See your pagethe way ChatGPT does.

34% of the 379 homepages we checked send fewer than 500 words before JavaScript runs, and 17% fewer than 200. Most AI crawlers never run it. Enter a page to see exactly what they get.

Why it matters

900Mpeople use ChatGPT every week. OpenAI via TechCrunch, 2026. Its crawler reads the raw HTML.
17%of 379 homepages we scanned send under 200 words: close to blank for an AI answer, however good they look.

what this tool can't do

This shows one of the sixteen checks. The audit covers the rest.

A readable page is where AI search starts. Whether ChatGPT names you over a competitor depends on the other fifteen checks, your other pages and what other sites say about you. That is what our AEO and GEO audit covers, and we make the fixes, including moving a JavaScript-only site to one that renders on the server.

Questions

Why would ChatGPT see a different page from my visitors?

Browsers run your JavaScript; most AI crawlers do not. Vercel’s study of its network found none of the major AI crawlers rendered JavaScript, including OpenAI’s and Anthropic’s (December 2024). If your words are drawn by JavaScript, those crawlers get the empty shell.

Does Google see it the same way?

No. Googlebot runs JavaScript, and Gemini uses Google’s crawling. ChatGPT, Claude and Perplexity are the ones that read the raw HTML.

How do I fix a blank page?

Send the words in the HTML: render the page on the server or as static HTML (Next.js, Astro, Framer and Webflow all can), and put one plain paragraph near the top that says what you do, for whom and from what price.

Is this tool free?

Yes, with no sign-up. We fetch the one page you enter, keep the result for ten minutes and store nothing else.
