Best AI Interior Design App in 2026

Planner 5D is our pick for most homeowners who want a plan they can actually build from. You draw a measured floor plan, place furniture from a large catalogue, and view the room in 2D and 3D. That editable model matters when you need to check whether a sofa fits a wall, not just whether it looks good in a photo. AI tools can recognise a plan, generate images, and create panoramas, which helps at the concept stage.

The catch is the paywall for the full experience. The free plan gives unlimited projects but only half the catalogue, and Premium costs $19.99 per month or $59.99 per year, with a Professional tier for higher-resolution renders. If you only want one quick restyle, a photo tool is faster. If you are planning a renovation, Planner 5D is the tool to learn.

Homestyler is the best free planner for many users. The Basic plan offers unlimited 1K renders and a large library of free models, so you can build a room, try layouts, and render views without paying. Pro+ starts at $6.80 per month and adds higher-quality output and more features. For renters and homeowners testing layouts before buying furniture, that free tier is genuinely useful.

The limit is AI staging. Free AI credits are few, and a staging image can cost more credits than a basic render, so photo restyling is not Homestyler's strength. Use Homestyler to plan the layout and test furniture placement, then use a photo restyler for style inspiration. Together, those two steps cover most home projects.

RoomGPT is the fastest way to see a room in a new style. Upload one photo, pick a room type and a style, and receive a redesigned image with a before-and-after view. That speed suits homeowners who want ten ideas in an evening, or agents who want a quick concept for a listing photo. Credit packs start at $9 for 30 credits in many listings, which makes occasional use cheap.

The weakness is what RoomGPT does not do. You cannot edit the room plan, move walls, or get measurements from the output, and the site does not publish its free allowance or prices before login, so check inside the app before buying credits. Use RoomGPT for inspiration, then measure and plan the winning idea in Planner 5D or Homestyler.

Interior AI suits users who need many restyles quickly, especially for virtual staging. Upload a photo of an empty or furnished room, choose a style, and receive a photorealistic version that can help buyers picture the space furnished. That volume use case, for listings or rental adverts, is where Interior AI earns its place over single-use tools.

The caution is pricing. Published prices have varied across 2026 listings, from monthly subscriptions to yearly tiers, so the only reliable figure is the one on the pricing page today. Start with the free trial or limited free renders, test the styles you actually need, and only then choose a plan. For one room, a cheaper credit pack elsewhere may be enough.

REimagineHome stands out for its conversational flow. Instead of picking from a fixed style list alone, you can describe changes in plain language and refine the result, which feels closer to briefing a designer than pressing a filter button. Five free designs let you test that flow without a card, and Pro plans add shoppable product links and batch processing for listings.

The trade-off is tiering. The features that make REimagineHome distinct, including chat edits, reference photos, and real product links, sit on paid plans, and monthly prices range from $19 to higher tiers depending on credits. If you want fast staging with products you can buy, REimagineHome is a strong pick. If you want a floor plan, pair it with a planner.

HomeDesigns AI is the broadest photo tool here. It covers living rooms, bedrooms, kitchens, bathrooms, and home offices, plus exteriors and gardens, with a large style library that helps when you are unsure what you like. Starting at $22 per month for 100 credits in many listings, it suits homeowners exploring several rooms or several styles at once.

The catch is credit maths. Different tools cost different credit amounts, so a plan that looks generous can run out faster on high-resolution or exterior renders. Test the free credits first, count how many designs your project actually needs, and choose the tier that covers that count. For style exploration across a whole home, HomeDesigns AI is a good value pick.

Collov AI is built for virtual staging, and that focus shows. Upload a listing photo, choose a style, and receive a furnished version that helps buyers see potential in an empty room. Unlimited regeneration on paid plans means you can retry a room until the furniture placement looks natural, without worrying about each retry costing extra credits.

The free trial is small and watermarked, so treat it as a quality test, not a staging solution. For agents and landlords, the $19 per month starting price in many listings is reasonable if you stage several listings a month. For a single home project, a credit pack tool may be cheaper.

Spacely AI suits users who start from a sketch or a model, not just a photo. Architects, designers, and keen renovators can turn a sketch into a photorealistic render, or restyle a photo with more control than a one-click tool offers. Trial credits let you test that workflow before paying, and credit packs suit occasional professional use.

The downside is complexity and price movement. Subscription and pack prices have shifted during 2026, so check the pricing page for the current offer, and expect a learning curve if you use sketch or model inputs. For pure photo restyling, a simpler tool may be faster. For design professionals who need sketch-to-render, Spacely AI is worth testing.

IKEA Kreativ solves a different problem from the rest of this list, and for many buyers it is the most useful tool here. Instead of imagining a room, you scan your room and place real IKEA furniture in it, at real sizes, so you can see whether a bookcase fits and how it looks with your walls. There is no design subscription, and the tool lives inside the IKEA app and website.

The limit is obvious: you can only preview IKEA products. If you plan to buy elsewhere, Kreativ will not help, and a full 3D scan needs a supported phone. Use Kreativ when you are ready to buy from IKEA, and use a planner or restyler for the wider design question. For IKEA shoppers, it is free, practical, and hard to beat.
