About
AI Plagiarism Checker runs submitted text through semantic analysis to find not just exact matches but also paraphrased passages that retain the original meaning. It accepts plain text, PDF, and Word files, processes up to 200,000 words per scan, and returns a similarity score alongside identified source references. Content is encrypted during processing and deleted automatically afterward. The service supports multiple languages and is free with no hidden charges, making it practical for students submitting academic work, researchers verifying originality, and editors checking content before publication.
