Best Free AI Floor Plan Generators in 2026

AI floor plan generators serve two genuinely different needs, and most searches conflate them. The first is layout planning: drawing an accurate, to-scale 2D top-down map of a home with walls, doors, and dimensions, then placing furniture.

The second is style visualization: taking a photo of an existing room and seeing it rendered in a different style or color palette without changing the actual layout. Picking the right free tool depends entirely on which one you actually need.

I reviewed the top free AI floor plan tools of 2026 based on accuracy, free-tier limits, watermarks, and whether each tool is built for precise layout work or fast style previews.

1. Coohom, Best Free Option for Full Layout-to-3D Workflow

Best for: Homeowners who want to go from blank space to a complete, navigable home design.

Coohom's free floor planner can start from a blank space or an uploaded floor plan, generate a full home layout, place furniture, and let you preview the result in both 2D and 3D, all in browser with no download required. The free tier offers unlimited layouts and unlimited 2D/3D editing, with a limited monthly allowance of photorealistic renders, enough for a single renovation project.

Best for: Homeowners and designers who need both an accurate layout and a 3D walkthrough.

Pricing: Free, unlimited layouts and editing; limited monthly photorealistic renders, no credit card required.

2. Planner 5D, Best Free Option for Smart Furniture and Fixture Placement

Best for: Users who want AI to suggest optimal layouts based on real room dimensions.

Planner 5D uses an AI-powered Smart Wizard that analyzes your room dimensions to automatically suggest optimal fixture and furniture placements, going beyond a simple blank-canvas drawing tool. In independent testing on a real living room layout, it scored among the strongest free options specifically for drawing accurate, to-scale 2D floor plans.

Best for: Dimension-aware layout suggestions with accurate 2D drawing.

Pricing: Free tier available; paid plans expand rendering and features.

3. RoomSketcher, Best Free Option for Accurate 2D Drawing

Best for: Users who need a precise, to-scale floor plan rather than a stylized concept.

RoomSketcher scored close behind Planner 5D in testing for accurate 2D floor plan drawing, making it a strong alternative specifically for users who care more about dimensional precision than 3D rendering polish.

Best for: Precise, measurement-accurate 2D floor plans.

Pricing: Free tier available; paid plans expand export options.

4. Remodel AI, Best Free Option for Fast Style Visualization

Best for: Users who want to see their existing room in a new style without redesigning the layout.

Remodel AI renders your actual room in more than 30 styles in about 10 seconds, free for three designs with no credit card required. It is built specifically for style visualization rather than layout planning, scoring highest among tested tools for that exact use case, seeing how a room would look with a different aesthetic while keeping the same physical layout.

Best for: Quick style previews of an existing room, not new layout creation.

Pricing: Free, 3 designs, no credit card required.

5. Homestyler, Best Free Option for Multiple Input Methods

Best for: Users who want to start from dimensions, a sketch, or just a text description.

Homestyler supports three different starting points, dimensions, sketches, or text prompts, and can produce a functional first-draft layout in under five minutes regardless of which method you use. This flexibility makes it a strong choice if you don't have a clean starting input and want the tool to adapt to whatever you have on hand.

Best for: Flexible floor plan generation from whatever input you already have.

Pricing: Free tier available.

6. Magicplan, Best Free Option for Scanning a Real Room With AR

Best for: Users who want to capture an existing room's actual dimensions using their phone.

Magicplan is the best mobile-only AR-based scanner among the tools tested, letting you walk through a real space with your phone to generate an accurate floor plan rather than drawing one from memory or a rough sketch.

Best for: Capturing accurate dimensions of an existing space via phone scanning.

Pricing: Free tier available; paid plans unlock additional export formats.

7. VisualGPT, Best Free Option for Sketch-to-Layout Conversion

Best for: Users who have a rough hand-drawn sketch they want turned into a polished plan.

VisualGPT lets you upload a rough sketch or describe your room requirements to generate a fully realized 2D or 3D layout instantly, with high-definition rendering that shows realistic textures for flooring, walls, and furniture. It works well as a starting point for testing multiple structural concepts before committing to a physical renovation.

Best for: Turning a rough sketch into a polished, renderable layout.

Pricing: Free tier available.

8. ZSky AI, Best Free Option for Unlimited Text-to-Layout Generation

Best for: Users who want quick concept layouts purely from a text description.

ZSky AI generates floor plan concepts from a text prompt in roughly two seconds per layout, with unlimited free generation and no daily limit. It works well for residential, apartment, office, and commercial concepts when you just need a visual starting point to bring to an architect rather than a precise, measurement-accurate plan.

Best for: Fast, unlimited concept layouts from a text description alone.

Pricing: Free, unlimited generation.

9. Edraw.ai, Best Free Option for Professional-Looking Diagrams

Best for: Users who want a polished, presentation-ready floor plan output.

Edraw.ai produces professional-looking floor plans suitable for sharing with clients or contractors, rounding out the toolkit for users who need a clean final diagram rather than just a rough concept.

Best for: Clean, presentation-ready floor plan diagrams.

Pricing: Free tier available.

Head-to-Head Comparison

Which Tool Should You Choose?

You want a full layout plus a 3D walkthrough: Coohom covers the most complete workflow on its free tier.

You need precise, to-scale dimensions: Planner 5D and RoomSketcher both led independent testing for 2D accuracy.

You just want to see your current room in a new style: Remodel AI is purpose-built for that and scored highest specifically for style visualization.

You have a real room you want scanned accurately: Magicplan's AR scanning beats manual measuring and dragging.

You only have a rough idea, not a sketch or measurements: ZSky AI or Homestyler can generate a usable starting concept from text alone.

Final Thoughts

The single biggest mistake people make searching for an "AI floor plan generator" is not distinguishing between layout planning and style visualization, since the strongest tool for one is rarely the strongest tool for the other.

If you're starting a renovation from scratch, Coohom or Planner 5D give you the most complete, accurate workflow. If you already love your room's layout and just want to see it in a different style, Remodel AI gets you there in seconds.

Treat any AI-generated layout as a fast first draft to react to, not a finished blueprint, since none of these tools understand your specific furniture, habits, or structural constraints the way a human designer eventually needs to.
