Frequently asked questions: Freemium Plagiarism Checker Landing Page

How accurate is Scribbr’s plagiarism checker?: 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.
What plagiarism and AI detection software does Scribbr use?: 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.
To which databases will my document be 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.
How long does it take to generate the plagiarism report?: Generating your (free or premium) plagiarism report takes between 1 and 10 minutes, depending on the document size.

In that time, your document is compared to the world’s largest content database, with over 99 billion webpages and 8 million publications.
What is the difference between the free and premium report?: 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.

Will Scribbr give the same result as my university’s plagiarism checker?: 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!
