Before you compare features or pricing, answer one question: does your project start with a photo of an existing home, or with a blank canvas? AI home design tools fall into two distinct workflows, and picking the wrong one wastes your time. Photo-based tools like Remodel AI restyle what already exists. Plan-based tools like Planner 5D and Drafted help you draw something new. Here is how to choose your category first, then your tool.

Choosing Your AI Home Design Tool: Photo-Based vs. Floor Plan-Based

The two categories differ at their starting point. Photo-based remodeling tools take an image of your actual home and apply a new look. Plan-based tools let you draw walls, doors, and rooms from scratch, producing an editable 2D or 3D model you can keep refining.

Remodel AI's own guidance draws this line clearly: for restyling an existing house, its app handles interior redesign, exterior facade redesign, and landscape design. But for new construction, it points users elsewhere entirely — to 2D/3D floor planners like Planner 5D, HomeStyler, or SketchUp Free, which let you build from a blank canvas.

So ask yourself two questions. Do I have a real space I want to visualize changing? Then you need a photo tool. Am I creating a new layout or majorly reworking one? Then you need a floor planner. The output differs too: rendered images versus editable plans and models.

Photo-Based Remodeling Tools: Quick Visualizations

Photo-based tools are built for speed. Reviewer Marija Liatukaitė, who tested Remodel AI among thirteen design apps, describes the workflow simply: you take a photo, choose a theme, and the app applies a new look. Remodels can cover full interiors and exteriors, or narrow down to specific floors, walls, and paint changes.

The trade-off is accuracy. Liatukaitė found results can be inconsistent depending on the photo you upload, and the preset style preview icons don't always match what the AI actually delivers. That makes these tools great for exploring directions, weaker for precise planning.

Remodel AI stands out for scope: its team describes it as a free AI tool covering interior redesign, exterior facade redesign in eleven architectural styles, and landscape design in one app — while most free competitors handle interiors only. Their recommended workflow is to render the exterior first to set the architectural style, then render each interior room in a coordinated style. The free tier includes three designs, with no card required.

From-Scratch Floor Planning Tools: Detailed Design and Editable Models

Plan-based tools serve a different job: new construction or major layout work. Planner 5D offers multi-room 2D and 3D floor plans, with a free tier that carries HD limits. A Planner 5D comparison guide recommends it — alongside RoomSketcher — specifically when you need an editable floor plan and 3D project, and notes it offers a broader platform for developing and editing design projects.

Drafted, built by a San Francisco team, targets homeowners, architects, and builders who want to explore layouts before detailed design. You specify rooms, house shape, and lot requirements, generate alternatives, then refine your preferred concept. Features include editable floor plans, furnished views, exterior renders, and shared projects. Its free plan includes one generation per week.

The key advantage here is iteration. Unlike a rendered photo, an editable plan survives change: move a wall, resize a room, regenerate. That is what makes these tools suitable for the planning stage rather than just visualization.

Decision Framework: Choosing Your AI Home Design Tool

Use this matrix to place your project in the right category before you evaluate any specific product. The two workflows map to different tools based on their core functions, as described in their documentation and reviews.

Read the rows as a sequence: identify your starting point, confirm your goal, then check the output and export you need. If your first row answer is "existing photo," stop comparing floor planners — they are the wrong workflow. If it is "blank canvas," a photo tool cannot give you an editable plan.

Comparative Overview of Leading AI Design Tools

Within each category, the leading options differ in scope and audience. Remodel AI is the photo-based pick, scoring 9.4/10 in its own site's comparison of free tiers, with interior, exterior, and landscape design in one app and three free designs. Planner 5D scores 8.7/10 in the same comparison, offering multi-room 2D and 3D floor plans on a free tier with HD limits. Drafted takes a generation-based approach aimed at early-stage layout exploration, with one free generation weekly and paid tiers scaling up the number of generations.

For exterior work specifically, a Planner 5D guide notes that Planner 5D supports outdoor projects through its landscape design features, while competitors split exterior and interior into separate generators. If you want room, exterior, and floor plan tools under one roof, that breadth matters.

One caution on scores: the 9.4 and 8.7 figures come from Remodel AI's own blog, which has an obvious interest in the ranking. Treat the feature descriptions as reliable and the rankings as promotional context.

Professional Integration: CAD and BIM Export Capabilities

For architects and builders, the decisive question is whether a design can leave the tool and enter professional software. Here the two plan-based tools diverge meaningfully.

Planner 5D promotes a one-click Export to CAD feature producing industry-standard formats compatible with applications like AutoCAD. But Architecture Lab's architect-reviewed verdict is blunt about the limits: outbound compatibility is a Professional-tier 2D drawing in DWG or DXF, plus a PDF printed from the web version — and nothing else leaves in a form another design tool can model with. The reviewer calls a 2D plan handed off that way "a drafting starting point some way short of a finished drawing set," and notes compatibility with other software is only partial.

Drafted goes further. Its developer-facing documentation says exports start with editable geometry for CAD and BIM, delivered as DXF or IFC files, so you can continue reviewing, detailing, and refining in your drafting tools. Its FAQ confirms plan-download and export workflows for PDF, CAD, and BIM — but with a caveat: you must open the download options in your project to see which formats are available for that design and any applicable pricing before you purchase. Availability and cost vary by design.

Remodel AI's documented functionality is photo-based exterior and interior redesign; nothing in its descriptions covers CAD or BIM export of floor plans. If professional handoff is your requirement, that rules the photo category out entirely.

Making Your Choice: Aligning Tools with Project Goals

Select an AI home design tool based on whether your project starts with an existing photo for visualization or a blank canvas for detailed floor planning, and confirm professional export capabilities if needed. Restyling your current home's facade, yard, or rooms? Remodel AI's photo workflow fits. Designing something new? Choose Planner 5D for accessible multi-room 2D/3D planning, or Drafted if you need DXF and IFC export into CAD and BIM tools.

You will know you have chosen correctly when you can name your primary workflow and your tool's export path: photo-based remodeling with rendered images as output, or from-scratch floor planning with editable plans — and, for professional handoff, a confirmed DXF, DWG, or IFC export with its pricing checked before you commit.
