How it works

  1. 01

    Install the extension

    Add it from the Chrome Web Store or load unpacked from GitHub. The extension fetches your org ID automatically on first run.

  2. 02

    Glance at the badge

    The toolbar icon shows your usage at a glance — color indicates status (green / amber / red), badge text shows time until reset.

  3. 03

    Click for details

    The popup shows all three metrics with progress bars, countdowns, and a status summary. Pick which metric the badge displays.

Features

  • Adaptive badge icon

    Solid colored circle at 16px for instant status recognition. Ring with percentage number at 32px+ for detail.

  • Countdown badge

    Badge text shows time until reset — "45m", "2h", "3d". Always readable, rendered by Chrome natively.

  • Status summary

    Quick decision support at the top: Session Safe, Weekly High, Sonnet Safe. Know instantly if you can keep working.

  • Three metrics

    Session (5h window), Weekly All Models (7d), and Weekly Sonnet (7d) — each with progress bar, percentage, and countdown.

  • Window Anchor Insight

    See when your 5h session window started and when it resets. Power tip: anchor your window early with a quick Haiku message.

  • Badge metric selector

    Choose which metric the toolbar icon displays — Session, Weekly, or Sonnet. Setting persists across browser restarts.

  • Color-coded status

    Green (0–49%), amber (50–79%), red (80–100%). Applied to progress bars, badge icon, and status dots.

  • Light & dark theme

    Follows your browser preference automatically. Both themes carefully designed for readability and visual comfort.

  • Zero tracking

    No analytics, no accounts, no external servers. Data flows from claude.ai to your browser. All stored locally.

Pro tip: Window Anchor

Your 5-hour usage window starts when you send your first message, floored to the clock hour. If you send a quick "hi" using Haiku at 6:00 AM, your window anchors to 6:00–11:00 AM — even if you don't start real work until 8 AM.

This gives you a predictable reset schedule instead of having the window start mid-morning when you're deep in work. Claude Usage Deck shows this window right in the Session metric card.
