Privacy details

User agent parser processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Optional settings apply only to this tab.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

User agent parser explained

Split a user-agent string into product/version tokens and platform comments. A clearly labeled heuristic highlights a familiar browser token while preserving the raw reported tokens for your own inspection.

A worked example

A string containing both Chrome/120.0 and Edg/120.0 highlights Edg, while still showing both tokens. This reflects the string, not independent proof of the installed browser.

Before you use the result

No device database is loaded and no identity is established. Modern browser privacy controls reduce version and platform detail; spoofed strings cannot be detected reliably from the string alone.
