AI usage rings in your Mac's notch, with the math shown
Rings beside the MacBook notch for Claude Code, Codex, Cursor, Gemini CLI and GitHub Copilot: used share, pace tick, run-out projection, reset time, cost from local transcripts, and an Advice strip that says what to do next. Free, MIT, never signs in.
Notchmeter is a developer tool for Mac that displays AI usage metrics alongside the MacBook notch, integrating with tools like Claude Code and GitHub Copilot. It is open-source under the MIT license and does not require user sign-in.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
