About

Ground Control Chat

Features
Read full description

Every Claude Code session on your Mac becomes a pixel pilot on your phone. Ground Control shows your AI coding agents as unique little creatures marching on a neon city street. Cyan means working. Lavender means idle. Pink means one of them needs you. Tap a pilot to open its conversation. Read every reply as it streams in. Send new orders from the couch, the train, or the other side of the world, and watch your actual terminal on the Mac update live. SETUP IN ONE MINUTE Run one command on your Mac (npx @clastres/groundcontrol), scan the QR code it prints, done. No account. No signup. PRIVATE BY ARCHITECTURE Your pairing key is generated on your Mac and shared only through the QR code you scan. Everything travels end to end encrypted. Our relay routes sealed bytes and cannot read them. We store nothing. UNIQUE PILOTS Every session hatches its own creature, generated from its identity, with its own walk cycle. It keeps that face forever. Requires a Mac running Claude Code and the Ground Control daemon.
