SimpleClaudeUsage

SimpleClaudeUsage puts your Claude plan usage in the toolbar. Click the icon and you see, for every account you have added: - Session (5 hour) utilization, and when the window resets - Weekly utilization, including per-model limits when the API reports them - Extra usage credits: amount spent, monthly limit, percent used - Reset times shown as a countdown, with the exact local time on hover Built for people with more than one Claude organization. Add as many IDs as you want and every one gets its own card, refreshed in parallel each time you open the popup. HOW IT WORKS The extension reads one endpoint on claude.ai, the same one the site itself uses to draw your usage meters, using the session you are already signed in with. There is no account to create and nothing to configure beyond pasting your organization ID, which you copy from claude.ai → your name → Settings → Account. BUILT FOR A MOVING TARGET That endpoint is undocumented and its shape changes without notice, so the extension does not assume much. Limit types it has never seen still render. Missing fields are skipped instead of breaking the popup. Money is read from whichever field is present. And every card keeps a "Raw response" panel with the pretty-printed JSON, so when something looks wrong you can see exactly what the API returned. PRIVACY Your organization IDs and the most recent response are stored on your own device with Chrome's local storage. Nothing is sent to Northwest Nerds or anyone else — there is no server, no analytics, and no tracking. The only network request is to claude.ai. The extension has access to claude.ai only, and reads a single JSON endpoint on it. NOT AN ANTHROPIC PRODUCT SimpleClaudeUsage is an unofficial, independent extension from Northwest Nerds.
