Draw Together

Exploring AI-Driven Real-Time Collaboration

Can AI build a fully functional, multi-user real-time app from scratch? That was the core question behind this experiment.

Inspired by Figma’s collaborative canvas, "Draw Together" tests the limits of AI-assisted development. To guide the AI effectively, I first mapped out the underlying network architecture to understand how it would structure local peer-to-peer communication.

Using Claude Code and Xcode, I brought the app from concept to code in just a few hours. When two or more Macs connect to the same Wi-Fi network, the app instantly detects peers and syncs them live:

• Live Cursor Tracking: Watch collaborators move across the canvas in real time.
• Interactive Drawing: Select pencil tools, customise colour palettes, and sketch together.
• Playful Interaction: Drop a pin on another user's cursor for a quick, fun touch.

Building a network-aware, multi-user application in a single afternoon proves how dramatically AI collapses the gap between creative ideation and functional prototyping.
