Your browser is
telling on you.

You did not click anything. You did not grant a permission. Yet the moment this page loaded, your browser handed over everything below, the same way it does for every site you have ever visited. Here is what leaks, and the fingerprint they build from it. None of it leaves this page.

// same x-ray, pointed at your website
That is what your browser leaks. Do you know what your website hides?

Same idea, aimed the other way. AI crawlers don't execute JavaScript, so the version of your site ChatGPT reads can be radically thinner than the one you just looked at. The AI Visibility Audit reads your site the way those crawlers do and shows you the difference.

What your browser reveals

Browser X-ray reads what your browser hands over the moment a page loads, then shows it back to you in four groups.

Fingerprinting is not cookies

Cookies are files a site stores on your device. You can see them, delete them, or block them in one setting. A fingerprint works differently: it is calculated from traits your browser exposes anyway (screen size, fonts, GPU, timezone, and the rest), so there is no file to clear and no setting that removes it. It even works in private or incognito mode, since those traits do not change just because the window is private.

This tool reads those values only to display them to you, in your own browser. Nothing is sent to a server, logged, or stored anywhere.

Frequently asked questions

What does Browser X-ray show?

It shows everything your browser exposes to any site you visit, IP, user agent, screen size, language, timezone, WebGL and canvas fingerprints, fonts, and permissions, plus a derived fingerprint.

Does the tool send my data anywhere?

No. It runs entirely in your browser and sends nothing to a server. The point is to show you the exposure, not collect it.

What is the difference between cookies and fingerprinting?

Cookies are files a site stores that you can clear. Fingerprinting derives an identifier from your browser's characteristics, screen, fonts, GPU, which you can't simply delete, and it works even in private mode.

This runs entirely in your browser. Nothing is sent anywhere, logged, or stored. Your IP and rough location go to every server you talk to as well, but this page never even asks for them, because that is the whole point.
