install questions, answered plainly.
Does tokcount need an account?
No. Install it and use it locally. The extension does not require sign-up or any prompt upload to show a live count.
Does my prompt text leave the browser?
No. tokcount is built to keep the counting inside the browser. It is a local helper for prompt length and cost estimation, not a remote analysis service.
Which browsers work?
Chrome, Firefox, and Edge all have install paths. If you use a Chromium browser such as Brave or Opera, the Chrome store link is the quickest route.
