AI Crawler Checker

AI crawlers are bots operated by AI companies — OpenAI's GPTBot, Anthropic's ClaudeBot, Google-Extended, Apple's Applebot-Extended, Perplexity-User, ByteDance's Bytespider, and roughly a dozen others — that fetch web pages for two purposes: building model training datasets and powering real-time AI search. They obey robots.txt by user-agent string, just like Googlebot, but each operator typically runs separate bots for training versus search, so a single Disallow line rarely covers everything you intend. Blocking training bots opts you out of model training; blocking search bots removes you from AI Overviews, ChatGPT citations, and Perplexity answers — usually the opposite of what publishers want. This checker fetches your robots.txt and tells you which of the 16 known AI crawlers can reach your site, then gives one-click snippets to fix any gaps. While you're auditing, run the SEO Checker for full-page issues or check rendering with the Mobile-Friendly Test.
