What the Robots.txt & AI Crawler Checker checks

Audit a site's robots.txt, test whether a crawler may fetch a path, and see which search and AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more) are allowed.

  • Every rule that blocks a search or AI crawler
  • The rule that matches a given path for a given crawler
  • Access for GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more
  • The exact line to change

What it does not do

  • Rendering or fetching the tested path itself
  • Sitemap validation or indexation claims
  • Proof that a crawler obeys robots.txt

Questions about the Robots.txt & AI Crawler Checker

How do I block or allow GPTBot in robots.txt?
Add a group for its user agent: "User-agent: GPTBot" followed by "Disallow: /" to block it or "Allow: /" to allow it. A crawler follows only the most specific group that names it, so a GPTBot group overrides the "User-agent: *" rules. Run the checker after you publish to confirm which rule now matches.
What does Google-Extended control?
Google-Extended is a robots.txt token that controls whether Google may use your content for its Gemini models and grounding. It does not change how Googlebot crawls or ranks your pages in Google Search.
Do AI crawlers obey robots.txt?
The major operators say their crawlers follow it, but robots.txt is a request, not an access control, and this checker cannot prove what a crawler does. To see what bots actually fetch, paste your access log into the AI Bot Log Analyzer.
How much does the Robots.txt & AI Crawler Checker cost?
10 credits per run, shown before the run starts. An AI agent can run the same tool over the REST API or MCP with a workspace API key.
