Enter your domain. We read your robots.txt and show you, crawler by crawler, which AI bots you allow and which you block — so you never go invisible by accident.
Free · no signup · reads your live robots.txt
robots.txt is the first thing an AI crawler checks before reading you. Many templates and CDNs block GPTBot, ClaudeBot or PerplexityBot by default — so when an assistant searches live, your content is off-limits and it answers without you. This checker shows whether your policy is really what you think it is. Read the full guide →
It fetches your /robots.txt and reports, for each documented AI crawler (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot and more), whether your rules allow or block it. Free and no signup.
Not entirely: blocking GPTBot stops training/indexing, but live browsing (ChatGPT-User) uses a different user-agent. Still, blocking the crawler reduces what the assistant knows about you. Decide it on purpose.
Then AI bots enter by default — you block none, but you also declare no policy or sitemap. The checker will suggest an explicit robots.txt you can publish.
No. AI crawlers are separate from Googlebot. Blocking them does not change your Google ranking — only your visibility to AI assistants.
