Software advice
Best AI Interior Design Software in 2026
AI interior design software is a browser or desktop application where designers and homeowners draw rooms, place furniture and materials, and produce 3D views, with AI that converts a floor plan image into an editable plan, suggests layouts or renders photorealistic pictures. It is not a virtual staging service for listing photos and not full architectural CAD.
Quick answer
RoomSketcher ranks first for a free start, a $12 Pro plan and AI floor plan conversion. Planner 5D fits homeowners who want the cheapest paid tier. pCon.planner fits professionals who need manufacturer catalogs. Chief Architect suits full home design with printed prices.
Someone choosing room-planning software has a floor plan on paper or as a PDF, a furniture idea and a picture they need to show a client or a partner. The vendors now name AI in every pitch: scan-to-plan conversion, layout suggestions, AI renders and credits that meter them. The pages show less about what a render costs, which plan removes the watermark and where your uploaded plans are stored. This ranking weighs printed prices, the AI features each vendor names on its own pages, render limits, data statements and fit for designers versus homeowners. We read vendor pages in November 2026 and ran none of the tools, so speed and quality claims are the vendors' own.

RoomSketcher ranks first because the free plan, the $12 Pro price and the AI Convert step all appear on the pricing page, and a privacy policy exists. A buyer can test a real plan before paying and then add branding and print to scale. It loses ground where credit limits on AI Render and 3D photos are only marked with asterisks, so heavy render users must read the fine print.
Strong on
- AI Convert turns a PDF, image or scan into an editable project, with 1 free conversion
- Pro is $12 per month billed yearly and adds a complete furniture library and own branding
- A privacy policy is published and mentions retention for accounting and tax law
Weak on
- AI Render and 3D photos are asterisked, so credit or plan limits apply on top of the price
- Hosting region and whether uploads train AI models are not stated on the pages opened
Skip it if: Firms that need manufacturer product catalogs or full architectural drawing control beyond floor plans and 3D views. Free has 2 credits and 1 AI conversion. Pro adds 5 monthly credits and branding; asterisked items carry limits.
- 2
Planner 5D ranks second because Premium is the cheapest paid tier here and carries AI floor plan recognition, AI Studio credits and a catalog of 10,000+ items. Free offers unlimited projects. Price clarity is weaker: the page shows EUR 4.99, 59.99 yearly and 19.99 monthly together, and no privacy policy loaded at the paths we tried.
Strong on
- Free plan has unlimited projects and half of the furniture catalog
- Premium names AI floor plan recognition, photorealistic renders and AI Studio credits
- Design Battles on the free plan can win Premium access
Weak on
- The pricing page lists EUR 4.99, 59.99 and 19.99 for Premium, so the true monthly cost needs confirming
- The privacy policy returned a 404 on the paths tried, so data handling is unchecked
Skip it if: Professionals who need supplier catalogs or contractual data terms, since the policy page was not reachable. Premium shows EUR 4.99 a month, with 59.99 yearly and 19.99 monthly billing options also printed, so the figures differ.
- 3
Coohom ranks third because Pro unlocks floor plan upload into 3D, a 100K+ premium catalog and unlimited 4K renders without a watermark, and AI Layout suggests plans sized to the room. The gaps keep it below the top two: Basic caps at 3 projects with watermarked 1K renders, Pro lists 10 renders a month in its limits, and no headquarters or data policy was found.
Strong on
- Pro turns an uploaded floor plan into a 3D project and removes render watermarks
- AI Layout, AI Modeling and AI Render Enhancement are named on the homepage
- Enterprise tier and a free trial are linked from the pricing page
Weak on
- Basic is capped at 3 projects with low-detail models and watermarked 1K renders
- Pro lists 10 renders per month among its limits, despite the unlimited 4K claim
Skip it if: Buyers who need a stated headquarters or hosting region before signing, since neither was on the pages opened. The Pro individual price shows EUR 29 struck against EUR 25 a month; billing is yearly at EUR 300.
- 4
Homestyler ranks fourth because Basic gives unlimited 1K rendering and 100,000+ free models, and the paid tiers start under EUR 5. It is the only tool here with ISO 27001 printed on its homepage. It sits below the leaders as tier names were not extracted cleanly, 4K needs purchase each time on Basic, and the privacy path returned a community profile, not a policy.
