An independent tool to check whether text may be AI-generated, providing an AI probability score and sentence-level analysis without requiring an account.

AI Detector is a free, independent AI content checker designed for users who want a quick way to analyze text for patterns that may indicate AI-generated or heavily AI-assisted writing. Users paste their content and receive a clear AI probability score along with sentence-level feedback identifying specific passages that may require closer inspection. The tool is built for fast, low-friction checks without account creation or payment, and can be used by students, teachers, writers, editors, businesses, and publishers. Results are treated as probabilistic signals to support human judgment rather than definitive proof of authorship.
Pricing model: Free
Free to use with unlimited checks and no signup required.

They can estimate whether text contains patterns associated with AI-generated writing, but cannot confirm authorship with complete certainty.
Formulaic structure, repetitive language, short samples, grammar correction, and non-native writing patterns can all influence a detector.
Scores should be treated as an initial signal and reviewed alongside drafts, sources, prior writing, classroom performance, and direct discussion.
It may still identify edited AI content, but results depend on how substantially the text was changed and how much original reasoning was added.
