Best AI Room Design Apps in 2026

Planner 5D is the best all round room design app for people who want a measured plan, not just a pretty image. You draw a floor plan, add walls, doors and windows, furnish it from a catalog, and view the result in 2D and 3D. That editable plan is useful for renovation, furniture layout and talking to a contractor, because sizes and positions are real.

The free plan covers unlimited projects but only part of the furniture catalog, with full access and advanced rendering on Premium. AI design generation is also more limited on the free tier. Planner 5D suits DIY planners who want control over layout, and who will use a photo restyler alongside it for style ideas.

Homestyler combines a 3D room planner with AI tools, and its free Basic plan is unusually generous for renders. You can build a room in 2D or 3D, furnish it from a large model library, and produce unlimited renders at 1K resolution. That makes it easy to test several layouts without paying for each render.

AI credits on the free plan are limited, and a high quality AI staging image can cost more credits than the free allowance. Higher resolution renders also need a paid plan. Homestyler suits users who want a free, editable 3D planner with good renders, and who will pay only when they need high resolution or more AI images.

RoomGPT is the fastest way to see a room in a new style. Upload a photo, pick a style, and get a restyled image in seconds. That speed makes it ideal for brainstorming, because you can try ten styles in the time it takes to build one 3D plan. The workflow is simple enough for anyone, with no floor plan or furniture catalog to learn.

The limits are clear. The free allowance is small, often one design, and there is no editable plan to take to a contractor or furniture store. Prices and free terms are shown after login in some cases, so check them before you rely on RoomGPT for a full project. Use RoomGPT for style exploration, and Planner 5D or Homestyler for a plan you can build from.

Interior AI offers a wide range of styles for photo restyling and virtual staging. You can restyle a furnished room, stage an empty room for a listing, or try a style you have not considered, all from a photo. That variety helps real estate agents and homeowners who need a staged look quickly, without hiring a photographer and stager.

There is no ongoing free plan in many reports, so regular use needs a subscription. Renders are images, not editable floor plans, so you cannot measure furniture or change a wall position from the result. Interior AI suits users who need many style options and staging images, and who will pay for volume rather than using a free trial.

IKEA Kreativ is the most practical free tool when you plan to buy IKEA furniture. You can scan a room, remove existing furniture in the view, and place real IKEA pieces to scale, which removes much of the guesswork about size and fit. Because the furniture is real and buyable, the design can turn directly into a shopping list.

The catalog limit is obvious: only IKEA products are included, so a room with mixed brands cannot be previewed fully. A full 3D scan also needs supported hardware, though simpler room views work more widely. IKEA Kreativ suits IKEA shoppers who want a realistic preview, and it pairs well with a general AI restyler for style ideas beyond IKEA.

REimagineHome lets you edit a room photo by describing changes in plain language, which feels more natural than picking from a fixed style list. You can change a wall color, swap a sofa style or stage an empty room, and the tool updates the image. Interior, exterior and staging options cover both homeowners and real estate listings.

The free trial covers only a few designs, and conversational edits with real product links need higher plans. Like other photo tools, results are images rather than measured plans. REimagineHome suits users who want to describe a change and see it, rather than building a room from scratch in 3D.

Spacely AI focuses on fast photo restyles and virtual staging. You upload a room photo, choose a style or staging option, and get a render quickly, with trial credits that in some offers carry no watermark. That makes it useful for real estate agents and homeowners who need a clean listing image without a long setup.

Credit costs vary by render type, and paid prices vary by plan, so check the current pricing page before you commit to a volume project. Spacely AI does not offer an editable floor plan, so it is best for images and staging rather than renovation planning. Use it when a fast, clean restyle is the goal, and a 3D planner when measurements matter.

Houzz is the inspiration and shopping companion to an AI design app. Its photo library covers almost every room type and style, and many photos link to real products you can buy. You can also find local designers, contractors and stores, which helps when an AI render needs a professional to make it real.

Houzz is not primarily an AI photo restyler, and its design tools are lighter than Planner 5D or Homestyler. Use Houzz to gather ideas, save photos you like, and shop real products, then use an AI restyler or 3D planner to apply those ideas to your own room. That pairing gives you both inspiration and a plan you can act on.
