Interior design AI running entirely on your own machine
- Problem
- Laying out furniture takes ergonomics and circulation into account — and the tools that do it require the cloud, a subscription, and technical knowledge from someone who just wants to furnish a bedroom.
- Approach
- The system takes a floor plan (or you draw one from scratch), infers the real dimensions in meters, and generates a layout that respects ergonomics and circulation, in 2D and 3D.
- Technical decision
- Local-first: diffusion rendering runs on the machine itself, on Apple Silicon, with no cloud. Zero inference cost, and the user's floor plan never leaves their computer. FastAPI and SQLite at the core, React with Vite in the editor.
- Outcome
- Building. The guiding principle is layperson-first: auto-fill whatever it can and degrade gracefully when the data isn't there.
