11 best AI interior design tools in 2026

An AI interior design tool takes a photo of a room and gives it back redesigned: new furniture, new walls, a new style, with the windows and doors where they were. In 2026 there are dozens of them, and on the surface they all do the same trick. The differences show up after the first picture. Can you buy what is in it? Can you change one thing without the AI redrawing the room? Does it work from a floor plan? What does the hundredth render cost?

The best AI interior design tools at a glance

1. MeltFlex AI: the best AI interior design tool overall

Most AI room designers draw furniture that looks plausible and does not exist. MeltFlex starts from the other end. In its own words, "every piece of furniture in the design is a real product from IKEA, Amazon, Wayfair and more", and each one in the picture carries a price and a link. The catalogue spans nine retailers: IKEA, Amazon, Walmart, Costco, Wayfair, Rooms To Go, Pottery Barn, West Elm and Ashley Furniture, with prices compared across stores. A redesign stops being a mood board and becomes a shopping list.

We ran it on an empty living room from MeltFlex's own demo, with a written brief: a low oatmeal linen sofa, a round light oak coffee table, a wool rug, a paper floor lamp and two large plants, and keep the windows, balcony door, oak shelving wall and kitchen island as they are. Every item in the brief came back, and the windows, the door, the island and the empty oak shelves stayed exactly where they were. The one liberty was a third plant where we asked for two.

The same photo through the one click Virtual Staging preset, with no brief at all, came back furnished and styled, but it also added kitchen cabinets and bar stools that were not in the room. The lesson holds for every tool on this list: write what you want and name what to keep.

What MeltFlex does that the rest of this list splits up

• 15 design tools in one account: interior, virtual staging, kitchen, bathroom, exterior, garden, walls, floors, stairs, doors, windows, office, closet, cafe and restaurant, each with its own style presets.
• Any starting point: a room photo, empty or furnished, a floor plan, sketch, CAD plan or scanned plan, a rough 3D view, or a text description.
• Floor plan to 3D: upload a plan and walk the result as an interactive 3D model.
• Photo to 3D furniture: one photo of a chair or sofa becomes a textured GLB or USDZ model in about three minutes.
• Upscaling to 4K and video walkthroughs of a design.
• Apps for web, iOS, Android and Windows, plus an API, a CLI and an MCP server, so Claude or another AI assistant can run designs for you.
• Privacy: "Your photos stay in your account and are never used to train AI."

MeltFlex AI pricing

• Free: your first design is free and needs no credit card. Free renders carry a small MeltFlex watermark.
• Standard: €19 a month, or €12 a month billed €144 yearly, with 490 credits a month. A photo render costs 10 credits.
• Pro: €59 a month, shown at €24 a month billed €288 yearly during the October promotion, with 2,250 credits a month. Commercial use for listings and client work is included on Pro.
• Enterprise: from €200 a month for 8,000 credits, with your own furniture catalogue, PDF quotes and API access.
• A 7 day money back guarantee on paid plans.

Best for: homeowners who want to buy the room they see, interior designers who present to clients, furniture retailers who want their own catalogue in the designs, and anyone who wants photo, plan and 3D in one place. Where it stops: credits do not roll over, and the free tier gives you a taste rather than a working allowance.

2. ReimagineHome: real products, generous free trial

The closest to MeltFlex in spirit. You redesign by chat, attach reference photos, and switch on real products that check out on Amazon or Shopify. It also covers staging, emptying a room, landscaping and sky replacement. Its free trial is the most generous of the big names: "All new users get 5 free designs - same AI, same quality as paid plans."

Paid plans run from Essential at $19 a month for 30 credits to Agency at $119 for 900. A design costs 1 credit, or 2 with real products. The catch is the bottom tier: Essential has "No Next-Gen AI or High Resolution Quality", no reference photos and no real products, so the feature that makes it interesting starts at Pro, $36. Its page title still advertises a range of $14 to $99 a month, which the plans on the same page no longer match.

3. Interior AI: volume, sketches and SketchUp

One of the first and best known, built by Pieter Levels. Upload a room photo, a hand sketch or a SketchUp screenshot and it renders it in one of 50+ styles across 30+ room types, with a Freestyle mode that needs no photo at all. The plans are sized for volume: Pro is $49 a month or $29 billed $349 yearly for 1,000 designs.

Read the plan cards closely. Pro says "Low quality renders" and does not include virtual staging; medium quality and staging start at Premium, $99 a month. There is no free plan, and the FAQ is blunt about refunds: "Unfortunately, we cannot offer refunds as costs incurred for generating AI images are extremely high."

