PlagiarismCheck.org
FreemiumPlagiarism checker and AI detector for schools, students and businesses
What is PlagiarismCheck.org?
PlagiarismCheck.org scans text for copied passages and for signs of AI generation, returning a similarity percentage for each document. It is used by K-12 schools, universities, teachers and individual writers, with a separate business offering.
Educators can run checks inside the tools they already use: there are integrations for Canvas, Moodle, Google Classroom, Schoology, Brightspace, Blackboard and Populi, plus a Google Docs add-on. Platforms that want checking built into their own product can use the plagiarism check API.
Alongside the core checker, individuals get a grammar checker, a citation generator, an essay grader and a topic generator. Organizations and individuals buy on separate pricing tracks.
