Bot or not?

BotOrNot uses Claude AI to analyze linguistic patterns that distinguish human writing from AI output. It looks for over-hedged language, generic transitional phrases, lack of typos or slang, suspiciously perfect structure, and the absence of personal stakes or emotional authenticity — all common tells in AI-generated text.

It's highly accurate for clearly AI-generated content and clearly human content. The "uncertain" zone — short posts, highly edited human writing, or AI that's been humanized — is genuinely difficult. We show you a confidence score so you always know how certain the result is. No tool is 100% accurate.
