AI Crawlability Checker

See exactly what AI answer engines can — and can't — read on your site.

  • robots.txt rules for 11 AI crawlers
  • noai / noimageai meta and X-Robots-Tag
  • JavaScript-only rendering
  • llms.txt and sitemap.xml

How the AI crawlability checker works

The checker fetches your robots.txt, homepage HTML and HTTP headers exactly the way an AI crawler would, then evaluates each of 11 AI user agents against your rules. It runs in seconds, needs no signup, and reads a single URL rather than crawling your whole site.

  1. 1Enter any public URL — no signup, no crawl of your whole site.
  2. 2We fetch your robots.txt, homepage HTML and HTTP headers the way an AI crawler would.
  3. 3Each of 11 AI user agents is checked individually against your robots.txt rules.
  4. 4You get a per-bot allow/block verdict, the technical signals, and specific fixes.

What each signal means

AI visibility comes down to four technical signals. The checker reports each one with a plain-language verdict and a fix.

Per-bot robots.txt access
Whether each AI crawler (GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended, CCBot and more) is allowed or blocked, and the exact rule responsible. A single Disallow can remove you from an engine entirely.
noai / noimageai meta & X-Robots-Tag
Opt-out directives — in a <meta name="robots"> tag or the X-Robots-Tag HTTP header — that tell AI engines not to use your content even when crawling is allowed.
JavaScript-only rendering
Whether your content exists in the initial HTML. Most AI crawlers do not run JavaScript, so content injected client-side is effectively invisible to them.
llms.txt & sitemap.xml
Discovery files at your site root. A sitemap helps crawlers find every important page; llms.txt is an optional, emerging map of your key content for language models.

What the results mean

Being crawlable is necessary but not sufficient for citation — allowing a bot makes you eligible, while clarity, authority, and structure decide whether you're actually cited. For the full picture, read the complete AI crawlability guide.

Frequently asked questions

Is the AI crawlability checker free?

Yes. The checker is free and requires no signup. Enter a public URL and you get a per-bot access verdict, the technical signals AI engines rely on, and specific fixes — in seconds.

Which AI crawlers does it check?

Eleven AI user agents are tested individually: GPTBot, ChatGPT-User and OAI-SearchBot (OpenAI), PerplexityBot, ClaudeBot and anthropic-ai (Anthropic), Google-Extended and Googlebot, plus CCBot, Bytespider, Applebot-Extended and Meta-ExternalAgent — rather than assuming Googlebot speaks for all of them.

Does a passing check guarantee my site will be cited by AI?

No. A pass means AI engines can reach and read your content — that makes you eligible, not guaranteed. Whether you are actually cited depends on clarity, authority, source-grounding and a direct-answer structure, which the guides cover.

Does the checker crawl my whole site?

No. It fetches your robots.txt, homepage HTML and HTTP headers for the URL you enter — a fast, lightweight read, not a full-site crawl.
