Quick answer
Install UsageAtlas on Windows 10 or 11 and it reads the Codex CLI you already signed in to. The tray shows how much of the five-hour and weekly windows is left, when each resets, and your credit balance. History keeps Codex tokens by day, model, and project.
Set it up
- Download the Windows installer from the download section.
- Run it. Choose More info, then Run anyway at the SmartScreen prompt, because the build is not code-signed yet.
- Make sure the Codex CLI is signed in with your ChatGPT account.
- Open UsageAtlas. Codex shows its windows and credits.
What you see
- Five-hour and weekly windows as percentages, with reset times.
- Your Codex credit balance.
- Tokens by day, model, project, and session from Codex's local logs.
- An alert when a window drops to the level you set.
