Free MacBook notch monitor for Claude Code, Codex, and other AI coding agents
See at a glance which of your AI coding sessions are working, which need you, and which finished, with stable identities across CLI and desktop threads.
Click a row in the notch to jump back to the precise Claude Code or Codex session and thread, instead of hunting through terminals and windows.
Review permission requests and structured MCP elicitation forms from the notch; simple choices resolve inline while typed or secret fields open a native form.
Cover your displays with a private nap screen while builds and downloads continue in the background, with keep-awake holding off sleep and the lock timer.
