Whether there is text to read
A page built by a script can arrive as an empty shell. We count the words in the raw HTML and say plainly when there are almost none.

Most AI crawlers read the HTML your server sends and never run JavaScript. Enter a page and see what is left: its title, description, headings, links and text, with anything missing called out.
A page built by a script can arrive as an empty shell. We count the words in the raw HTML and say plainly when there are almost none.
Title, meta description, canonical link, a single H1, image alt text and any noindex rule, each shown as present or missing.
The internal and external links a crawler can follow from the page, and the address it landed on after redirects.
We request the page once from our servers without running JavaScript, follow its redirects, and read the HTML that comes back. Nothing is scored: each item is either there or it is not.
The HTML your server sends, and nothing JavaScript adds afterwards. Most AI crawlers do not run JavaScript, so text a script paints in is text they never read. This tool fetches your page once without running any and shows what is left: title, description, headings, links and a sample of the text.
The raw HTML carries almost no readable text, so the page is a shell a script fills in. Visitors see a normal page; a crawler that does not run JavaScript sees next to nothing. Rendering the text on the server, or prerendering the page, fixes it.
Google renders JavaScript, so it usually sees more. The gap between the two is what this tool shows: the page as the crawlers that do not render it read it.
This reads one page, raw. The AI visibility check reads up to ten pages of a site and scores fourteen signals, including whether AI crawlers are allowed in at all.
