AI score, official Claude watermark (once live), and invisible character detection — three clear signals, never blended together.
AI Watermark Detector analyzes any text for signs of AI generation — with three clearly separated signals, never blended into one misleading score.
INVISIBLE CHARACTERS & HOMOGLYPHS
100% verifiable offline: the app looks for invisible Unicode characters and letters from other alphabets substituted for Latin ones — real techniques used to hide manipulated text.
AI SCORE (powered by Mistral)
A writing-style estimate: probability the text is Claude's, probability it's AI in general, and if not, the most likely model. Clearly labeled as a statistical hint, never proof.
OFFICIAL CLAUDE WATERMARK
Anthropic confirmed it embeds a real cryptographic watermark in Claude-generated text. As soon as their public detection API ships, the app connects to it automatically — no update needed.

TRANSPARENCY FIRST
This app never claims to prove a text is human or AI-written with absolute certainty. Every signal is labeled with its real reliability level.
