Free tool
See what an AI sees on your website.
ChatGPT, Claude, Perplexity and Google’s ad-quality crawler mostly do not run JavaScript. This fetches your homepage the same way and shows you exactly what comes back. No sign-up, no email.
Why this matters
We crawled 1,348 companies that had just raised funding and found that 8.7% serve a page like this — the median one returning 55 characters where the rendered page had 5,358. Counter-intuitively, sites on modern JavaScript frameworks were the worst affected and sites on Wix and Squarespace were the best. Read the study.
- What does this tool actually do?
- It requests your homepage the way a crawler that does not run JavaScript would, and shows you exactly what came back — the readable text, the title, the H1, the meta description and any tags visible in the source.
- Why does JavaScript matter for AI search?
- Assistants such as ChatGPT, Claude and Perplexity, and Google’s ad-quality crawler, generally do not execute JavaScript. If your page builds its content in the browser, they receive an almost empty document no matter how good the page looks to a person.
- My site looks fine but the tool says it is empty. Is it broken?
- Not for human visitors — it will look completely normal. It means the content is assembled in the browser rather than sent by the server. The fix is server rendering or prerendering, which is usually a configuration change rather than a rebuild.
