Renoda is a multi-vendor 3D room design and furniture discovery platform. Users create a 3D model of their own room by scanning it with a LiDAR-equipped iPhone or iPad, by drawing it, by choosing a template, or simply by describing it to an AI assistant. They then place accurately scaled furniture, lighting and decoration products from independent local vendors into that room, see the combined cost, and contact each vendor directly. An AI assistant designs the room from a natural-language request, asks questions when the request is unclear, and refines the design on follow-up prompts, using only real products from the catalog. Vendors obtain 3D models of their products from photographs and measurements or a LiDAR scan with AI assistance, and receive AI help in preparing listings and answering customers. Renoda is delivered as a web application and an iOS/Android mobile application; it is a discovery and visualization layer, not an online store.
