Visit PlagiarismCheck.org

PlagiarismCheck.org is a plagiarism checker and AI detector that scans text for similarity with sources, identifies AI-generated content, and verifies authorship through Fingerprint, which compares a paper against the student's previous writing style. It produces downloadable reports with links to matched sources and similarity percentages, and can analyze multiple documents at once.

The platform integrates with LMS platforms including Canvas, Moodle, Google Classroom, Schoology, Brightspace, Blackboard, and Populi, along with a Google Docs add-on and a plagiarism check API. Additional tools include a Grammar Checker, Citation Generator, Essay Grader, Topic Generator, and a Chrome extension. It serves K-12, higher education, teachers, students, writers, businesses, and content creators.

Organizations can request a quote for Advanced or Pro subscriptions, which are web-based accounts with no installation required. These editions include LMS integration, institutional archives, Fingerprint authorship verification, training and onboarding, and a personal account manager. Features can be customized, and plans can be upgraded or downgraded. Individuals can check text for free, and a free AI checker is available.
