Diet Claude is a free Chrome extension that displays a live usage meter for Claude AI, visualized as a soda can that drains as you consume your session and refills when the limit resets. It shows how much of your 5-hour session and weekly allowance you have used, how much time remains, and when limits reset. The extension also helps optimize token usage through context trimming, prompt tightening, and model suggestions. When limits are reached, it can carry your conversation and context over to an alternative LLM so work is not lost.
