FAQ

What information does a User-Agent header provide?

A User-Agent string informs web servers about your browser application, rendering engine (Blink, WebKit, Gecko), client operating system, and hardware platform.

How are web crawlers and AI bots identified?

Search engine robots and AI crawlers (such as Googlebot, Bingbot, ChatGPT-User, and ClaudeBot) include distinct identifier tokens which this tool highlights instantly.

Is my personal browsing signature sent to a server?

No. The entire User-Agent parsing and environment capability detection run locally inside your web browser. No telemetry or signatures are transmitted.
