2Built this after finding that 44% of sites blocking GPTBot also block OAI-SearchBot without realizing it's a different crawler with a different job. Wanted a free, no-signup way for anyone to check their own site in seconds, backed by real census data instead of a guess.
Useful tool and the 5,000-site robots.txt census backing it is a nice touch. One thing a lot of people get wrong: blocking Google-Extended does not remove you from AI Overviews in Google search, it only affects training/grounding, while GPTBot and PerplexityBot rules directly decide whether you get cited inside those tools. If your report spelled out that difference per crawler, people would know exactly what they gain or lose before editing their robots.txt. I'd try this on a couple of sites before trusting any crawler-blocking advice.
