VRoom - AI-Powered 3D Room Editor

"Welcome to Vroom — where your ideas come to life.

Say what you need — a desk, a new vibe, a splash of color — and Vroom brings it into your space.

Move things around with the touch of a mouse. Jot down thoughts in your notebook. Every piece in the room reflects what’s on your mind.

With a little help from your built-in assistant, your words turn into walls, colors, and cozy corners.

This is your thinking space — where your ideas are made real."

Inspiration

The idea for VRoom came from the frustration of trying to visualize room changes without expensive design software or professional expertise. We were inspired by:

  • Lofi Study Culture: The aesthetic of cozy, productive spaces that help people focus
  • Natural Language Interfaces: Making complex 3D editing as simple as having a conversation
  • Multi-Agent AI Systems: Leveraging specialized AI agents that work together like a real design team
  • Interactive Learning Environments: Creating spaces that adapt and respond to user needs

We wanted to democratize interior design by making professional-quality room visualization accessible through simple natural language commands.

How we built it

Architecture Overview

VRoom uses a sophisticated multi-agent architecture where specialized AI agents collaborate:

User Request → Agent Pipeline → 3D Rendering
     ↓              ↓              ↓
  Chat UI  →  Multi-Agent AI  →  Three.js Scene
