If AI crawlers can't access your content, it can't be cited in AI-generated answers from ChatGPT, Claude, or Perplexity. Allowing them is a business decision, similar to allowing search engine indexing.

Know What AI Sees Before You Wonder Why You're Invisible
As ChatGPT, Claude, Perplexity, and Google's AI Overviews increasingly answer questions directly instead of sending a click to your site, whether your content ever reaches those answers now depends partly on whether your
robots.txt allows their crawlers in
the first place. Many sites unknowingly block every AI crawler by copying an overly broad
"block all bots" rule years ago — this tool reads your live robots.txt and tells you exactly
which AI crawlers can currently access your site, and which ones are shut out.
How It Works
1. Enter a Domain
Any domain — no login or verification needed.
2. We Fetch robots.txt
Read live, directly from your server.
3. See Every Bot's Status
Allowed, Blocked, or Partially Blocked — with the exact rule that determined it.
4. Fix What You Want
Update your robots.txt with our generator if anything needs changing.

FAQsAI Crawler Access Checker
Why would I want to allow AI crawlers on my site?
Does blocking a crawler guarantee it stays out?
No. robots.txt is voluntary. Reputable companies say they respect it, but it has no technical enforcement.
What's the difference between Google-Extended and Googlebot?
Googlebot handles search indexing. Google-Extended separately controls whether your content trains Google's AI and powers AI Overviews — you can block one without blocking the other.