Strong on
- Basic includes a cloud 3D floor planner with unlimited 1K rendering
- ISO 27001 is stated on the homepage as the information security certification
- Homestyler AI converts a 2D plan or sketch into an editable 3D house model
Weak on
- 4K renders must be purchased each time on Basic, and free renders use Homestyler coins
- Two euro tiers and the per-seat plan had no extracted names, so plan comparison needs the live page
Skip it if: Buyers who need a readable privacy policy or data terms, since only a community profile loaded at that path. Individual Pro starts from EUR 4.52 with 100 AI credits monthly; a higher tier starts at EUR 9.13.
- 5
Space Designer 3D ranks fifth because it prints two plain prices, $25 and $45, and its AI Rendering turns a 2D plan into an HD or 8K image in the browser. The cost is credits: renders, AI images and plan detection share one monthly pool, and CAD exports need Ultimate. There is no free plan beyond a card-required 5-day trial.
Strong on
- AI Rendering produces HD or 8K images from a 2D floor plan without a download
- Premium includes 2,500+ furniture items, PDF export, roofs, stairs and annotations
- Ultimate lifts projects to unlimited and floors to 10
Weak on
- Renders, AI images and plan detection draw on one pool of 200 or 370 credits a month
- Premium caps at 25 projects and 5 floors, and CAD export requires Ultimate
Skip it if: Homeowners with one room to plan, since the trial needs a card and no permanent free plan is offered. Premium is $25 monthly with 200 credits; Ultimate $45 with 370. The 5-day trial needs a card.
- 6
pCon.planner ranks sixth because it solves a different problem from the homeowner tools: planning with actual supplier articles in one session, plus AI image rendering from a project in one click. Free community registration and a 30-day trial lower the barrier. It sits lower since the page shows no prices and homeowners are not the audience.
Strong on
- Articles and product lists from every connected supplier catalog can sit in one project
- AI image rendering creates a visualization from a project in one click
- Community registration is free for architects, interior designers and facility managers
Weak on
- Only one page was opened, with no plan prices and no privacy statement
- Catalog content depends on what each manufacturer supplies
Skip it if: Homeowners and hobbyists, because registration is reserved for interior professionals. No plan prices on the planner page; community registration is free for interior professionals, plus a 30-day trial.
- 7
SketchUp ranks seventh because it is a general 3D modeler, not an interior planner with AI at its center. The pricing page prints Go at $10.75 and Pro at $33.25, and the homepage names photorealistic materials and AI renders. Buyers who want furniture libraries and automatic plan conversion get less out of the box than with the planners above.
Strong on
- Pro includes the desktop 3D modeler and the complete professional toolkit
- Go has unlimited cloud storage and a mobile viewer
- Free self-paced training is offered through SketchUp Campus
Weak on
- Go is iPad and web only, and photoreal materials on Go are iPad only
- The homepage names AI renders but gives no credit limits or detail
Skip it if: Beginners who want a drag-and-drop room planner with automatic plan conversion out of the box. Go runs on iPad and web only. Pro is $33.25 per user monthly, billed annually, and adds the desktop modeler.
- 8
Houzz Pro ranks eighth because it manages the business around a design job more than the design itself. The homepage names AI estimates under Project Financials, AI note-taking and an AI-backed mobile app. No price could be read, since the pricing page returned 503, and the privacy page opened was the consumer Houzz policy. That makes it a fit for design firms rather than for picking a room layout.
Strong on
- AI estimates, AI note-taking and Houzz AI expert support are named on the homepage
- A mobile app with project tracking and integrations is listed
- Training webinars and a help center are offered
Weak on
- Pricing was not published on the pages opened and the pricing page gave a 503
- The privacy page found is the consumer Houzz policy, not one for Houzz Pro
Skip it if: A homeowner planning a single room, since the product targets builders, designers and remodelers running client work. Not published on the pages opened; the pricing page returned a 503 and the site offers a demo or sign-up.
- 9
Floorplanner ranks ninth because it draws plans well and is free for schools, but no AI feature appeared on the homepage, pricing or privacy pages opened. For an AI-focused list that is the deciding gap. Its API docs are linked and credits are sold for rendered images, but the Plus and Pro figures could not be tied to plan names, so cost is unconfirmed.
Strong on
- Basic gives free 2D and 3D floor plans with doors, windows and walls
- API documentation is linked from the site, for teams that want to connect the planner
- The site states the tool is free for schools worldwide, an uncommon education offer for this kind of software
Weak on
- No AI feature was named on the pages opened
- Basic has a 10 minute cooldown and no included credits for rendered images
Skip it if: Buyers who want AI conversion or AI renders, since none was named and Plus and Pro prices are unconfirmed. Basic is free with a 10 minute cooldown; Plus and Pro prices were not mapped to plan names.
