They differ most on sign-up, export limits and watermarks. Planloom is free with no account and no watermark; RoomSketcher and Planner 5D are the most complete home-design suites; ArchiVinci and Maket focus on AI layout generation.

How we compared
- Hard filters: works in a browser, has a usable free tier, produces a real floor plan (not an interior mood image).
- Then: does the AI generate the plan itself (text, sketch or photo) or only assist a manual editor; what the free tier exports; sign-up; watermark.
- Where we could not confirm a fact on the vendor's own site, the table says “Not verified”.
Which one fits
- Quick plan, no account, clean export → Planloom.
- A full home-design suite with furniture and photoreal 3D → RoomSketcher or Planner 5D.
- Heavy AI layout exploration on a paid plan → ArchiVinci or Maket.
- Fully manual, open-source, no AI → OpenPlan3D or Sweet Home 3D (desktop).

Are the plans accurate enough to build from?
They are concept plans with real dimensions you set (measure one wall and the plan scales). Have a licensed professional check structure and local code before building.
