Can AI engines actually read your site?
Enter your domain. We check your robots.txt and your firewall against the crawlers behind ChatGPT, Claude, Perplexity, Gemini, Copilot and Apple Intelligence.
Questions
- Why would AI crawlers be blocked?
- Many sites block them by accident — a robots.txt rule copied from a template, or a firewall/bot-protection setting that challenges anything that isn't a normal browser.
- What happens if they're blocked?
- If an engine can't read your pages, it can't quote them. When buyers ask ChatGPT or Perplexity for recommendations, the engine leans on other sources instead.
- Is this test accurate?
- It reads your live robots.txt and requests your homepage using each crawler's published user agent. Some firewalls verify crawlers by IP address, so treat a firewall pass as a good sign rather than a guarantee.
