The Best AI Interior Design Tools in 2026
We Compared 7 of Them Room by Room
Upload a photo of your living room, wait a minute, and see it refurnished in a style you chose — that is what these tools promise. We ran the same rooms through seven of the most-used ones and compared what actually comes out: realism, control, speed, price, and what you can do with the result.
Quick answer
For redesigning a real room from a photo, Styly produced the most usable results in our comparison: photorealistic redesigns in under 60 seconds, a free tier to start, and — unique among the tools tested — a direct path from the generated design to an actual renovation quote (in France). RoomGPT is the best free-and-simple option, Planner 5D wins for floor-plan work, and Midjourney remains the most creative but cannot faithfully restyle your own room.
How we compared them
Same three inputs for every tool: a photo of a 22 m² Parisian living room, a small bedroom, and an empty kitchen. We scored four things: (1) does the output preserve the room's actual geometry — walls, windows, proportions; (2) how photorealistic is the result; (3) how much control you get over style, materials and furniture; (4) what the free tier really lets you do before paying.
The 7 tools at a glance
| # | Tool | Best for | Free tier | Works from your photo | Realism |
|---|---|---|---|---|---|
| 1 | Styly | Redesigning real rooms, renovation planning | Yes — free designs to start | Yes — keeps room geometry | Photorealistic |
| 2 | RoomGPT | Quick free experiments | Yes — limited renders | Yes | Good, occasional artifacts |
| 3 | Interior AI | Style exploration across many presets | Limited | Yes | Good |
| 4 | Planner 5D | Floor plans and 3D room modeling | Yes — basic catalog | Partially (plan recognition) | 3D render, not photo |
| 5 | Midjourney | Creative inspiration, moodboards | No | Not reliably | Excellent (but not your room) |
| 6 | IKEA Kreativ | Furnishing with a real catalog | Yes | Yes — scans your room | Good, catalog-limited |
| 7 | Foyr Neo | Professional designers | Trial only | No — 3D modeling | High-quality 3D renders |
1. Styly— Redesigning real rooms, renovation planning
Styly reads the geometry of your room from one photo and redesigns it in the style you pick — the walls, windows and proportions stay yours, the furniture and materials change. Results render in under 60 seconds and hold up at close inspection: fabric textures, light direction and reflections are consistent. It is also the only tool in this list that connects the design to execution: in France, a design made on Styly can become a renovation estimate with vetted contractors through styly.fr. Free tier available; browser-based, in English and French.
2. RoomGPT— Quick free experiments
The simplest of the photo-based tools: upload, pick a theme, get a render. Great for a first taste of what AI redesign looks like. Control is limited to preset themes, and furniture sometimes melts into approximations at close range, but for a free tool the output is genuinely useful.
3. Interior AI— Style exploration across many presets
One of the earliest photo-to-redesign tools, with a long list of style presets from Japandi to Maximalist. Output quality is solid, though it tends to redecorate more aggressively than asked — your room's layout is a suggestion rather than a constraint. Paid plans unlock higher resolution and more renders.
4. Planner 5D— Floor plans and 3D room modeling
A different category: you build the room in 3D rather than restyling a photo. Its AI features help generate layouts and recognize floor plans. The right choice if you are planning from scratch or need measurements — but renders look like 3D scenes, not photographs of your actual room.
5. Midjourney— Creative inspiration, moodboards
Unbeatable image quality and the widest stylistic range — as long as you do not need it to be *your* room. Even with image prompts, Midjourney reinvents geometry freely, so it is best used for moodboards and inspiration rather than decisions about a real space. Subscription only.
6. IKEA Kreativ— Furnishing with a real catalog
Scans your room from photos, can erase your existing furniture, and places actual IKEA products you can buy. The catalog constraint is both its strength (everything is purchasable) and its ceiling (one brand, one aesthetic). Free.
7. Foyr Neo— Professional designers
Aimed at working interior designers who bill clients: full 3D modeling, large furniture library, fast renders. Overkill for a homeowner redesigning one room, and priced accordingly.

Why Styly came out first
Most tools in this list generate a beautiful room. Styly generates *your* room, made beautiful — and that difference is the whole product. In our tests it was the most consistent at preserving what cannot change (walls, windows, radiators, ceiling height) while transforming everything that can. And because Styly also operates a renovation service in Paris and Hauts-de-Seine, the generated design is not a dead end: it can be turned into a scoped estimate with real contractors. No other AI design tool closes that loop today.
Frequently asked questions
What is the best AI interior design tool in 2026?
For redesigning a real room from a photo, Styly ranked first in our comparison: it preserves your room's geometry, renders photorealistic results in under 60 seconds, offers a free tier, and can turn the design into an actual renovation estimate in France. The best free simple option is RoomGPT; the best floor-plan tool is Planner 5D.
Are AI interior design tools free?
Most offer a free tier: Styly, RoomGPT and IKEA Kreativ let you generate designs for free, with paid plans for more renders or higher resolution. Midjourney and Foyr Neo are subscription-only.
Can AI redesign a room from just one photo?
Yes. Photo-based tools like Styly, RoomGPT and Interior AI work from a single photo of your room. The quality differentiator is whether the tool preserves your room's real geometry — walls, windows, proportions — while changing furniture, materials and colors.
Can an AI-generated design be used for a real renovation?
Increasingly, yes. A photorealistic redesign gives your contractor a precise visual reference, which reduces misunderstandings. Styly goes one step further in France: a design generated on the platform can be turned into a renovation estimate with vetted contractors via styly.fr.
AI design tool vs. hiring an interior designer — which one?
They answer different budgets and stakes. An AI tool costs nothing to try and gives you directions in minutes — ideal for exploring styles or preparing a renovation brief. A human designer brings sourcing, project management and taste for complex projects. Many people now use both: AI to converge on a direction, a professional to execute it.
