Frequently asked questions
The Scribbr 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.
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.
The Scribbr Plagiarism Checker, powered by Turnitin, compares your submissions against the largest and fastest-growing content database in the world:
- Over 91 billion current and historical web pages.
- Over 69 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.
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 checks your document for plagiarism only once. You can use the “exclude text” feature to exclude similarities that you’ve resolved, which automatically updates your similarity score.
If you would like to recheck your entire document, you can purchase a new plagiarism check at the regular price. We don’t currently offer a subscription service.
No, the Scribbr Plagiarism Checker does not publish your submissions in any public database (unlike other plagiarism checkers).
No, your teacher, professor, or admissions officer will not be able to see your submissions at Scribbr because they’re not added to any shared or public databases.
