Frequently Asked Questions

Is this 100% accurate?
No. Heuristic detection of GPT/Claude-style patterns. False positives common (some humans write very formally), false negatives common (good prompting evades). Use as one signal among many.
Why are em-dashes a flag?
GPT-4 and Claude consistently overuse em-dashes (—). Real humans rarely use them at this density. Statistical pattern across millions of AI samples.
AI-content SEO penalty?
Google does NOT penalize AI content per se. They penalize unhelpful, generic content — which most AI content happens to be. High-quality AI-assisted writing ranks fine.
