Mochi watches your AI agent so you don't have to

A tiny character lives in your Mac's notch and keeps an eye on your AI coding sessions — alerting you the moment something needs your approval.

A small guardian in an easy-to-miss place

Your MacBook has that little pill-shaped cutout at the top of the screen — the notch. Most apps ignore it. Coucou puts a tiny animated character called Mochi right there.

Mochi's job is simple: watch what your AI assistant is doing and tell you about it. If you use Claude Code or a similar tool to help write or edit files, those sessions run quietly in a terminal window you've probably minimized and forgotten. Mochi keeps an eye on all of it — every file opened, every change made — and shows you a little live summary without you having to go looking.

The part that caught my attention: when the AI needs permission to do something — say, run a command or touch a sensitive file — a small Allow / Deny button appears right in the notch. No hunting for the terminal. No missing a critical moment because you were in another tab.

It works on Windows and Linux too, just as a small bar at the top of your screen instead of the notch.

It's free, open source, and built with privacy in mind — no account to create, no data sent anywhere, your API keys stay on your own machine.

Words worth knowing

AI coding agent — a tool like Claude Code that can read, write, and run files on your computer on your behalf, following instructions you give in plain language.

Open source — the code is public and free for anyone to inspect, use, or improve.

Notch — the small cutout at the top of newer MacBook screens that houses the camera.

Telemetry — data an app quietly sends home about how you use it. Coucou sends none.

If you already let an AI assistant touch your files, it's worth knowing what it's actually doing in there. Mochi makes that visible with almost no effort on your part.