- 10
Chief Architect ranks tenth because the homepage prints real prices ($1,995 per year, $229 monthly) and a trial download, but names no AI feature. It is professional home design software, priced far above the consumer planners. The plan labels are as printed and their naming was not confirmed, and only the homepage was opened. Training webinars are separate.
Strong on
- Annual, annual-rate monthly and monthly prices are all printed
- A trial version download is offered on the homepage, so the software can be tested
- Live webinars, seminars and personal or custom training are listed
Weak on
- No AI feature was named on the homepage opened
- Monthly billing costs $229 against $166.25 at the annual rate, and training is sold separately
Skip it if: Homeowners or occasional designers, since the license starts near two thousand dollars a year and shows no AI features. Homepage prints $1,995 per year, $166.25 per month at the annual rate, or $229 billed monthly; plan names unconfirmed.
- 11
Palette CAD ranks last because the one page opened shows no price, no AI feature and no privacy policy; the privacy URL tried returned 404. It describes 3D planning software for digital interior design, including bathroom and tile planning, and it names a Dutch partner network in a May 2026 news item. It is a demo-first product.
Strong on
- Described as 3D planning software for individual interior design concepts
- Bathroom and tile planning is named among the use cases
- A free live demo is available on request
Weak on
- No prices and no AI feature were named on the homepage
- The privacy policy URL tried returned a 404
Skip it if: Buyers who want to test a self-serve free plan or see AI features before talking to sales. No prices on the homepage; a free live demo is requested through the site.
How these AI interior design software were judged
Which AI interior design software turns a plan into a usable room most reliably?
The vendor pages name AI in different places, so output depends on the job. RoomSketcher, Planner 5D, Coohom, Homestyler and Space Designer 3D each name a scan or image-to-plan step, and Coohom adds AI Layout suggestions sized to the room. pCon.planner names AI rendering from a project and ties it to supplier catalogs, which matters when the furniture must exist in a real product line. Floorplanner, Chief Architect and Palette CAD named no AI feature on the pages opened, so their value is drawing control. Reviewers describe AI conversion as a starting draft that still needs wall and dimension checks, and the vendors give no accuracy figures.
How much does AI interior design software cost for one project or a small studio?
Entry prices run from free to about two thousand dollars a year. RoomSketcher Pro is $12 per month billed at $144 per year, Planner 5D Premium is EUR 4.99 per month on its headline price, and Space Designer 3D Premium is $25 per month. SketchUp Go is $10.75 per month per user billed annually, Pro $33.25. Chief Architect prints $1,995 per year or $229 monthly. Renders are the hidden cost: Coohom Pro lists 10 renders per month in its limits, Homestyler Individual Pro gives 100 AI credits, and Space Designer 3D shares 200 credits across renders and AI images. Houzz Pro prices were not published on the pages opened.
Where do my floor plans and client projects go when I upload them?
Uploaded plans and projects are stored in each vendor's cloud, but few pages say more. Homestyler states ISO 27001 on its homepage. RoomSketcher's privacy policy says some data is kept for accounting and tax law, and Floorplanner's GDPR policy describes personal data handling without a fixed period. None of the pages opened for these tools stated whether uploads train AI models, and hosting regions were not stated except that pCon.planner's maker has an address in Ilmenau, Germany. Planner 5D's privacy page returned a 404 in our check, and Chief Architect and Palette CAD privacy URLs did the same. Ask each vendor in writing before uploading client plans.
How hard is it to leave an interior design platform after a year of projects?
Lock-in comes from catalogs, credits and project formats. Projects built from a vendor's furniture library or supplier catalogs do not open elsewhere, and pCon.planner projects lean on manufacturer data. Credits are monthly allowances: RoomSketcher Pro gives 5 a month, and Coohom Basic is capped at 3 projects. Chief Architect bills monthly at a higher rate than annual. SketchUp's desktop modeler is a stronger exit route because its Pro plan is a modeling tool, not a catalog service. Export formats were not checked on the pages opened, so test one project export before committing.
Should a homeowner, a freelance designer or a design firm pick which tool?
Homeowners fit RoomSketcher, Planner 5D, Homestyler or Floorplanner, because each has a free plan and needs no CAD training. Freelance designers who render for clients look at Coohom, Space Designer 3D or RoomSketcher Pro for branding and watermark-free output. Firms that specify manufacturer furniture fit pCon.planner, whose community registration is reserved for interior professionals. Designers running a business with estimates and client tracking fit Houzz Pro, which names AI estimates and note-taking but showed no price. Architects and remodelers who draw whole houses fit Chief Architect or SketchUp Pro. Palette CAD targets digital bathroom and tile planning and starts with a live demo.
