SquareCubed turns a flat Square e-commerce store into a virtual 3D showroom you can walk through. It uses Vertex AI to understand a store's products and WebGi to render them in real time, so a merchant's existing catalog becomes an explorable space with no extra 3D modeling work.
It won the Square + Google AI Hackathon 2023, taking "Best reinvention of in-person & online experiences." Built with Svelte and Next.js on the WebGi SDK, with Cloudflare Workers tying it together.
