Claude Usage Deck

Monitor your Claude.ai usage limits at a glance — badge shows weekly usage %, popup shows all metrics with countdowns.

Stop navigating to Settings every time you want to check your Claude.ai limits. Claude Usage Deck shows your usage right in the browser toolbar — color-coded badge icon, countdown timer, and a clean popup with all three metrics. ━━━ WHAT YOU SEE ━━━ 🔵 Badge icon — adaptive design: • Small sizes: solid colored circle (green / amber / red) • Large sizes: ring showing usage % with number in center • Badge text: time until reset ("2h", "45m", "3d") 📊 Popup dashboard: • Status summary — instant "Safe / Moderate / High" for each metric • Session (5h) — current session utilization + countdown • Weekly All Models (7d) — combined usage across all models • Sonnet (7d) — Sonnet model tracked separately • Progress bars color-coded: green (0-49%), amber (50-79%), red (80-100%) ━━━ FEATURES ━━━ • Window Anchor Insight — see when your 5h session window started and when it resets. Pro tip: send a quick "hi" early to anchor your window to a predictable schedule. • Badge metric selector — choose which metric the toolbar icon shows (Session / Weekly / Sonnet). • Light & dark theme — follows your browser/OS preference automatically. • Auto-refresh every 5 minutes + manual refresh button. ━━━ PRIVACY ━━━ • No analytics, no tracking, no accounts • No external servers — only talks to claude.ai • All data stored locally in your browser • Open source (MIT) — read every line on GitHub ━━━ HOW IT WORKS ━━━ The extension polls claude.ai/api/organizations/{org_id}/usage every 5 minutes using your existing browser cookies.
