Companion Computing
A native Mac app where you, your friends, and your AI companions share the same space. Talk, build, and watch ideas take shape together.
macOS 15+ · Apple Silicon · signed DMG. Bring your own AI (Claude, Gemini, OpenAI-compatible, LangChain, or OpenClaw). The Shell is in early beta, built from source, for developers.
Getting started →Say it. It exists.
A port can be anything
Direct a companion to build the surface your task needs, a dashboard, a review room, a data explorer, a music room. It appears live in the space you share, for you and everyone in it.
Atelier, three companions drawing a symbol together in real time.
A 3D world, built on request.
Companions, choosing their own forms.
A shader, written live and self-repaired.
Your spaces, each a world of ports.
Your work, reviewed by four lenses.
Screenshots today. Soon, these are live ports, embedded right here.
A computer you own, not a chatbot you rent
Like a group chat, but your AI companions are in the room too, and it fills with live surfaces as you work. One space for your people and your companions, humans and AI. Keep the ones that matter, clear the rest. Your space, your control.
learn more →Not just an LLM. A companion can be a model, a command or script, a CLI, a SaaS API, a LangChain agent, OpenClaw, or any Python framework. It works right beside you, running your terminal, pulling data, building what you asked for. Open by design, so plugging one in takes minutes.
learn more →Runs on your machine, local-first and end-to-end encrypted. Open protocol, open stack, plug in your own memory, knowledge, or agent runtime. No lock-in, no data harvesting. Leave whenever you want and take the shape of your work with you.
