The statistics below are measured in your browser. "Analyze Text" also sends the text to our AI provider for a second opinion. No detector is reliable enough to prove who wrote a text, so treat the result as an estimate, never as evidence.
About AI Content Detector
Our AI Content Detector (often searched as an ai contect detector) is a free online utility to run an instant ai content check free of charge. Working as an ai content analyzer and ai calculator text tool, it estimates whether text was written by AI such as ChatGPT, Claude or Gemini: it measures writing patterns in your browser (sentence-length variation, vocabulary variety and AI-typical phrases, highlighted sentence by sentence) and asks an AI model for a second opinion when you click Analyze. Free with no sign-up; results are estimates, not proof.
