What you'll get

Here's what a result looks like

An example verdict. Your result reads the raw HTML your homepage actually returns to AI crawlers.

Why it matters

AI crawlers read the raw HTML your server returns. They do not run JavaScript, so anything painted after scripts load can be invisible to them.

When someone asks ChatGPT, Claude, or Perplexity about your industry, those tools draw on what their crawlers were able to read. If your content only appears after JavaScript runs, or your robots rules block an AI bot, the page can be a blank to them even though it looks fine in a browser.

This check looks at exactly what those crawlers receive: whether your content is in the HTML, whether your structured data is valid, whether your headings and entity signals are clear, and whether your robots rules accidentally shut an AI bot out.

It is deterministic. There is no model guessing what AI "thinks" of your site. It reports readability facts you can act on.

Frequently asked questions

What is AI readability?

AI readability is whether an AI crawler, such as GPTBot or ClaudeBot, can parse the content of your page from the raw HTML it receives. If your important content is present in that HTML with clear structure, it is readable. If it only appears after JavaScript runs, or a robots rule blocks the bot, it may not be.

Do AI crawlers really not run JavaScript?

The major AI crawlers fetch your raw HTML and generally do not execute client-side JavaScript the way a browser does. Content that is rendered only after scripts run can be missing from what they read. Server-rendered or static HTML is the reliable way to make content available to them.

What is llms.txt?

llms.txt is an emerging, optional convention: a plain-text file at the root of your site that gives AI tools a curated map of your key content, a little like robots.txt does for search crawlers. This check detects whether you have one. It is not required, and its absence is treated as an optional gap, not a failure.

Is this the same as SEO?

It overlaps but is not the same. Traditional SEO focuses on ranking in search results. AI readability focuses on whether AI tools can parse your content at all. Some fixes help both, such as server-rendered content and valid structured data, but they are separate goals.

Does a good result mean AI will cite me?

No. Readability is necessary but not sufficient. A good result means AI crawlers can read your page. It does not guarantee any AI tool will mention or cite you, which depends on relevance, authority, and factors outside a single page. This tool reports readability facts, not visibility predictions.
