AI Content Detector
Paste text to estimate whether it was written by AI. The checker analyses transparent writing signals — sentence variation, AI cliché phrases and lexical diversity — entirely in your browser. It is an estimate, not proof: false positives are common, so never use it alone to accuse anyone.
Frequently asked questions
How does this AI detector work?
It analyses transparent writing signals — sentence-length variation (burstiness), common AI cliché phrases, transition-word density and lexical diversity — and combines them into a likelihood score, entirely in your browser. Each signal is shown so the result is explainable rather than a black box.
Is the AI detector accurate?
Treat it as an estimate, not proof. No detector is reliable enough to accuse anyone, and false positives are common on short, formal, technical or non-native English text. Use it as a hint to review writing, never as the sole basis for a grade or accusation.
Is my text uploaded anywhere?
No. The analysis runs entirely in your browser and your text never leaves your device.
Can it detect ChatGPT, Gemini or Claude text?
It looks for patterns common to AI writing in general rather than a specific model. Heavily edited AI text and very polished human text can both fool any detector, so use the result as a hint only.
