AI Crawler Checker instantly tells you whether your robots.txt allows or blocks the crawlers that decide if ChatGPT, Claude, Perplexity, and Google AI Overviews can cite your content. Most sites get this wrong: every major AI vendor runs two different crawlers, and they do different jobs. A...

As answered by people managing AI Crawler Checker and React-Ionic.
AI Crawler Checker's answer
Other checkers list bots and say "allowed" or "blocked". We separate the crawlers that decide AI citations from the ones that only train models — GPTBot blocked costs you nothing, OAI-SearchBot blocked costs you every ChatGPT citation. 14 named agents, grouped by what each controls, with real robots.txt precedence parsing instead of string matching. Free, no signup.
AI Crawler Checker's answer
Most checkers string-match bot names. We implement robots.txt precedence the way crawlers actually resolve it — most-specific group wins, * is only a fallback, wildcards and longest-match honoured — so configurations that trip up simpler tools get read correctly. And we tell you whether a block matters: GPTBot blocked costs nothing, OAI-SearchBot blocked costs every ChatGPT citation. 14 agents, grouped by what each controls. No signup, no email wall.
AI Crawler Checker's answer
Marketing and SEO leads who've been asked whether their brand appears in ChatGPT, Perplexity or AI Overviews and have no way to check — plus the technical SEOs and developers who actually own robots.txt and have to make the fix. The tool is built for that handoff: plain-language consequences for the first group, exact robots.txt parsing the second group can trust.
AI Crawler Checker's answer
It began as one check inside a larger SEO and AI-visibility audit, and it was the check people reacted to most — so in July 2026 we made it free and standalone. Then we found our own version was wrong: it applied the User-agent: * group even when a crawler had its own, reporting an explicitly-allowed PerplexityBot as blocked. Rewriting that parser to follow real robots.txt precedence is why we trust the verdict now.
AI Crawler Checker's answer
AI Crawler Checker is free and requires no account, so there are no customers in the usual sense — we don't know who uses it, by design. It's used by SEO and marketing teams checking sites they're responsible for; usage skews heavily to desktop and to the US, UK and EU.
