Free tools for AI search

Before ChatGPT, Claude or Perplexity can recommend you, they have to be able to read your site. These free tools check that in seconds. No signup, and no AI involved: they fetch and read your public pages.

• AI crawler checker

  Enter a page and see which of 14 AI crawlers your robots.txt lets in, the exact rule that decides it, and the lines to paste if one you want is blocked.

  • 14 AI bots: allowed, blocked or partly blocked
  • The robots.txt rule behind each verdict
  • noindex in meta tags and X-Robots-Tag
  • A copy-paste robots.txt fix