4. HomeDesigns AI: the widest menu

Interior, exterior and garden from a phone shot, hand sketch, blueprint or listing photo, plus video walkthroughs, 2D to 3D floor plans, furniture shopping and a budget estimator. Its Structure-Lock keeps walls and windows in place. Standard is $22 a month for 100 credits, Pro $29 for 1,000, Expert $37 for 2,000, and "A photo redesign is 1 credit". The yearly discount applies to the first year only, then it renews at the standard price. Free use is 3 credits every 24 hours.

5. Spacely AI: for working designers

Spacely is aimed at professionals. It renders "a sketch, 3D model, or room photo into a photorealistic render in under 60 seconds", connects to SketchUp, Revit, AutoCAD and Rhino, and adds a shared Team Canvas. Personal is $25 a month, or $20 billed $240 yearly, for 500 credits. Note the queue: Personal runs on a "Standard queue · result in 5 minutes", and the 4K and realistic render features are tagged Pro. The free tier is 40 trial credits.

6. ReRoom: unlimited renders at a flat price

If you already design in 3D and just need the render, ReRoom is the simplest deal on this list: "Upload a screenshot of your model. Get a photorealistic render. Your design and materials stay the same." The monthly plan is $39 with unlimited renders, the annual $390 for the first year. The free trial gives 3 renders a day, watermarked and for non commercial use. It does not invent a design for you, which is the point.

7. Collov AI: virtual staging for listings

Collov is built for realtors: staging an empty or furnished listing photo "in under 15 seconds", plus declutter, twilight shots and virtual tours. Plans are priced per photo, from Standard at $19 a month billed $228 yearly for 60 photos to Enterprise at $127 for 526, with extra photos at $0.24. Free trials are watermarked. If you are an agent posting listings, our guide to social media for real estate agents covers what to do with the photos afterwards.

8. Planner 5D: floor plans first

Planner 5D is a home planner first and an AI renderer second. Its AI reads a floor plan from png, jpg, pdf, dwg or dxf and turns it into an editable 3D plan, and its AI Studio takes prompts, photos, sketches and plans through models including Nano Banana 2 and GPT Image. The free plan has no time limit but half the furniture catalogue, and floor plan upload is Premium, from $4.99 a month billed $59.99 yearly. "AI plan recognition and AI Studio use separate allowances." If what you need to draw is a part rather than a room, the tools that turn a photo or sketch into a DWG or DXF are compared in the best AI CAD generators.

9. Homestyler: 3D software with AI added

Homestyler is full 3D home design software with a large model library, and its AI tools (stager, planner, render, animator and the Spark agent) sit in a separate AI Boost membership from $4.9 a month. Credits are spent per action: 10 for a staged image, 25 for a 2K render, 35 for 4K. The free Basic plan includes 3 AI credits and unlimited 1K rendering, but "4K Render needs to be purchased each time". Worth it if you want to build the room yourself, slow if you just want a new look for a photo.

10. Paintit.ai: chat first

Paintit redesigns interiors, exteriors and commercial spaces through a chat box, with Pinterest boards as input. The free plan gives 30 credits at 1K, Starter is $14.99 a month on a 50% promotion, Pro $29.99. "The minimum image cost starts from 3 credits", and watermark free, commercial exports start at Pro, not Starter.

11. RoomGPT: one free try

RoomGPT made AI room redesign famous, and many lists still call it free and open source. The live site gives one free generation after you sign in with Google, then sells credit packs: "There is no subscription model; all purchases are made on a per-credit basis." Unused credits never expire, which is fair for occasional use. It is a single photo in, a single redesign out, with no plans, products or 3D.

How to choose an AI interior design tool

• You want to buy what you see: MeltFlex AI, or ReimagineHome from its Pro plan.
• You have a floor plan, not a photo: MeltFlex AI for plan to 3D, or Planner 5D if you want to draw the plan yourself.
• You render your own 3D models for clients: ReRoom for a flat price, Spacely if you work in a team.
• You stage listings: Collov AI, or MeltFlex's Virtual Staging tool if you also want the furniture to be real.
• You want one look at one room for free: RoomGPT or ReimagineHome's 5 free designs.

Whatever you pick, the brief matters more than the tool. Name the style, the pieces, the materials and what must stay. The same habits that make Nano Banana prompts for Instagram posts and Gemini prompts for product photography work apply to rooms: be specific, give colours a role, and say what not to change.

Posting AI room designs on social media

Most of these renders end up on Instagram, a listing or a client presentation. Two things to know before you post. Instagram may label an AI generated image, which we explain in why Instagram says AI info on a post. And a 16:9 render loses its edges in a portrait feed, so check the Instagram post size and crop before you upload. If you want the posts written and scheduled for you as well, that is what an AI social media tool does.
