Most AI room tools can make a pretty picture. Far fewer will keep your room, obey a reference, hold a palette and tell you what anything costs. We compared twelve on exactly that.
October 2026, from the team behind MeltFlex AI. We make one of the twelve tools below and put it first, so our own entry carries the longest list of weaknesses on the page.
MeltFlex AI is an AI interior design tool that redesigns a photo of a room you already have, keeping walls, windows and camera angle while changing style, colour, materials and furniture, and then matches that furniture to real products. We built it, and in the list below it sits first among twelve tools we compared on 6 October 2026, from free apps to professional 3D planners. Each entry says what the tool is best for, where it falls short and what it costs, read from the vendor’s own site. Where another tool beats ours on a specific job, that entry says so.
The short answer
For redesigning a room you already own, the top AI interior design tool for redesigning your own room is MeltFlex AI, because it keeps your room’s structure, lets you change one wall, floor or object at a time, and links the furniture to nine real retailers. Planner 5D is the best value 3D planner, Coohom the best for professional renders, and IKEA Kreativ the best free option.
Our order, as of the first week of October 2026:
- MeltFlex AI: best for redesigning and shopping your own room
- Planner 5D: best value 3D planner with AI built in
- Coohom: best for professional-grade 3D renders
- IKEA Kreativ: best free tool, if IKEA is your shop
- REimagine Home: best for redesigning by conversation
- Paintit.ai: best low-cost generative redesign
- Interior AI: best for exploring many styles quickly
- Spacely AI: best for designers rendering their own CAD models
- HomeDesigns AI: best for the widest toolbox in one plan
- Homestyler: best free 3D planner with unlimited basic renders
- HomeByMe: best branded furniture catalogue in a 3D plan
- RoomGPT: best for a fast free first look
How did we compare these AI interior design tools?
We compared twelve tools on five questions that matter to anyone who thinks in palettes and materials: does it keep your room, can you change one element at a time, will it follow a reference, does anything link to real products, and what does it cost. Prices and features were read on each vendor’s own pages on 6 October 2026, with JavaScript running, since several pricing tables only appear that way.
To be exact about method: we use MeltFlex every day, and the weaknesses in its entry come from our own renders. For the other eleven, we read their pricing, plan tables and FAQs and quote them verbatim; we did not run an identical paid test in every tool. Three products were left out. MyArchitectAI accepts “CAD exports (except for floor plans), line drawings, and hand sketches”, not photos of your room. Collov has pivoted to real estate staging. DecorMatters publishes no prices.
Prices for HomeByMe and Homestyler appeared only in euros when we checked, so we quote them in euros rather than guess a dollar figure.
The five questions:
- Is it still your room? Windows, doors, ceiling and floor direction should survive. If they shift, the redesign is fiction about somebody else’s flat.
- Can you change one thing? Testing a palette means changing one wall and nothing else. Tools that regenerate the whole room every time make that impossible.
- Will it follow a reference? Designers think in reference images, not style names.
- Does anything exist? A render you cannot buy from is a moodboard, not a plan.
- What does it really cost? Monthly versus annual, credits versus renders, and what the cheapest plan actually leaves out.

1. MeltFlex AI: best for redesigning and shopping your own room
Best for: homeowners and designers who want to test styles, palettes and materials on a real room, then buy what they chose.
MeltFlex redesigns a photo in one of roughly 25 styles or from your own brief, and keeps the structure of the room in most generations. What makes it useful for palette work is that you can change one element at a time: repaint a single wall, swap the floor, change one sofa, apply a style from a reference photo, without redesigning everything else. It then identifies the furniture in the result and matches it to real listings from nine US stores, among them IKEA, Wayfair, West Elm, Pottery Barn and Costco.
Where it falls short, in more detail than any other entry:
- It follows the mood of a prompt, not the letter. A gallery brief asking for “olive velvet seating, fluted timber walls, a stone fireplace” came back with the velvet and the timber, and a glass bio-ethanol burner instead of stone. Nothing warns you.
- The free tier hides the best feature. Free users see furniture from one retailer, IKEA. The nine-retailer matching, the main reason to choose us, needs a paid plan.
- Colour on screen is not colour on the wall. Like every tool here, it lights rooms with an imaginary sun. Mid-tone greens and terracottas glow on screen and read darker in a real north-facing room.
- It invents expensive objects. Shelving, joinery and art appear because they make pictures look finished. They are also the costliest things to build.
- Scale is a guess. The image has no tape measure. Matched products have real dimensions; the picture does not prove they fit.
- One label is generous. The top quality setting says “4K”; the file it produces is 2K.
- Credits, not renders. Standard’s 490 monthly credits buy roughly a hundred images, and client work is licensed on Pro only.
Price: first design free, no card. Standard $20.99 a month, or $12.99 a month billed yearly. Pro $64.99, or $25.99 a month billed yearly, for 2,250 credits and commercial use.
