DASH is a desktop canvas where Claude Code, Codex, Cursor, Gemini and Grok run side by side with terminals, browsers, a live git diff and a task board. Agents can message each other, hand off work and spin up teammates while you watch it all on one screen. Drive it by typing or by voice. It runs the CLIs you already pay for, so there is no markup on your AI usage. Built on Windows first, runs on macOS too. One payment, no subscription, and a 3 day free trial with no card.
