What users say Editorial summary

Undetectable AI is commonly used by students, editors, and content managers who want a fast, free way to check whether a piece of text is likely AI-generated. A frequently noted strength is that both the web tool and browser extension are free with an available API. A common limitation is that detection reliability on short or heavily edited text is not independently quantified.
