ChatGPT Detector
Human text or AI text?
Paste any paragraph and get a 0-100 likelihood score with a signal-by-signal breakdown: stock phrases, sentence rhythm, word choice and tone. Runs entirely in your browser - nothing is uploaded. No signup.
Signal breakdown
Flagged phrases
Text with flagged phrases highlighted
How it works: six local signals are combined into one score - stock AI phrases (30%), sentence-length uniformity (17%), repetitive openings (15%), missing casual tone (16%), formal word choice (12%) and punctuation variety (10%). Everything runs in your browser with detect-engine.js; the text never leaves this page. Honest limits: detectors are probabilistic - edited AI text can score lower, and formal human writing can score higher. Use the breakdown as a hint, not proof.
