Offline AI Detector door Arthur

Highlights text that looks like it was written by ChatGPT, Claude or similar tools

How it works:
- Scans the page for text
- Checks each one against patterns common in AI writing: overused words, uniform sentence length, hedge phrases, formal structure
- Highlights suspicious blocks with a color based on probability
- Hover the cursor to see the score and which patterns triggered

Four detection methods:
1. Vocabulary - words AI loves ("comprehensive", "delve", "facilitate")
2. Phrases - common AI constructions ("it's worth noting", "in order to")
3. Statistical - sentence rhythm, paragraph uniformity, punctuation patterns
4. Structure - numbered lists, transition words, formulaic conclusions

Everything runs in your browser. No servers, no API calls, no data collection. Works offline

Settings let you adjust sensitivity or switch between Precise/Balanced/Aggressive modes
