How to read this rating
- These tools are very different, so we score within each category: software built for interior designers does not compete with a general assistant.
- Fit counts double: a tool built for your sector scores 5; a general assistant that does the job well with good prompts scores 3.
- General assistants (Copilot, ChatGPT, Claude, Gemini) share the same fit score because they do the same kind of job; ease, price, availability and privacy set them apart, and we score privacy for professional use with client data. Ties are broken on privacy.
- Best if you use shows whether a tool works best inside Microsoft 365 or Google Workspace. Copilot and Gemini are not marked down for it, but they are only the best choice if you already work there.
- Scores are based on official information checked on October 25, 2026. This is not a lab test: it is our rating against fixed criteria, and we keep the reason behind every score.

How we score: 1 to 5 on each criterion against a fixed scale (fit ×2, total out of 30), from official documentation, plans and prices checked on the date shown. We compare within each category. This is not a lab test.
My first pick to start is Gemini: it has a free plan and covers both redecorating from a photo and drafting the proposal. Among the specific tools, HomeByMe and Planner 5D are the most complete for plans and 3D.

What you can upload to an AI tool
AI apps for interior design accept four kinds of input, and each one produces a different result.
- Real photo. Redecoration in another style while keeping the room structure.
- Text. A visual proposal or moodboard from scratch based on a description.
- 2D plan. A layout and explorable 3D scene from the floor plan.
- Sketch. A clean render based on a hand drawing.
Floor plans and 3D: design
To create floor plans, measure a room and design in 3D, these apps and software start from the floor plan and real scale, not only aesthetics.
Planner 5D
It turns a floor plan into a 3D scene with furniture and finishes. Its Premium plan adds AI floor plan recognition (upload a plan and turn it into a 3D project) and monthly AI studio credits. Example task: upload the plan of an 860 sq ft home and test three living room layouts before the first meeting. Limit: the free catalog covers only part of the furniture, and unlimited renders are on the Professional plan.
HomeByMe
It lets you draw a home plan, furnish it in 3D and generate realistic views, with a free plan limited in projects and images. Example task: draw a scaled kitchen plan and compare two furniture sets for the client to choose. Limit: free images carry restrictions and paid prices are on its site.
Floorplanner
A 2D and 3D floor plan editor in the browser, made to draw and measure without installing anything. The free plan allows up to 5 projects with watermarked exports; upgrading to HD or 4K uses credits. Example task: draw the floor plan of a shop and export a 2D view to discuss with the client. Limit: I could not confirm its subscription prices or interface language.
Magicplan
An app that measures a room with your phone and produces its floor plan; on iOS Pro it can use the LiDAR scanner. It includes 2 free projects and pricing depends on new projects per month. Example task: measure a living room during a visit and bring the plan to the studio to start designing. Limit: accuracy depends on the device, so check with a tape measure before moving to CAD.
Polycam
It scans spaces with LiDAR or photos and turns them into a 3D model. The free plan includes limited captures and Basic costs $30 a month or $150 a year. 2D and 3D floor plans are a Business feature. Example task: scan a home to renovate and export the model to measure on it. Limit: Basic does not include floor plans; those are on Business ($33 a month per user, billed yearly).
Redecorate: start from a photo
If the room already exists, you upload a photo, choose a style and the tool redecorates without touching walls or windows.
Interior AI
It redecorates a room from a photo: you pick the room type and style and get variations that keep the structure. It is the most direct way to show a client three directions in one afternoon. Limit: I could not confirm the free plan or price on the official site, and third-party sources disagree, so check its site before you buy.
RoomGPT
Another photo-based redecoration app, using credits to generate redesigns. Example task: upload a bedroom photo and ask for a Japandi style to compare with the studio proposal. Limit: free plan terms and prices vary by source and I could not confirm them on its site, so check there.
Realistic views: image and video
For moodboards, concepts and presentations, combine a tool that generates with another that enhances or animates the result.
Midjourney
It generates high-quality images from text, ideal for moodboards and ambience concepts before there is a physical space. Example task: create four Mediterranean restaurant looks to choose palette and materials. Limit: no free plan, and it does not measure or respect a real plan.
