Best AI for Interior Design

Checked September 29, 2026six toolslisted alphabetically, not ranked

We looked at the six tools people shortlist most when they want to redesign a room from a photo. Below is what each one actually does — free allowance, whether it uses your real photo, whether it keeps the furniture you already own, and how fast it is.

The short answer

The best tool depends on how you start. To redesign a photo of a room you live in, JanvAI and RoomGPT are the simplest — JanvAI can keep the furniture you already own. To buy the furniture you see, MeltFlex. To stage listings at volume, REimagineHome. For floor plans and 3D, Planner 5D or Homestyler.

We built one of the tools below. The comparison is factual, and each short review says where another tool is the better choice.

How We Compared

We built this comparison from each tool’s own website, checked on September 29, 2026. Five questions decide the columns:

1

Free allowance

What you can try without paying.

2

Real-photo redesign

Whether it works from a photo of an existing room.

3

Keeping your furniture

Whether the tool says your existing furniture stays.

4

Shoppable furniture

Whether real, buyable products appear in the design.

5

Speed

Each tool's own published claim.

Where a tool’s site does not answer a question, we write “Not stated” rather than guessing. The six tools are listed alphabetically, not ranked. JanvAI is ours, and it is judged by the same rules — including the you can see in the table.

The Six Tools, One by One

What each one is good at, and where another tool is the better choice.

Homestyler — The Closest to Professional CAD

Best for: 3D modeling, rendering, and construction drawings.

Free tier includes unlimited 1K rendering and a catalog of 100,000+ 3D models, with Pro+ from $6.8/month. It's closest to professional CAD in this group — parametric stairs and roofs, plumbing and electrical, construction drawings, DWG import. The depth is real and so is the learning curve.

JanvAI — Redesign a Photo of Your Own Room

Best for: Starting from a photo of the room you actually live in.

One free successful generation after sign-in, shared across our design tools — not a daily refill. You upload a photo of your own room and get a redesign back; leave furniture removal off and your existing furniture stays as the starting point. We don't link to shoppable products, so if buying the exact sofa in the render matters to you, the next two tools do that better.

MeltFlex — Buy the Furniture You See

Best for: Seeing a piece in your room and purchasing it.

Its first generation is free and needs no card, and it goes further than most on the shopping side: furniture comes from IKEA, Amazon and Wayfair with price comparison across stores, so you can see a piece in your room and buy it. It also covers floor plans to 3D and video walkthroughs. The trade-off is that the free allowance is a single generation, and its own page doesn't say whether it preserves furniture you already own.

Planner 5D — Floor Plans, 3D, and Whole-Home Planning

Best for: Drawing a plan first and furnishing it after.

Free plan with unlimited projects, though only about half the furniture catalog; Premium is $19.99/month. It's the one here built around drawing: floor plans, whole-home 3D, and an AI Studio that bills per model and credit. If you're photographing a room you already live in and want a redesigned image back, this is a heavier path than you need.

REimagineHome — Staging Listings at Volume

Best for: Real estate staging, especially many listings at once.

Five free designs with no card, then $14–$99/month. Its credit system is unusually clear: generating a design costs one credit, and adding real shoppable products costs two — chatting and exploring ideas is free. Listing batch processing and reference photos sit on the Pro tier and up, which makes it the strongest of the six for real estate work at volume.

RoomGPT — The One-Photo Quick Look

Best for: The fastest possible single redesign.

The simplest of the six: one photo in, a redesigned room out. Its homepage doesn't publish plan details or pricing, so check before you commit to it as your main tool.

Who JanvAI Is For

JanvAI is built for one thing done simply: upload a photo of your own room, pick a style, and see a design direction in that actual space before you spend anything. You can keep the furniture you already own by leaving removal off. Pro includes 100 generations a month and Premium 200, at one credit per generation.

We don’t sell the furniture you see, and we don’t do floor plans or construction drawings — if you need those, the tools above are the better fit.

Frequently Asked Questions

Short answers, checked against each tool’s own site.

What is the best AI for interior design?

It depends on how you start. To redesign a photo of a room you live in, JanvAI and RoomGPT are the simplest — JanvAI can keep the furniture you already own. To buy the furniture you see in the design, MeltFlex. To stage real estate listings at volume, REimagineHome. For floor plans and 3D modeling, Planner 5D or Homestyler.

Is there a free AI interior design app?

Yes. As of September 29, 2026, five of the six tools compared here have a free tier: JanvAI gives one free generation after sign-in, REimagineHome gives five free designs without a card, MeltFlex makes the first generation free, and Planner 5D and Homestyler have permanent free plans. RoomGPT's homepage does not publish pricing details.

Which AI interior design tool is best for a single room?

For redesigning one room from a photo, the photo-first tools are the shortest path: JanvAI and RoomGPT each return a redesigned room from a single upload, and JanvAI can keep your existing furniture when furniture removal is left off. Planner 5D and Homestyler are built for whole-home plans, which is more than a single room needs.

Can AI interior design tools keep my existing furniture?

Some can. JanvAI keeps your existing furniture when you leave furniture removal off, and REimagineHome states that room structure can be preserved. Planner 5D's AI Studio redraws scenes at points you set. MeltFlex, Homestyler and RoomGPT do not state on their own sites whether existing furniture is preserved, so we list them as "Not stated" rather than guessing.

Which AI interior design app is best for realtors?

For staging listings at volume, REimagineHome is the strongest of the six: five free designs to start, listing batch processing on the Pro tier and up, and real shoppable products included from Pro. When you publish staged images, label them as virtually staged and keep the original photo available — disclosure rules vary by MLS and location. See virtual staging for realtors.

Do I need design experience to use these tools?

Not for the photo-based tools. JanvAI and RoomGPT take a room photo and a style choice and return a redesign — no floor plan and no CAD skills involved. The learning curve starts with the modeling tools: Planner 5D asks you to draw floor plans, and Homestyler is closest to professional CAD with parametric elements and construction drawings.
