Free AI Crawlability Checker for any page.

We request your page the way ChatGPT, Claude and Perplexity do, with no JavaScript, and show you exactly what they can read.

JavaScript rendering SEO

A browser view does not prove AI crawlability.

A browser runs JavaScript before showing the page. An AI crawler may read only the original HTML response. This difference matters for server-side rendering SEO and technical visibility.

The finished page

The browser runs JavaScript and shows the content available after the page finishes loading.

Raw HTML

The first response

The crawler reads the HTML returned before JavaScript runs. Client-only content may be missing.

0 readable words

Evidence in the report

What this crawlability checker measures

The report separates rendering, content, and access signals so you can see what an AI crawler received.

Readable raw HTML

Count the words and links available in the original HTML response without JavaScript.

AI bot access

See whether robots.txt allows or blocks the named AI crawlers we check, including GPTBot.

Render mode

Get a diagnosis of server-rendered, partially rendered, or client-only content from the two page fetches.

Which AI crawlers we check

The checker reviews robots.txt rules for about 16 named AI bots. It shows which bots are allowed or blocked and separates direct crawlers from mediated access.

GPTBot

A bot used to collect web content for model training. The report shows whether robots.txt allows or blocks GPTBot.
