Coucou

A tiny friend that lives in your notch

Coucou watches your AI coding agents — Claude Code, Codex, Cursor, Gemini CLI, Antigravity, Hermes and more — lets you approve Claude Code and Codex requests from the notch, chat with Anthropic, Google AI or OpenAI, keeps an eye on Stripe, GitHub, Vercel, n8n and more, and follows you to your iPhone. New in 0.4 on Mac and 0.5 on Windows and Linux: Coucou becomes an app, with Flow dictation anywhere, the Notetaker for your calls and « OK Coucou » to talk to Mochi. Free and open source.

Coucou is free and open source.
If it saves you time, you can buy Mochi a coffee.

Dictation, notes and your voice

Coucou now has its own window, on the Mac, Windows and Linux, with everything it does in one place.

• Flow dictation: hold a key anywhere, speak, let go: your words are pasted where you type. Two taps for hands-free, a dictionary, snippets, a style per app and your statistics.
• Parakeet, on your computer: NVIDIA’s speech recognition runs offline, in 25 languages. Downloaded once, only when you click Download.
• Notetaker: record a call (no bot joins it) and get the transcript person by person, with a summary and the to-dos. The audio is deleted once the transcript is written.
• « OK Coucou »: say it and ask anything: add a pill, play music, your Stripe sales, the weather, an email to prepare. Claude answers with your own key; your voice never leaves your computer.

Now on iPhone

Step away from your Mac and Mochi follows you. The iPhone app goes as far into the Apple ecosystem as a dev tool can:

• Live Activity and Dynamic Island: lock your Mac while an agent works and Mochi moves to your Lock Screen. Allow or Deny a permission right from there.
• Notifications you can act on: Allow, Deny, pick an answer to Claude’s question, or reply to a finished agent.
• Face ID on every Allow: nothing runs on your Mac without your explicit tap.
• Talk to your agents: follow each session live, read the diffs, send the next instruction by text or voice.
• Widgets, Control Center, Siri, Shortcuts, Spotlight and Focus filters.
• Your services up close: GitHub, Vercel, Stripe, Cal.com, n8n, Notion and Resend, with safe actions like re-running CI or redeploying.
• Through your own iCloud: no Coucou server sees your projects, commands or keys.

Coming to the Mac App Store and the App Store: one click to install, automatic updates, and the iPhone pairs with your Mac through iCloud. Until then, download the Mac app from GitHub.

Now on Android

Coucou for Android puts Mochi on your Android phone, linked to Coucou on your Windows or Linux computer over your Wi-Fi.

• Allow or Deny from your phone, even locked: a request wakes the screen; notifications show at most the tool and the program’s name, never the full command. Allow asks for your fingerprint or screen lock; Deny doesn’t.
• Your agents at a glance: Mochi shows who is working, plan usage and your services.
• Answers and chat: answer Claude Code’s questions and chat through your computer’s own AI keys, when you turn them on there.
• An island over other apps (optional), a widget, a quick-settings tile and a notification that keeps the link alive.
• Local and private: the phone talks straight to your computer on your Wi-Fi, paired with a QR code and a pinned certificate. The phone link is off by default.
• Free, no ads, no analytics.

Needs Coucou 0.4.0 or later on Windows or Linux (not the Mac), Android 11 or later, and both on the same Wi-Fi.

Download the Android appHow to set it up

Requires macOS 15 or later. No notch? Mochi sits in a small bar at the top of the screen. Windows 10/11: the button downloads the .msi installer; prefer an .exe? Here it is. Not signed yet, so SmartScreen may ask: click More info → Run anyway. Linux: version 0.5 is out (AppImage, .deb, .rpm), download it here.
