AI-bot robots.txt audit
Why a wildcard block isn't enough
Most AI crawlers explicitly document that User-agent: * alone doesn't opt content out of their training set — they require their vendor-specific UA to be named. GPTBot ignores the wildcard for training purposes. Google-Extended is a separate knob from Googlebot. Applebot-Extended is separate from Applebot. This tool audits each known AI UA individually and generates the exact directives you need.
