Claude Account Switcher

⸻

📊 FULL USAGE DASHBOARD

Monitor your Claude usage directly in the extension popup:

• 5-hour session gauge — see what percentage of your current session limit is used and when it resets.
• 7-day weekly cap — track your rolling weekly usage across all models.
• Per-model breakdown — individual usage bars for Opus, Sonnet, Haiku, and Claude Design.
• Daily routines tracker — monitor how many of your daily routines you have used.
• Plan detection — automatically detects your Claude plan (Free, Pro, Max 5x, Max 20x, Team, Enterprise) and displays it as a badge.
• Reset countdowns — see exactly when each limit resets in hours and minutes.
• Collapsible panel — expand or collapse the dashboard; your preference is remembered.

⏱️ PEAK HOURS MONITOR

Know when Claude usage is busiest so you can plan your work:

• Detects whether you are currently in peak hours (weekdays 5 AM – 11 AM Pacific Time).
• Displays a countdown to the next peak/off-peak transition.
• Notes when Claude Code usage is counted separately (Pro and Max plans).

⸻

📈 30-DAY USAGE HEATMAP

Understand your Claude usage patterns over time:

• Visual hourly heatmap showing your Claude activity over the past 30 days.
• Color-coded intensity from idle to heavy use.
• Broken down by day of week and hour.

⸻

📉 IN-PAGE USAGE PROGRESS BAR

See your usage limit directly on the Claude.ai page:

• A subtle progress bar injected at the top of Claude.ai showing your current usage percentage.
• Color-coded: green (low), orange (medium), red (approaching limit).
• Updates automatically every 10 seconds with live data.
• Toggle it on or off from the extension popup settings.
• Appears alongside the Claude.ai interface without disrupting your workflow.

👤 PROFILE MANAGEMENT

Organize your saved Claude accounts:

• Store up to 5 account profiles locally.
• Custom profile names up to 40 characters.
• Color-coded avatars — five distinct colors for quick visual identification.
• Inline renaming — click a profile name to edit it directly.
• Two-step delete confirmation — prevents accidental deletion.
• Automatic email detection — shows the detected email address for each saved account.
• Stale profile badge — alerts you when the cookies for a saved profile have expired and need refreshing.
• Profiles sorted by most recently saved.
• Relative save dates displayed (e.g., "today", "yesterday", "3 days ago").

⸻

📤 IMPORT & EXPORT PROFILES

Back up or transfer your saved profiles:

• Export all saved profiles as a dated JSON file.
• Import profiles from a previously exported file.
• Useful when migrating to a new computer or restoring from a backup.
• Exported files contain session cookies — keep them private and treat them like credentials.

🎨 THEME SUPPORT

• Light mode, dark mode, or auto (follows your system preference).
• Switch themes from the popup header.
• Warm Claude-inspired design with parchment surfaces, terracotta accents, and ivory tones.

⸻

🛡️ PRIVACY & SECURITY

Claude Account Switcher is built with a local-first, least-privilege security model:

• All saved profiles are stored locally in your browser using chrome.storage.local. Nothing is sent to any server.
• Cookie operations are limited to https://claude.ai/* — the extension cannot access cookies from other sites.
• Only three permissions requested: cookies, storage, and tabs. No broad host permissions, no webRequest, no <all_urls>.
• Background-only cookie access — all cookie operations run in the Manifest V3 service worker. The popup cannot access cookies directly.
• Storage hardening — on supported browsers, storage access is restricted to trusted extension contexts.
• No analytics, no telemetry, no tracking. Your data stays on your device.
• The only content script injected is the optional usage progress bar on claude.ai.

Saved profiles include Claude session cookies. Treat saved profiles like credentials and only install the extension in browser profiles you trust.

🌐 BROWSER COMPATIBILITY

Works on all Chromium-based browsers that support Manifest V3:

💡 WHO IS THIS FOR?

Claude Account Switcher is designed for power users who:

• Use separate Claude.ai accounts for personal projects, work, different clients, or teams.
• Want to avoid the repetitive log-out-and-log-in cycle every time they switch contexts.
• Need to monitor their Claude usage limits across sessions and models.
• Work across multiple Claude organizations or workspaces.
• Want a faster, cleaner multi-account workflow without using multiple browser profiles.

⸻

Claude.ai does not include a built-in account switcher. If you manage more than one Claude account, this extension makes switching seamless.
