Coucou

Overview

Coucou is a free, open-source companion app that lives in the Mac notch or at the top of the screen on Windows and Linux. It watches AI coding agent sessions, supports approvals and questions from the notch or a phone, provides AI chat with your own keys or subscription, offers dictation and call notes, and surfaces service integrations such as Stripe, GitHub, Vercel, and n8n. iPhone and Android companions extend sessions, approvals, widgets, and service views beyond the desktop.

Key Features

• Watches live sessions for Claude Code, Codex, Cursor, Gemini CLI, Antigravity, Hermes, and other agents, showing reads, edits, commands, and diffs.
• Approve or deny Claude Code and Codex permission requests from the notch, and answer Claude questions in the notch.
• Chat with Anthropic, Google AI, OpenAI, DeepSeek, Qwen, Moonshot, or local Ollama and LM Studio models using your own API keys or subscription.
• Flow dictation pastes speech into any app, with offline Parakeet speech recognition on Apple silicon, a dictionary, snippets, and per-app styles.
• Notetaker records calls without a bot joining, produces person-by-person transcripts, summaries, and to-dos, then deletes the audio after transcription.
• iPhone and Android companions show sessions, approvals, services, widgets, and remote actions.

Use Cases

• Monitor multiple AI coding agent sessions and approve permission requests while working elsewhere.
• Dictate text into any application and review local dictation statistics.
• Record and summarize calls with transcripts, key points, and action items.
• Keep up with Stripe, GitHub, Vercel, n8n, Notion, Cal.com, and Resend from the notch or phone.

Getting Started

• Download the Mac app from GitHub releases, or use the Windows .msi or .exe installer, or the Linux AppImage, .deb, or .rpm package.
• For iPhone, install Coucou via TestFlight and enable Settings → General → iPhone in the Mac app with the same Apple Account in iCloud.
• For Android, install the signed APK and use Coucou on Windows or Linux, with both devices on the same Wi-Fi.

• Windows 10/11 with an .msi or .exe installer.

Before You Adopt

• License: MIT. Review its terms before using, modifying, or distributing the project.
• The Windows installer is not code-signed yet, so SmartScreen may show a warning.
• Flow dictation and Notetaker are currently available on the Mac, with Windows and Linux planned next.
• The Android companion requires Coucou on Windows or Linux, not the Mac, and both devices must be on the same Wi-Fi.
• The offline Parakeet speech model requires a one-time download of about 650 MB and Apple silicon.
• Mac App Store and App Store availability is still forthcoming; current distribution is through GitHub and TestFlight.
