AI Crawler robots.txt Checker

Paste your robots.txt to see which AI crawlers can read your site: GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and more. Find out whether you are blocking AI search by accident, then generate a policy that keeps you visible in AI answers.

1. Paste your robots.txt

Open yourdomain.com/robots.txt in a new tab, copy everything and paste it here. Nothing is uploaded or stored: the check runs in your browser.

2. Crawler by crawler

Rules are matched the way major crawlers read robots.txt (RFC 9309): the most specific user-agent group wins, otherwise the * group applies; within a group the longest matching rule wins and Allow wins a tie. * and $ wildcards are supported.

3. Build a recommended AI crawler policy

Pick a stance. The snippet updates as you choose. Add it to your robots.txt as its own block, separated from other groups by a blank line.


Blocking Google-Extended or Applebot-Extended does not affect Google or Apple search rankings. User-triggered fetchers may ignore robots.txt because a person asked for the page.
