Claude Usage Monitor

About

Claude Usage Monitor is a Chrome extension that helps users understand and manage their claude.ai usage.

The extension periodically retrieves usage information from claude.ai while the user is logged in, stores usage snapshots locally in the browser, and displays the data in an easy-to-read dashboard. Users can check usage for each organization, view remaining usage and reset timing, switch between light and dark themes, and open a full visualization page for more detailed analysis.

Key features:
* Track claude.ai usage for each organization
* Display 5-hour and 7-day usage windows
* Show remaining usage, utilization rate, and reset timing
* Automatically update usage data in the background
* Manually refresh usage data from the popup
* Visualize historical usage with charts
* Filter chart ranges by 24 hours, this week, last week, this month, last month, or all time
* Change chart granularity by 15 minutes, hourly, daily, or monthly
* Export locally stored usage data as JSON
* Open exported JSON files for read-only visualization
* Switch between light and dark themes

This extension is designed only for monitoring and visualizing the user’s own claude.ai usage. It does not provide automation for sending messages, bypassing usage limits, modifying claude.ai behavior, or accessing unrelated websites.

Usage data is stored locally in the user’s browser using Chrome storage. The extension does not sell user data, does not use the data for advertising, and does not share the data with third parties. JSON export is initiated by the user, and exported files are saved by the user for their own use.

Please note that this extension relies on claude.ai internal endpoints that may change without notice. The user must be logged in to claude.ai for usage data retrieval to work.
