I built TokenBar after realizing I had no idea what my prompts were costing

I kept testing prompts across Claude and ChatGPT, then checking usage later and realizing I had basically no feel for where the tokens were going.

That was the whole reason I built TokenBar for Mac. It sits in the menu bar and shows token usage in real time, so I can see when a prompt, retry, or long context window is about to turn into an expensive habit.

It is not a finance dashboard or team analytics tool. It is just a simple way to make AI usage visible while you work.

If you are building with LLMs every day, I am curious: do you track token usage live, or only after the bill shows up?