A MeltFlex render from our public gallery: sage plaster with vertical timber fluting, an olive velvet sofa and a large figurative painting. The green appears in at least three values, deep in the sofa, mid on the wall, pale where the light hits. That spread is exactly what a single paint chip cannot show you, and exactly what a screen exaggerates.
2. Planner 5D: best value 3D planner with AI built in
Best for: people who want to draw the room to scale, move walls and stay on budget.
Planner 5D is a 3D planner first: you build the room, place furniture and see it in 3D, with a Budget Widget. In 2026 it added AI Studio, with what its FAQ calls a “Canvas Agent”, and credits for AI images.
Where it falls short: the free plan gives “Access to 50% of the furniture catalog”, and Premium gets only “Standard Renders”. Unlimited 4K, CAD export and 3D model import sit on Professional.
Price: Premium $19.99 a month or $59.99 a year; Professional $49.99 a month or $399.99 a year ($33.33 a month).
3. Coohom: best for professional-grade 3D renders
Best for: designers who want photoreal 3D renders and walkthroughs from a modelled space.
Coohom offers a library of over a million branded 3D models, unlimited 4K renders and 8K 360-degree walkthroughs on Pro, plus construction drawings on Elite.
Where it falls short: it is a modelling tool, not a photo redesigner, so there is a learning curve. The free plan allows “Up to 3 design projects” with “1K image renderings (with watermark)”, and the Pro plan describes itself as “Concept design only, no implementation”.
Price: Pro $15 a month, or $12 a month billed yearly ($150). Elite $69 per seat, or $58 billed yearly ($699).
4. IKEA Kreativ: best free tool, if IKEA is your shop
Best for: furnishing a room entirely from IKEA without paying for software.
You can “Choose a room”, “Build a room” or “Scan your room”, then place IKEA products that are all buyable. In IKEA’s words: IKEA pitches it as a way to see its pieces “together in your space before you buy”.
Where it falls short: one shop only, and it is a furnishing tool rather than a style or palette tool.
Price: free.
5. REimagine Home: best for redesigning by conversation
Best for: people who would rather describe a change than pick it from menus.
REimagine Home redesigns photos through a conversational flow and offers real shoppable products, with “5 free designs – same AI, same quality as paid plans”.
Where it falls short: the cheapest tier is unusually stripped. In the vendor’s own words it has “Basic staging + light edits using legacy tools”, “No Real Shoppable Products” and “No Next-Gen AI or High Resolution Quality”. The features worth paying for start at Pro. Billing is monthly only.
Price: Essential $19 (30 credits), Pro $36 (200), Advanced $59 (400), Agency $119 (900), per month.
6. Paintit.ai: best low-cost generative redesign
Best for: trying generative redesign cheaply, with furniture suggestions included.
Paintit.ai redesigns photos with a chat interface and “suggests purchasable matches from trusted retailers”, even on the free plan.
Where it falls short: watermark-free output and a commercial licence start only at Pro. “Unused credits do not roll over to the next month”, and “The minimum image cost starts from 3 credits”. The prices we saw were displayed as a 50 percent promotion, so check what you will pay at renewal.
Price: Starter $14.99, Pro $29.99, Max $79.99 a month, shown as half of $29.99, $59.99 and $159.99.
7. Interior AI: best for exploring many styles quickly
Best for: rapid style exploration, including a “Luxury” preset and walkable 3D.
Interior AI generates large numbers of redesigns, and in 2026 added “Walk inside your interior designs in 3D” as a World Labs launch partner. It also claims to suggest “actual furniture you could buy at IKEA”.
Where it falls short: its own plan table labels Pro “Low quality renders” and Premium “Medium quality renders”. There are no refunds: “Unfortunately, we cannot offer refunds as costs incurred for generating AI images are extremely high.” HEIC photos from iPhones are not supported, and the page quotes two different annual prices for Pro ($349 in the table, $390 elsewhere).
Price: Pro $49 a month or $29 billed yearly; Premium $99 or $49; Ultra $199 or $99.
8. Spacely AI: best for designers rendering their own CAD models
Best for: designers who work in SketchUp, Revit, AutoCAD or Rhino and want fast AI renders.
Spacely renders from photos or models, integrates with the main CAD tools, and offers team seats on Studio and Agency.
Where it falls short: no real-product layer, and credits are less predictable than they look: “Credit use may vary based on render options and number of results.”
Price: Personal $25 a month or $20 billed yearly (500 credits); Studio $50 or $40 (1,500 credits, 2 seats); Agency $100 or $80 (3,500 credits, 5 seats). 40 free trial credits.
9. HomeDesigns AI: best for the widest toolbox in one plan
Best for: people who want staging, video, 3D and shopping features in one subscription.
HomeDesigns AI bundles many tools and a “Find & shop the real furniture” feature.
Where it falls short: its pages contradict themselves. The FAQ says Expert “adds team seats and advanced tools like video, virtual staging and 3D”, while all three plan cards list those features. Prices also changed between sessions in different regions, so confirm at checkout.
Price: Standard $22, Pro $29, Expert $37 a month in our US session (100 to 2,000 credits).
