Unicheck Plagiarism Detection

Unicheck will be unavailable in Canvas after December 28, 2018, and we recommend that instructors who choose to use these tools select Turnitin as the Plagiarism Framework option for new and existing assignments moving forward.

Unicheck is a web-based plagiarism and content checker that detects same or similar content in documents and webpages. Unicheck uses an algorithm to check for plagiarized content by searching for text that is identical to the document being checked. 

As a third-party service, Unicheck integrates with Canvas Assignments to allow instructors to detect plagiarism in assignments submitted in Canvas. Students can also check their own papers to make sure all their sources are properly acknowledged.

Note: The instructions below explain how to use the new version of the tool. If you have existing assignments or prefer to use the external version of the tool, the instructions are at the bottom of this page.

Unicheck Originality Scores

After a submission has been processed, a report is generated detailing the percentage of text in the submitted paper that matches existing sources. The report also shows the suspected sources of each section of the submitted paper that returns a match. You can omit matching sources from the report and process it again.