Adobe Firefly
It generates and edits images with free daily credits and works with Photoshop. Example task: change the wall cladding in an existing render to test another texture. Limit: the Standard plan costs $9.99 a month and paid credits run out under heavy use.
Magnific
It upscales images and adds detail, useful to sharpen a render before presenting it. It is one of the tools covered in the Founderz program for interior designers. Limit: its pricing page lists no free plan.
Runway
It turns an image or a render into a short video. Example task: animate a living room render into a five-second walkthrough for the presentation. Limit: it is a visual extra, not a replacement for modeling, and the free plan gives 125 one-time credits.
Assistants: proposals and briefs
For text work, budgets and concepts, a general assistant covers what the visual apps do not.
ChatGPT
It helps define palettes, write style descriptions, structure a brief and generate concept images. Example task: paste notes from a client meeting and get an organized brief. Limit: it does not validate measurements or buildability. It has a free plan with limits and paid plans from $8 a month.
Gemini
It accepts a photo of the room and redecorates it keeping structure and light, and also drafts the proposal. Example task: upload a living room photo and ask for three styles to compare. Limit: check that it respects windows and doors. It has a free plan.
Microsoft Copilot
Useful where you already work in Office: a materials spec in Word, a budget in Excel and a deck in PowerPoint. Example task: turn a furniture list into a budget table. Limit: it adds little on the visual side.
Claude
Strong at reading a long brief, summarizing requirements and drafting the client proposal. Example task: analyze a tender document for a shop and list what constrains the layout. Limit: it is not a visual redecoration tool.
Free tool
Interior design prompt generator
Pick your case, adjust the options and get a complete prompt ready to paste into ChatGPT, Copilot, Claude or Gemini.
Open the generatorFree software to make house plans
If you want to make house plans with free software, not every app works the same for an architect, an interior designer or a homeowner. Before you draw the first floor plan, compare these points in each tool.
- 2D and 3D. A good program draws the plan in 2D and shows it in 3D, with views from several angles and realistic 3D rendering.
- Scale and precision. To measure and design with precision you need a scaled plan, with surface and area for each room.
- Furniture and finishes. Check whether you can add furniture, windows, doors, stairs and textures, and whether the catalog is unlimited or limited on the free plan.
- Export and import. Check whether it exports to PDF, DXF or OBJ, the file formats CAD and BIM use, and whether it lets you import your plan.
- Intuitive interface. An easy-to-use platform, with a web version or mobile app, saves you the learning curve of professional software.
- Views and virtual tours. Some tools generate 360° images so the client can walk through the space in a virtual tour; Matterport is an example of capturing real spaces for this.
- Subscription and watermarks. The free plan usually limits projects and adds watermarks; check the subscription cost before delivering a project.
The best software to plan with depends on the setting: in real estate it shows a building or a home before a renovation, and in landscaping it helps plan a garden or a pool. Many apps generate the plan automatically from a photo or a scan, and some need hardware with LiDAR. Check what each basic plan includes, how many project versions you can save, how much you will spend per month and how to manage and move furniture without redrawing the plan; professional quality is usually on the paid plan, with a cost worth comparing on its website.
Other mobile apps that plan guides cite, such as Floor Plan Creator or DrawPlan, are left out of this comparison because I could not confirm their free plan or price. And in real estate, portals such as Zillow can include floor plans in their listings, a use where these programs save time. For the garden or pool of a project, computer-aided design (CAD) software is still the reference.
In practice, I would start with a plan in HomeByMe, Planner 5D or Floorplanner, and leave technical modeling and architecture design to CAD and BIM software.
How to choose the right tool
Choose by project phase and by whether you need real measurements or just inspiration. Use this checklist as a filter:
- Data privacy and GDPR: do not upload client photos or plans without knowing what is stored and whether it trains the model.
- Scale and measurements: if you need a scaled plan, pick floor plan software, not an app that only redecorates.
- Integrations: check that it exports to formats your CAD or presentation accepts.
- Cost per user: start on the free plan and pay only if your project volume justifies it.
- Language: confirm whether the interface and support are in Spanish.
- Learning curve: photo apps take minutes; floor plan software takes a bit more practice.
Tip
Test two tools on the same real space using the free plan. Compare how many adjustments you need, not the first image.
