AI Content Detector
AI Content Detector estimates how likely a piece of text was written by AI. The quick check runs entirely in your browser using writing-pattern analysis — sentence-length variance (“burstiness”), repetition, and common AI filler phrases. An optional deep analysis, which you trigger by clicking a button, sends your text to our server (and on to AI models) for a more accurate, blended score; it is analysed for that and not stored.

Preguntas frecuentes
Is this 100% accurate?
No. No AI detector is reliable — even paid ones produce false positives. This is an indicator based on writing patterns and model estimates, not proof. Never use it alone to accuse someone of cheating.
How does it work?
The quick check scores statistical writing signals in your browser (sentence-length variance, repetition, vocabulary diversity, known AI filler phrases). The optional deep analysis blends those with one or more AI detection models run on our server.
Is my text uploaded?
Only if you choose to. The quick check is 100% in your browser. The text is sent to our server (and the AI models it uses) only when you click “Run deep AI analysis” — it's analysed for the score and not stored. Avoid pasting anything sensitive if you use deep analysis.
