AI readability check

Can AI enginesread your website?

Enter your domain. In about 30 seconds this AI visibility checker shows what the crawlers behind ChatGPT, Claude, Perplexity and Google find when they visit: whether they are allowed in, whether there is any text before JavaScript runs, and whether they can tell who you are.

We read only public pages: your homepage, robots.txt and sitemap. The domain you check is logged for 30 days to prevent abuse, and your connection's address is used only for a rate-limit counter that expires within hours.

What the check looks at, and why it matters

An AI engine can only name a business it can fetch, read and identify. Each check below is one way AI visibility breaks, in the order it usually matters.

Crawler access in robots.txt
ChatGPT search, Perplexity and Claude each send their own crawler, separate from the ones that collect training data. Blocking a training crawler such as GPTBot is a legitimate choice and does not remove you from AI answers. Blocking a search crawler does, and blocking Bingbot also takes you out of ChatGPT search, which runs on Bing's index. OpenAI documents its crawlers and what each is for here.
Text before JavaScript runs
A single-page app sends an empty page and fills it in with JavaScript in the browser. Googlebot runs that JavaScript; the crawlers behind ChatGPT, Claude and Perplexity do not. Vercel and MERJ analysed crawler traffic in December 2024 and found no JavaScript execution from those crawlers. A site built this way looks close to blank to them, however good it looks to you. The fix is server-side rendering or prerendering.
Open to indexing
A page carrying a noindex instruction is dropped from Google, and with it from AI Overviews and AI Mode. Google's own guidance is that a page must be indexed and eligible to show with a snippet before it can appear in any of its AI features.
Title, description and canonical
The title and description are the first description of the business an engine reads. The canonical tag tells it which address is the official one, so the www, non-www and trailing-slash copies of a page do not compete with each other.
A machine-readable identity
Structured data (an Organization or LocalBusiness block) states the business's name, address, logo and official profiles in a form engines read without guessing. It confirms who you are; on its own it is not a ranking boost.
A sitemap
A sitemap lists every page you want found. Without one, new pages depend on being discovered through links, which on a small site can take weeks.
A known entity
The check looks for a Wikidata item with your business's name. For a small business, not having one is normal. What matters more is that your name, address and phone match exactly across your site, your Google Business Profile and the business registers, so an engine can be sure every mention is you.
