AI crawler access check
Type in a domain and this checks whether GPTBot, ClaudeBot, PerplexityBot, CCBot, and Google-Extended can actually reach and read it, plus a few other things that quietly block AI visibility. Free, instant, no email required.
What this checks
The check runs against facts that are true or false, not scores. It reads your robots.txt and reports whether each of the five AI crawlers, GPTBot, ClaudeBot, PerplexityBot, CCBot and Google-Extended, is allowed to reach the site. It looks for an llms.txt file, tests whether your homepage is readable without running JavaScript, and confirms the basics: structured data, title, meta description, canonical, sitemap, accidental noindex, and mixed content.
What it will not tell you
Whether AI tools actually cite you. Nothing can check that from the outside, and any tool claiming to is selling a score, not a fact. Access is the precondition: if a crawler cannot reach the page, you are invisible to it, and that part is checkable. If you want the full picture, one buyer question at a time across five engines, that is what the audit does by hand.
