What can read your robots.txt?

Paste it and see which AI crawlers — GPTBot, ClaudeBot, PerplexityBot and every other one — may read your site.

Why this matters

Search engines like GPTBot, ClaudeBot and PerplexityBot do not use Googlebot. They are separate user-agent tokens, and each one is allowed or blocked on its own.

  • Blocking GPTBot stops training crawls but says nothing about ChatGPT search — that one is OAI-SearchBot.
  • Google-Extended does not affect Google Search at all; it only governs Gemini and Vertex training.
  • ChatGPT-User fetches pages a person asked for, so it usually ignores robots.txt anyway.
