What you get

  • Per-conversation counter Estimated context length, messages remaining, and prompt cache status next to the chat title.
  • Desktop notifications Heads-up at 90% utilisation and a confirmation when a window resets.
  • VS Code companion Same quota visible in your editor status bar, kept in sync with the Chrome extension.
  • Reads the same data Claude does Uses claude.ai's own internal APIs. No API key required.

See it in action

Five views, one extension. Every screenshot taken from the live product.

Sidebar widget with all five quota windows (Session, Weekly, Sonnet, Design, Extra usage) sitting quietly next to your chats.
One click on the toolbar icon opens the full breakdown: every window, 7-day chart, daily averages.
Hover any row to see exact tokens used, hourly burn rate, and a 7-day chart of your daily peaks.
Bottom bar in the chat input. A single line, two windows, one click to token-saving tips.
Compact view with the "messages remaining" estimate, tuned to the average size of your own messages.

Private by design

The extension does not have a backend. It does not talk to any third party. It does not run analytics.

Quota data is read from the same Server-Sent Events and JSON endpoints that claude.ai already exchanges with Anthropic. Everything is stored locally in your browser profile via chrome.storage.local and never leaves your device.

No conversation content, no chat titles, no usernames, no email addresses, no API keys. The optional VS Code companion communicates over a local HTTP bridge on your own machine, on loopback only.
