Are you a real browser —
or a bot?
The check below runs the moment this page loads. It reads around two hundred things about your browser, your device and your connection — the same readings common bot-detection systems take — and explains every one of them in plain English.
Nothing is stored. Nothing is uploaded. Nothing asks you for permission.
Reading your browser…
Around two hundred readings, all of them ones any website can take without asking.
What the readings are for
Bot detection is the reason a page sometimes decides you are not a person. These readings are taken quietly by sites all over the web — your browser build, your screen, your fonts, your timezone, the shape of your connection — and what they add up to decides whether you get the page, a challenge, or nothing at all.
This tool takes the same readings on your own machine and tells you what each one says about you, in plain English. It runs in the tab you are sitting in and stops when you close it. Nothing is sent anywhere and nothing is kept.
Knowing what a site can see is a good way to understand why the open web is harder to read than it looks. That is the problem askFinz set out to solve. Rather than paying someone else for search results, askFinz reads the web itself and holds what it means, so a question is answered against something already read instead of a fresh fetch that may never get through. The web index sets out how that is done.
