Can AI actually read your website?
AI crawlers like GPTBot, ClaudeBot and PerplexityBot don't run JavaScript. Many modern sites show them an empty shell — your content exists, but AI can't see it. Enter your address and get the answer in 10 seconds.
We fetch your page exactly like an AI crawler does — without JavaScript. Nothing is stored, no login.

Why AI readability matters
If AI can't read your site, it can't recommend you either.
AI crawlers don't run JavaScript
Running a headless browser on every single page is too expensive at scale. So GPTBot (ChatGPT), ClaudeBot and PerplexityBot only read your raw HTML. If your content lives in JavaScript, they see an empty page.
Modern site builders are especially exposed
Sites built with e.g. Lovable, Bolt, v0 and Replit are often client-side rendered: the HTML contains only <div id="root"></div>, and all content is loaded with JavaScript afterwards. A human sees a beautiful page — AI sees nothing.
robots.txt can block you by accident
Many sites block AI crawlers in robots.txt without knowing it — often because a template or plugin did it automatically. Then you're invisible in AI no matter how good your content is.
Readability is step 1 — visibility is step 2
First, AI must be able to read you. Then it must be able to find, understand and recommend you — that takes structured data, llms.txt and a strong brand entity. The free GEO test measures both across 15 dimensions.
Frequently Asked Questions
Why can't AI read my website?
AI crawlers normally don't run JavaScript. If your site is client-side rendered, the content lives in JavaScript bundles and the crawler only sees an empty HTML shell. Your content exists — AI just can't see it.
What does the AI Readability Check test?
We fetch your page without running JavaScript and measure the readable text. We also check robots.txt (are you blocking GPTBot, ClaudeBot or PerplexityBot?), llms.txt, structured data (schema.org), the H1 heading and meta description — and detect which tool the site was built with.
Does it cost anything?
No. The tool is free and requires no registration. Enter your address and get the answer right away.
My site is readable — why does AI still not mention me?
Readability is only step 1. Step 2 is visibility: being found, understood and recommended by AI. The free GEO test measures that across 15 dimensions — including brand entity, structured data and third-party validation.
Want to know if AI recommends you too?
Readability is the foundation. The GEO test measures your full AI visibility — free, in 60 seconds.
