About

Coucou

Features
Read full description

Coucou is the iPhone companion of Coucou for Mac, the little friend who lives in your MacBook's notch and keeps an eye on your AI coding agents: Claude Code, Cursor and the Claude desktop app. SEE YOUR SESSIONS Every agent session from your Mac, live: what it's doing, its plan step by step, its last message. The most urgent one first. Several sessions in the same project each get their own row, with their real title. ANSWER FROM ANYWHERE When an agent needs your permission, you get a notification with the exact command. Deny it right from the notification, or allow it with Face ID. When several sessions ask at once, each question and request gets its own card, and you answer them one by one. Your Mac only applies a decision meant for the exact request it is waiting on, and requests expire after 2 minutes. MOCHI IN YOUR DYNAMIC ISLAND Lock your Mac while an agent works: Mochi moves to your iPhone's Lock Screen and Dynamic Island, and comes back to the notch when you unlock. WIDGETS Solo, Team and List on the Home Screen, and Mochi on the Lock Screen, in the colours you picked for each Mochi on your Mac. PRIVATE BY DESIGN No account, no analytics, no ads. Your sessions travel through your own private iCloud, with project names, commands and questions encrypted with your iCloud keys. Requires Coucou for Mac with Settings โ†’ General โ†’ iPhone turned on, and the same Apple Account on both devices.