Important
AI visualizes; it does not measure or validate construction. Check measurements, materials and codes before presenting a proposal, and check usage rights for generated images, an area with legal doubts.
From floor plan to 3D proposal
This four-step workflow combines plan and image tools. With good AI prompts for interior design you get a presentable result instead of a generic one.
- Measure and draw the plan. Use Magicplan or Polycam to measure and Planner 5D, HomeByMe or Floorplanner to draw the 2D floor plan.
- Furnish in 3D. Try two or three layouts and save the views.
- Redecorate and explore styles. Upload a photo to Interior AI, RoomGPT or Gemini and generate variations; use Midjourney for moodboards.
- Write and present. Ask ChatGPT, Gemini or Claude for the brief and the spec, and export the result for the client.
AI speeds up the phase before technical modeling in CAD or BIM, but does not replace it: judgment on materials, measurements and coherence stays with the designer.
Training for your team
Picking the tool is the easy part; getting the whole team to use it well, with data protected, is harder. Founderz teaches a method that works with Copilot, ChatGPT, Claude, Gemini and the specialist tools for interior designers.
Prompts to get started
Three prompts for the most common tasks. Replace what is in brackets with your case. For more examples, see the AI prompts for interior design.
Redecorate from a photo
Use the attached photo of my [living room] as the base. Keep the position of the windows, doors, ceiling and floor the same.
Change only the decor to a [Japandi] style: a beige linen sofa, an oak coffee table and a floor lamp.
Keep the natural light and framing. If you are going to change anything else, tell me before generating the image.Organize the client brief
I am pasting my notes from a client meeting: [text].
Turn them into a brief with: space and measurements, users, needs, style, materials and approximate budget.
Mark anything missing as "to confirm" and write the exact question I should ask the client.Create a moodboard
Act as an interior designer. Prepare a text moodboard for a [family dining and living room] with [a warm, sober atmosphere]: a 5-tone palette, 6 materials with upkeep, 5 furniture pieces and 3 layers of light.
Mark with "validate" anything that depends on measurements or budget. Do not invent brands or prices.Limits of AI in architecture and interior design
AI can generate a beautiful image that does not hold up in reality, and that is where the interior designer’s judgment still rules.
- Technical accuracy and real measurements. AI visualizes, it does not measure: a render can show a piece of furniture that does not fit.
- Material coherence. It can combine textures that do not work together on site; the designer validates.
- CAD and BIM integration. Visualizations are not executable plans, and the step to technical modeling is manual.
- Image rights. Who owns the rights to images created with AI is still a legally unsettled question.
Frequently asked questions
Short answers to what people ask most about AI tools for interior design and how to use them on real projects.
What is the best AI for interior design?
There is no single best one: it depends on the phase. To redecorate from a photo, Interior AI, RoomGPT or Gemini; for plans and 3D, Planner 5D or HomeByMe; for concepts, Midjourney.
What is the best free AI to decorate interiors?
To start for free, Gemini and ChatGPT have free plans with limits, and Planner 5D, HomeByMe and Floorplanner have free versions for plans. Check the limits on each site.
How can I make house plans for free?
Planner 5D, HomeByMe, Floorplanner and Magicplan offer free versions with limits on projects, exports or images. Draw the floor plan, measure each room and pick the one that exports what you need.
What software makes 2D and 3D plans?
Planner 5D, HomeByMe and Floorplanner draw the 2D floor plan and show it in 3D in the browser. For executable technical plans you still need CAD or BIM, and the data box on those plans is called a title block.
How much does AI for interior design cost?
Many have a free plan with limits. Confirmed prices: Planner 5D Premium $19.99 a month, Midjourney from $10 and Adobe Firefly from $9.99. For the rest, check their site.
What program do architects use to design digital plans?
Architects use CAD and BIM software for executable plans. For a first floor plan or a proposal, apps like HomeByMe, Planner 5D or Floorplanner are faster and easier to use.
How do I use AI to design a room?
Upload a photo or a plan, choose style and level of change, generate several variations and adjust the prompt. Then validate measurements and materials before presenting.
What is the best AI to create architectural plans?
No AI replaces CAD for executable architectural plans. To create floor plans quickly, Planner 5D with AI floor plan recognition is one option; the designer validates measurements and scale.
