Claude Usage Bar: Track Your Claude.ai Usage in Chat

*UPDATE: you can now choose your design in Settings. Pick the classic bar under the chat, or the new compact widget that sits in the composer toolbar, whichever you like best. Claude Usage Bar shows how much of your Claude.ai usage you have left, right under the chat box, so a limit never catches you off guard mid-conversation. It puts small bars under the message box for your current 5-hour session usage and your weekly all-models usage. If your plan has a separate Opus allowance, that appears too. Each bar is color-coded, blue when you are under 30%, orange from 30% to 80%, and red above 80%, and it shows a countdown to when the limit resets. New in this version, you can choose between two designs in Settings. Design 1 is the full-width bar under the chat box, the original look. Design 2 is a compact version that tucks into the composer toolbar, between the plus button and the model picker, showing your session as a small bar and your weekly limits as rings. Design 1 stays the default, so nothing changes unless you want it to. There is nothing to set up. No tokens, no API keys, and no extra sign-in. As long as you are logged in to Claude, it just works, because it reads your usage straight from Claude using the session already in your browser. Everything stays on your device and nothing is sent to any server. You can pick which bars show, turn the bar on or off with a keyboard shortcut, and open a small popup for the same numbers with a one-click refresh. Your privacy is respected. The extension only talks to claude.ai and keeps your numbers in your local browser storage. It never reads your conversations and never sends your data anywhere.
