enough reason why a plagiarism scanner is used?

Because it is accurate and able to find the copied content real fast to improve academic honesty and whatsoever that does not allow plagiarism. This usually happens in almost every student, professional writer, professor, or content creator’s life that uses the internet to study, teach or deliver their work.

So, they have to be very careful in uploading a part of their work online; the best way is the use of image formation. If someone copies from the image we have developed a tool to find similar image . It will recognize objects on the image and let you know where this object or image is located. In which no one can copy any sort of work, but they will have to write down which people mostly don’t like to do.

Plagiarism in the digital world.

How to Check for Plagiarism: Ensuring Your Work is Original

Plagiarism is a serious issue, both in academic and professional settings. It involves using someone else’s ideas or words without properly citing them. Fortunately, there are several tools and techniques available to help you check your work for plagiarism before you submit it.

Here’s a guide to navigating plagiarism checkers and ensuring your writing is original:

Understanding Plagiarism Checkers:

  • What they do: Plagiarism checkers are software programs that scan your text against a massive database of web pages, articles, and academic journals. They identify any significant matches, highlighting potential plagiarism.
  • Peace of mind: Knowing your work is original reduces stress and avoids accusations of plagiarism.
  • Catching unintentional mistakes: Even paraphrasing without proper citation can be flagged, prompting you to double-check your references.
  • Not perfect: Plagiarism checkers are powerful, but they can’t catch everything. For instance, they may miss paraphrased content that retains the original meaning.
  • Limited databases: Free checkers might have smaller databases, potentially missing less common sources.

Using a Plagiarism Checker:

There are several free and paid plagiarism checkers available online. Here’s a general process for using them:

  • Choose a checker: Consider factors like features, database size, and cost. Free options are great for basic checks, while paid services might offer more in-depth analysis.
  • Upload your text: Most checkers allow you to copy and paste your text or upload a document file.
  • Run the scan: Initiate the plagiarism check and wait for the results.
  • Analyze the report: The report will highlight any matches. Review each flagged section carefully.

Beyond the Checker: Avoiding Plagiarism

  • Proper citation: Always cite your sources correctly, following the appropriate style guide (e.g., MLA, APA).
  • Paraphrase effectively: Don’t simply copy and change a few words. Rephrase the information in your own words, but still cite the source.
  • Focus on understanding: The goal of research is to learn and develop your own ideas. Don’t rely solely on copying others’ work.

Plagiarism is a serious offense that can hurt your academic or professional career. To avoid accusations of plagiarism, it’s important to use a plagiarism checker to ensure that your work is original.

Ensuring the originality of your content is essential, and the best plagiarism checkers mentioned above can assist you in avoiding the severe consequences associated with plagiarism.

By considering factors such as content database size, user interface, additional features, and pricing plans, you can select the most suitable plagiarism checker to meet your specific needs. Invest in these reliable tools to enhance your writing integrity and achieve peace of mind.
