Track AI usage without a Mac app (Windows & Linux)
Check connected Claude and Codex accounts in a browser on Windows, Linux, macOS or your phone, with manual refresh and a compact saved-reading view.
Updated September 6, 2026
If you move between a desktop and a phone, a browser view can be a useful place to check your connected accounts. You do not need a Mac-specific menu-bar app to use How Much Usage.
Open the dashboard where you work
Sign in from a browser on Windows, Linux, macOS or your phone. Press Refresh all when you want a usage check, then compare Claude and Codex accounts within their own providers.
Keep a compact view nearby
The web widget shows saved readings. On supported desktop browsers, Keep beside me opens a floating view. On a phone, a home-screen shortcut can open the compact web app when your browser offers it. This is not a native phone widget.
Know when the reading changed
Opening the widget does not query the provider. Refresh on the dashboard, then choose Reload saved reading in the widget. The age label helps you judge the snapshot; countdowns alone do not confirm that capacity has returned.
How Much Usage brings connected Claude and Codex accounts together. One account is free; unlimited connected accounts cost $15 once. For Claude alone, How Much Claude is $9 once, with one account free. These purchases do not increase your provider allowances.
Frequently asked questions

- Yes. The dashboard works in a browser. Floating-window availability depends on browser support.
- Do I need to install a native app?
- No native app is required for the dashboard or compact web view. Provider connection may involve a CLI command; follow the selected account’s connection instructions.
