A summary, not legal advice.

WHY IT MATTERS

It is easy to miss a permission prompt while your AI agent works in another window. Coucou shows what each session reads, edits and runs, and puts Allow and Deny buttons up top when Claude Code asks.

BUILD FROM THIS

  • Live view of Claude Code, Gemini CLI, Antigravity and other agent sessions, a jump to the right terminal window (macOS), and chat with Claude from the notch. It says there is no telemetry or account and that keys live in the OS keychain.

WHO IT'S FOR

Developers who run several AI coding agents at once.

START IN 5 MINUTES

# Download the macOS build from the Install section of the repository (macOS 15 or later).

CAVEATS

  • The Windows installer is temporarily unavailable because Microsoft Defender wrongly flags the unsigned file. Cursor and Codex pills are coming soon. A young project with about 2,500 stars.
