AI usage Monitor

Tracks usage on Claude, Gemini and ChatGPT (Usage quotas) Track your AI usage across Claude, ChatGPT, and Gemini. AI Usage Monitor displays quota bars directly in your chat interface, showing your available usage percentages and reset times. Click the extension icon for a quick overview of all three services. Features:

• Session and weekly quota indicators, where available
• Integrated usage bars on claude.ai, chatgpt.com, and gemini.google.com
• A toolbar popup with usage summaries and reset times
• Background refresh from the popup, even with service tabs closed, while authentication remains valid
• Automatic updates while using the supported chat interfaces
• Light and dark theme support for the ChatGPT widget and popup

Privacy: The extension requests usage information directly from the supported services using your existing signed-in sessions. Quota summaries are stored locally in your browser. Authentication tokens needed for background refresh are kept in temporary browser-session memory. No data is sent to developer-operated servers. Open each service once to initialize access. You may need to reopen it after restarting your browser or when your session expires. This is an unofficial extension, not affiliated with Anthropic, OpenAI, or Google. Usage availability depends on your account and the data exposed by each service.
