Extensive research shows that Scribbr's plagiarism checker, in partnership with Turnitin, detects plagiarism more accurately than other tools, making it the no. 1 choice for students.
Scribbr is an authorized partner of Turnitin, a leader in plagiarism prevention. Its software detects everything from exact word matches to synonym swapping.
Your submissions are compared to the world’s largest content database, covering 99 billion webpages, 8 million publications, and over 20 languages.

You would never copy-and-paste someone else’s work, you’re great at paraphrasing, and you always keep a tidy list of your sources handy.
But what about accidental plagiarism? It’s more common than you think! Maybe you paraphrased a little too closely, or forgot that last citation or set of quotation marks.
Even if you did it by accident, plagiarism is still a serious offense. You may fail your course, or be placed on academic probation. The risks just aren’t worth it.
Scribbr is committed to protecting academic integrity. Our plagiarism checker software, Citation Generator, proofreading services, and free Knowledge Base content are designed to help educate and guide students in avoiding unintentional plagiarism.
We make every effort to prevent our software from being used for fraudulent or manipulative purposes.
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 also powered by Turnitin software and includes the Turnitin AI Writing Report.
Note that Scribbr’s free AI Detector is not powered by Turnitin, but instead 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 |

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.
