To check an assignment for plagiarism in Canvas, enable the Checkmark Plagiarism LTI 1.3 tool in your Canvas assignment settings—which automatically scans submissions against web databases and peer papers, embedding side-by-side source matches directly inside Canvas SpeedGrader.
Canvas LMS does not include a built-in internet-wide plagiarism scanner by default. Instead, institutions integrate certified external tools via LTI (Learning Tools Interoperability). With Checkmark Plagiarism's Canvas Integration, instructors can enable automated plagiarism checking with a single checkbox when creating an assignment. As soon as students submit their essays, Checkmark scans their text, flags matching sources, and renders interactive source cards directly in SpeedGrader.
Below is a step-by-step tutorial on setting up plagiarism checks in Canvas and interpreting similarity reports.
Checkmark Plagiarism powers seamless Canvas workflows by pairing plagiarism detection with essay writing playback, AI detection, autograding, and native Canvas LMS integration.
