Freemium
Plagiarism and AI-content checking for educators, students, writers, and institutions.
What is PlagiarismCheck.org?
PlagiarismCheck.org is a web-based originality checker for educational institutions and individual writers. It compares submitted writing with publicly available resources and can report text similarity, identify likely AI-generated content, and show source links for review. The service also offers authorship verification for comparing a student's work with their previous writing. Its purpose is to help users review originality and investigate questionable passages, rather than replace human assessment.
What can PlagiarismCheck.org do?
AI-content detection
The service analyzes text for signs of AI-generated content and marks passages it considers likely AI-written.
Detection of disguised similarities
Its analysis is designed to flag substitutions, rearranged wording, synonymization, and other changes that can make copied text less obvious.
Fingerprint authorship verification
Fingerprint compares a student's submission with their previous writing style to help identify possible changes in authorship.
Batch document review
Users can upload multiple documents and run checks together, supporting assignment review without searching each passage manually.
Education platform integrations

Educators can check essays and other coursework for matching sources, inspect linked references, and use the report as an input to academic-integrity review.
“Check a draft before submission”
Students can review essays, theses, or other academic writing for overlooked overlap and revise passages that need clearer attribution or original wording.
“Verify authorship consistency”
Schools can compare a student's work with earlier writing through Fingerprint when they need to investigate whether a submission is consistent with that student's style.
“Screen articles and other creative writing”
Writers and content creators can scan drafts for accidental similarities before publication and inspect passages identified in the report.
