AI Crawler Checker
Enter any domain and find out which AI crawlers can actually access your site. We fetch your robots.txt and check every major AI bot.
Why This Matters
If your robots.txt blocks AI crawlers, they cannot read your content. No reading means no citing. Many default CMS configurations accidentally block AI bots.

Crawler Questions
If GPTBot is blocked, ChatGPT cannot crawl your site for fresh content. It may still reference older cached data, but new content will not be indexed. Blocking GPTBot means you are invisible to the world's most popular AI assistant.
No robots.txt means all crawlers (including AI bots) can access your entire site. This is actually fine for most sites. But adding an explicit robots.txt with Allow rules makes your intent clear and is considered best practice.
Yes. robots.txt supports per-bot rules. You can allow GPTBot and ClaudeBot while blocking Bytespider, for example. Use our robots.txt generator to create a custom config.
