Claude Usage Monitor is a free Chrome extension designed to help users track their Claude.ai usage effectively. It features a user-friendly dashboard that displays usage statistics over various time periods, including 5-hour and 7-day limits. The extension visualizes data through donut charts and progress bars, providing a clear overview of usage patterns. Additionally, it updates automatically every five minutes, ensuring users have access to the most current information. Users can customize the layout of the dashboard to suit their preferences, choosing between one, two, or four columns.

One of the standout features is the pace indicator, which displays a purple line to show expected usage relative to the elapsed time. This helpful visual cue allows users to quickly assess whether they are consuming credits faster or slower than average. To set up the extension, users simply need to enter their Claude.ai Organization ID, which can be easily found in the account settings. Importantly, all data is stored locally on the device, enhancing user privacy while utilizing this unofficial tool.
