Unicheck is a plagiarism checker software for educators, students, and content teams to verify originality of written work. Acquired by Turnitin, the tool integrates with LMS platforms like Canvas to scan submissions against open-access web sources and a content database, surfacing similarity reports with highlighted matches and source links. It is being phased out as Turnitin migrates customers to Turnitin Similarity, but remains in active use for academic integrity workflows where teams need straightforward similarity scoring per submission.
