About

Floor Plan Overlay lets you compare property floor plans at a matched real-world scale.

This is a vibe-coded project — built quickly and iteratively with an AI assistant. Expect rough edges; there are no guarantees of accuracy.

Your data stays on your device. The floor plans you add, and anything you save to your library, are stored only in this browser (IndexedDB) — nothing is ever uploaded to a server.
