Installation

Mac app

Prerequisites

macOS 13 or later
Git — comes with Apple's Command Line Tools; dum offers to install them if missing
A Claude subscription that includes claude-opus-5-5 and claude-fable-5-1. No API key or paid-usage route. The subscription must grant access to both models.

The app carries its own Node and Claude Code runtime. No terminal is needed.

Optional bundled voice dictation needs macOS 14 or later on Apple Silicon. It uses OpenSuperWhisper's local model and your configured recording shortcut; microphone and Accessibility permissions are required.

Sign in to Claude when prompted. Dum never sees your password.
Choose a Git project folder.
Click the characters or press Cmd+Shift+D to open the conversation.

Dum lives in the menu bar and a small floating pair. There is no Dock icon.
