Score: 6.5/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 5)

Codenotch (CoIsland) is a macOS app that displays usage limits and status of various coding assistants (Claude Code, Cursor, Codex, etc.) in a small notch pinned to the screen edge. It aggregates data from many providers by borrowing local credentials and sessions, and also offers a phone companion app for remote monitoring. The project is interesting for its wide provider support and clever use of existing authentication mechanisms.

Target audience: developers using multiple AI coding assistants
