The problem

Open conversations, temporary files, system state, and small obligations live in different places and disappear the moment attention moves.

What I built

A local macOS companion that opens from the notch into windows, conversation memory cards, a file shelf, system stats, calendar, clipboard history, and local Ollama chat with optional screen vision.

Proof

Runs locally on macOS 14+, with deterministic tests for transcript parsing and conversation status.

What I learned

The best ambient tool stays invisible until the exact moment you reach for it.

Native macOS systems work across accessibility, local models, files, windows, and honest state derivation.
