AI Usage Tracker Chrome Extension — Count Your AI Chat Usage
Always know how close you are to a rate limit before it interrupts you. AI Usage Tracker quietly counts the messages you send on the major AI chat assistants and shows a running tally in your toolbar.
Works on the major AI chats
Counts your messages on Claude, ChatGPT, Gemini and about a dozen other assistants.
Local, private counting
All counting happens in your browser — no account, nothing sent to a server, no page content stored.
Rate-limit awareness
See your running tally so you can pace usage and avoid hitting a limit mid-task.
Zero setup
Install, pin, and it just works in the background.
