Voice coding agent for macOS. Hold a hotkey, speak to your codebase, hear answers back.

Hold Option+D and speak. The agent reads your files, edits code, runs commands, and talks back — all streamed to your terminal via the duck CLI.

Interrupt mid-sentence and it stops immediately. Nothing is hidden.

Requires macOS 15.2+ and an OpenAI API key.

brew tap mblode/tap
brew install --cask rubber-duck

Or download the latest DMG directly.

The duck CLI installs automatically on first launch.

duck ~/projects/myapp          # attach a workspace and stream events
duck say "fix the auth bug"    # send a typed message
duck sessions                  # list sessions
duck doctor                    # check system health

• Direct downloads: Check for Updates… in Settings
• Homebrew: brew upgrade --cask rubber-duck

• Menu bar icon hidden? Press Option+Shift+D to open Settings directly
