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.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
