The short answer
A fast, beginner-friendly browser tool that feels almost like a game and gets you a usable floor plan in minutes. Its free tier is genuinely usable (not a trial) with the full library, real-time 3D, and AI styling. The limits: 2 projects and roughly 30-50 objects each on free, cloud-only storage, and AI renders gated behind limited credits.
