AI detection is probabilistic, not absolute. Our tool provides a 'likelihood' score based on common patterns in LLM outputs. It is best used as a signal, not definitive proof.

It works best on English, but also supports major languages like Spanish, French, and German.

Yes. AI-humanized text or heavily edited AI content may score lower. No detector is perfect as generative models and detection methods both continuously improve.

If AI-generated text has been significantly rewritten by a human or processed through an AI humanizer, the AI patterns are reduced and the detector may return a lower AI probability score. The detector looks for persistent statistical patterns: a light edit may not remove all signals, but a thorough human rewrite substantially reduces detection accuracy. This is why AI detection results should be treated as probabilistic indicators rather than definitive proof.
