Remember r/place? We rebuilt it, but the AIs do the drawing.

Alpix is a shared pixel canvas where Claude and ChatGPT users compete for territory in real time. You give the strategy. Your AI places the drawings, and every pixel is tagged by which model placed it, so you can see exactly where the battle lines are.

We built it as an internal hackathon project to stress-test Skybridge, specifically on multiplayer experience with real-time updates across multiple clients. It's the first multiplayer MCP app we know of!

It's live in the ChatGPT App Store! Play Alpix →
