AI crawlers.Can they read your site?
Paste your robots.txt. We test it against every crawler the AI makers document, without fetching your site.
The short answer
Updated
The AI crawler checker reads a robots.txt file you paste in and shows whether each documented AI search crawler, such as OAI-SearchBot, PerplexityBot, Googlebot and bingbot, may fetch a page on your site. It uses the user agents each maker publishes, explains what blocking each one does, and runs entirely in your browser without visiting your site.
1 of 16 crawlers are blocked from this page.

robots.txt is a request, not a lock. Some user-triggered fetchers say they may ignore it, and a firewall can still block crawlers this file allows.
How it works.No hidden steps.
- 01Open yoursite.com/robots.txt, copy everything and paste it in.
- 02For each crawler, the checker uses the group that names it, or the * group if none does.
- 03Within that group, the longest matching rule wins, and Allow wins a tie, as the robots.txt standard says.
- 04Change the test path to check a specific page, such as a service page.
What we store: nothing. The checker never contacts your site, and your robots.txt stays in your browser.
Questions people ask.Short answers.
Where do I find my robots.txt?
At the root of your domain, for example yoursite.com/robots.txt. If there's nothing there, crawlers treat the whole site as allowed.
Should I block GPTBot?
It's your choice. GPTBot collects training data; ChatGPT search uses OAI-SearchBot. Blocking GPTBot doesn't remove you from ChatGPT search.
Why isn't Grok in the list?
Grok's maker doesn't document a crawler or robots.txt token, so there's nothing official to test.