How to choose an AI interior design software in three steps
- Start from the plan you already have. Take one real floor plan, a PDF or a photo of a sketch, and test the conversion on the free tier of two tools. RoomSketcher gives 1 free AI conversion, Planner 5D lists AI floor plan recognition under Premium, and Homestyler converts a 2D plan to a 3D model on its homepage. Check wall positions and room sizes against the original. If you draw every plan fresh, an AI converter matters less than the editor and measurements, and Floorplanner or Chief Architect may fit better than a render-heavy tool.
- Count the renders you need before comparing prices. Estimate how many finished images a typical project needs, then match that to each plan. Coohom Basic gives watermarked 1K renders, Pro unlocks 4K without watermark, Homestyler Individual Pro includes 75 renders each for 2K and 4K, and Space Designer 3D shares credits between renders and AI images. A cheap monthly price with a small credit pool can cost more than a higher flat plan once a client asks for revisions. Write down the number of rooms, views per room and revision rounds first.
- Ask about data and catalogs before you upload client work. Send each shortlisted vendor three questions: where plans are stored, whether uploads train AI models, and how to export a project. Most pages opened for this ranking did not answer them, and Houzz Pro's privacy page was the consumer policy. Then check the catalog: if you specify real products, test whether the brands you quote are in pCon.planner's supplier catalogs or the vendor's library, since a generic sofa will not satisfy a client who wants a named model. Ask too whether a project can be exported, because the pages opened did not describe export formats.
Frequently asked questions
What is the best AI interior design software in 2026?
RoomSketcher ranks first in this list for most buyers: a free plan, a $12 per month Pro plan billed yearly, AI Convert for turning a PDF, image or scan into an editable plan, and a published privacy policy. Planner 5D and Coohom follow for cheaper or more render-focused use. Professionals who specify real products should look at pCon.planner.
Is there free AI interior design software?
Yes, several have free tiers. RoomSketcher Free includes 2 credits and 1 AI floor plan conversion. Planner 5D Free has unlimited projects with half the furniture catalog. Coohom Basic allows 3 projects with watermarked renders, Homestyler Basic includes unlimited 1K rendering, and Floorplanner Basic has a 10 minute cooldown. SketchUp and Chief Architect showed no free plan, only paid licenses or a trial.
Can AI software convert my floor plan image into an editable plan?
RoomSketcher, Planner 5D, Coohom, Homestyler and Space Designer 3D each name a conversion or plan detection feature on their own pages. RoomSketcher says its AI Convert makes an editable project in under five seconds, which is the vendor's claim. Check wall lengths against your original, since none of the pages opened publish an accuracy figure.
What does AI interior design software cost per month?
As of November 2026, printed entry prices include $12 per month for RoomSketcher Pro billed yearly, EUR 4.99 for Planner 5D Premium, from EUR 4.52 for Homestyler Individual Pro, and $25 for Space Designer 3D Premium. SketchUp Go is $10.75 per user billed annually. Chief Architect lists $1,995 per year, and Houzz Pro and Palette CAD publish no price.
Which tool works for professional interior designers rather than homeowners?
pCon.planner is aimed at interior professionals such as architects, interior designers and facility managers, with free community registration, a 30-day trial and supplier catalogs in one session. Houzz Pro covers the business side with AI estimates and note-taking. SketchUp Pro and Chief Architect fit designers who model whole buildings, though Chief Architect named no AI feature.
Do these tools keep my floor plans private or train AI on them?
The pages opened did not say whether uploads train AI models for any of these tools. RoomSketcher's privacy policy mentions retention for accounting and tax law, and Homestyler states ISO 27001 on its homepage. Planner 5D, Chief Architect and Palette CAD privacy URLs returned errors in our check, so get written answers before uploading client plans.
How is interior design software different from AI virtual staging?
Interior design software builds a plan or model you control: walls, furniture, materials and views. Virtual staging tools take a photo of an existing room and add furniture to it for listings. This ranking covers the first kind. For listing photos, see the virtual staging category, and for technical drawings see the AI CAD software category.
Does Houzz Pro publish its prices?
Not on the pages opened for this ranking. Houzz Pro's pricing page returned a 503 error when fetched in November 2026, and the homepage points to Get a Demo or Sign Up. The vendor names AI estimates, AI note-taking and an AI-backed mobile app. Ask for a quote and check the Houzz Pro privacy terms, since the privacy page opened was the consumer policy.
