What the desktop app does that a terminal can't

Same agent, same rules: it proposes before it acts. A native window buys it long-running work, parallel branches, and a diff you can actually read.

Your workspace, everywhere

The desktop app runs the Matilda CLI. It also stands on its own: one install, no window, same context and same approvals as the app.

Everything the CLI does
