Free AI Checker and AI Detector Online

Yes. Lynote offers a free AI detector for checking text online. You can paste text or upload a document and run your first AI check without creating an account. Higher usage limits are available on paid plans.

AI detectors can be useful, but no detector is perfect. Lynote is built for high-confidence AI detection and gives sentence-level highlights so you can review the result instead of relying on one score alone.

AI detectors analyze writing patterns such as word choice, sentence rhythm, predictability and structure. AI-generated text often has smoother, more repeated patterns than human writing. Lynote checks those signals and returns AI-generated, human-written and mixed scores.