10. Homestyler: best free 3D planner with unlimited basic renders
Best for: planning in 3D for free and paying only when you need high resolution.
Homestyler’s free tier includes unlimited 1K renders, plus a small AI Decor allowance.
Where it falls short: on the free plan, “4K Render needs to be purchased each time”, and AI Decor offers “3 credits in total”. Dollar prices did not display for us.
Price: Pro+ from €6.27 a month; Master+ from €10.89; Team €18.37 per seat.
11. HomeByMe: best branded furniture catalogue in a 3D plan
Best for: planning a room in 3D with real branded products from a catalogue of more than 90,000 items.
HomeByMe, from Dassault Systèmes, combines a proper 3D plan with branded furniture and 4K images and video on Pro.
Where it falls short: the free Starter plan offers “2 x Projects” and “5 x Full HD Images”. It is a planner, not a photo redesigner, and prices displayed only in euros for us.
Price: Essentials €29 a month or €25 billed yearly; Pro €59 or €49.
12. RoomGPT: best for a fast free first look
Best for: a quick, free impression of a different style on your room.
RoomGPT is one of the best-known photo redesigners and claims “over 4 million” users.
Where it falls short: it publishes no prices. Its /pricing page returns a 404 and credits are only priced after you log in, while the site banner advertised ‘Use code “FLASH60” at checkout for 60% off all plans!’. No real-product layer.
The quiet-luxury brief from our gallery that asked for a stone fireplace. The flame is a slim glass burner on a timber console under the television, and the wall is smooth white panelling. A beautiful room, and not quite the one that was asked for, which is why every AI render needs reading against its brief.
How do you test a colour palette with an AI interior design tool?
Test a palette by changing one surface per generation and keeping everything else fixed. Start with the largest surface, usually the walls, then the floor, then textiles and the accent. Compare results side by side at the same size, and choose a colour family, not a final paint.
A sequence that works in any tool that allows targeted edits:
- Keep the room, layout and floor identical.
- Change only the walls: “limewash plaster in terracotta on all walls, matte finish, everything else unchanged”.
- Save, then change only the textiles.
- Check the proportions: roughly 60 percent dominant tone, 30 secondary, 10 accent. If the accent dominates, the palette is wrong, whatever the individual colours.
The phrase “everything else unchanged” matters. Without it, most generative tools redesign the whole room on each run, and you end up comparing two rooms instead of two colours.
Is the colour in an AI render the colour you will get?
No. An AI render shows an impression of a colour under invented light on a backlit screen. Use it to choose a family, such as warm green or earthy red, then pick the exact paint using the manufacturer’s light reflectance value (LRV) and large painted samples on two walls, checked morning and evening.
LRV runs from 0 for black to 100 for white, and no image model knows it. A sage that looks airy in a render may have an LRV in the 40s and read much darker in a north-facing room.
Terracotta limewash, a cream modular sofa and a striped rug, from a MeltFlex gallery render. Limewash is a mottled finish that changes with every brush stroke and every hour of daylight. The render shows one pleasing version of it; your wall will show you several.
Which AI interior design tool should you choose?
Choose by the decision you are trying to make. To redesign and furnish a room you live in, use a photo-based tool with real products. To change walls or plan a layout to scale, use a 3D planner. To present concepts to clients, choose by render quality and licensing.
- Redesign your own room and buy it: MeltFlex AI; IKEA Kreativ if you only shop IKEA.
- Plan to scale, move walls, keep a budget: Planner 5D, HomeByMe or Homestyler.
- Professional renders and walkthroughs: Coohom, or Spacely AI if you start from CAD.
- Describe rather than pick: REimagine Home at Pro or above.
- Just curious, no budget: RoomGPT or a free tier of any of the above.
Frequently asked questions
Which AI interior design tool is best in 2026?
For redesigning a room you already live in, MeltFlex AI, because it keeps your room’s structure, allows one-element-at-a-time changes and links furniture to nine retailers. For planning to scale, Planner 5D offers the best value; for professional renders, Coohom.
Is there a free AI interior design tool?
Yes. IKEA Kreativ is free, Homestyler has a free tier with unlimited 1K renders, Planner 5D’s free plan covers half its catalogue, and MeltFlex AI, REimagine Home, Paintit.ai and Spacely AI all offer free first designs or credits.
Can AI keep my room’s layout when redesigning?
Good photo-based tools keep walls, windows and doors in most generations, but not all. Compare the result with your photo and check fixed elements such as radiators, window frames and ceiling lights. If they moved, the design is not reliable advice for your room.
Can AI interior design tools show real furniture I can buy?
Some can. MeltFlex AI matches furniture to nine retailers, IKEA Kreativ uses IKEA’s own range, REimagine Home offers real products from its Pro plan, and Paintit.ai suggests purchasable matches. Most others produce furniture that does not exist.
Are AI interior design tools accurate on colour?
Not exactly. Renders use invented lighting and are viewed on bright screens, so colours shift. Use AI to choose a colour direction, then confirm the exact paint with LRV data and painted samples in your own light.
