I built a macOS menu bar token meter for AI work

I kept noticing that AI spend gets harder to control once a chat is already bloated with stale context, retries, and oversized model choices.

So I built TokenBar: a tiny macOS menu bar app that shows live token usage while you work, not after the bill arrives.

It is mostly for builders using LLMs all day who want an in-session signal for when to restart, trim context, or switch models.
