🧩

◌

5-hour usage ring

See the current short-window Claude usage percentage in the popup and on the toolbar icon at a glance.

▰

7-day usage bar

Check the longer weekly window from the same popup, including a reset estimate when Claude provides it.

⟳

Refresh on demand

Click the refresh button whenever you want a fresh reading instead of waiting for the next background update.

☁

Quiet background updates

The toolbar ring refreshes periodically so the last displayed status stays useful without opening the popup.

🔐

No separate account

The extension uses your existing signed-in claude.ai session. There is no Notavello login or external service.

Designed to answer one question quickly.

When you are planning a long work session, the last thing you want is a surprise usage wall. Usage Meter for Claude keeps the key numbers close by: the current 5-hour window, the 7-day window, and reset timing if it is available.

  • Small toolbar popup with a familiar dark interface.
  • At-a-glance color changes as usage gets higher.
  • Works from the Chrome toolbar while you stay signed in at claude.ai.

Privacy-forward by default.

The extension does not run a Notavello server, does not sell data, and does not collect prompts, answers, or chat content. It only requests access to claude.ai so it can read the usage-limit information shown to your own account.

Unofficial companion

Usage Meter for Claude is not affiliated with, endorsed by, or sponsored by Anthropic. It may stop working if Claude changes the usage endpoint.

  • No prompts, chats, or message content collected.
  • No third-party analytics inside the extension.
  • Usage state is kept locally in Chrome storage.

Simple workflow
