At Google I/O 2026, Demis Hassabis highlighted DeepMind's focus on World Models as a critical step toward AGI. With real-time video editing via natural language already here, it got me thinking about the immediate applications for entirely new, dynamic user interfaces — and the fitting room was the first thing that came to mind.

What if we could replace crowded, busy fitting rooms in retail stores with intelligent screens?

LiveLook is a real-time virtual try-on app that completely changes the browsing experience. It uses real-time video diffusion to render garments onto you — live, as you move.

How It Works

• Real-time garment rendering — Uses the Lucy VTON model (by Decart) to render clothing onto a live webcam feed in real time via WebRTC.
• Gesture-based browsing — Swipe your hand to browse the product catalog and give a thumbs up or OK sign to add items to your cart, all powered by Google MediaPipe.
• Voice control — Search for products by speaking, using the Web Speech API.
• Zero UI friction — No buttons needed. Browse, try on, and shop entirely through natural gestures.
