The Scribbr Plagiarism Checker detect similarities between your paper and a comprehensive database of web and publication content. Because many students write their references in the same way (for instance in APA Style), a plagiarism checker finds many similarities with these sources.

However, it's important to note that Scribbr's plagiarism checker is powered by the same technology as Turnitin, therefore if you have access to Turnitin through your school or university, Scribbr essentially offers scans of the same quality along with some additional paid options.

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.

However, since the rise of AI content generation, Scribbr moved past just detecting plagiarism by offering an AI detection tool as well.
