Floor Plan AI converts a short written description of a space into a floor plan in seconds. You can generate technical 2D layouts, 2.5D views or 3D isometric models, and download them as PNG images or GLB 3D files.
There are templates you can tweak room by room, or you can write your own prompt. After signing in with Google, the free trial includes one plan, which is enough to see whether it suits your project.
