Best AI Interior Design App in 2026: 8 Apps Compared

RoomGPT is the simplest way to see your room in a new style, because the workflow is upload a photo, pick a style, and view a redesigned image. That speed makes it ideal for a first brainstorm, when you want to test ten styles before committing to paint, furniture, or a layout change. The results are visual ideas rather than measured plans, which is fine for inspiration. The limits are pricing transparency and depth. Prices and credit packs are shown after sign-in in some cases, so check the cost before generating many images. RoomGPT also does not build a measured floor plan, so pair it with Planner 5D or Homestyler when you need dimensions and a shopping plan.

Planner 5D is the all-rounder for people who want to move from an idea to a plan. You can draw a floor plan in 2D, view it in 3D, add furniture from a large catalogue, and render the result for a realistic preview. AI tools help recognise plans and generate rooms, which speeds up the early stages for renovation projects. The free plan covers core planning, while premium features, extra catalogue items, and higher-quality renders sit behind a subscription. Planner 5D suits homeowners planning a renovation, renters testing layouts, and anyone who needs to check whether furniture actually fits before buying.

Homestyler offers one of the most generous free plans in this list, with unlimited 1K renders and a large free furniture library. That makes it a strong pick for users who want to design in 3D without paying up front, whether for a single room or a whole home. Floor planning, 3D modelling, and moodboard tools cover most home projects in one app. Paid plans add higher-resolution renders, pro tools, and extra catalogue access, which matter for professional presentations. The interface also takes a little time to learn for advanced modelling, though basic room design is approachable. Homestyler fits budget-conscious designers who want a capable free 3D tool.

Interior AI is built for fast style exploration, turning a room photo into many style variations in minutes. That breadth helps homeowners who are unsure which style they like, and agents who need staging images for listings. Sketch-to-render options also help designers turn a rough idea into a visual concept for clients. There is no permanent free plan, only a trial or limited free allowance depending on current terms, and higher-volume plans are priced for professionals. Interior AI suits users who need many variations quickly and are willing to pay for volume, rather than casual users who want one free redesign.

REimagineHome focuses on photorealistic results, which matters when a staging image will be used in a property listing or a client presentation. It covers interior redesign, virtual staging, object removal, and exterior visualisation, so agents and homeowners can test a room, a garden, or a facade in one tool. The conversational flow also helps users who are new to design tools. Free designs are limited, so regular use needs a monthly plan. REimagineHome suits real estate staging and serious redesign projects where image quality matters, while casual users may prefer a free trial elsewhere for a single idea.

Spacely AI stands out for its free allowance, with trial credits that let new users test many redesigns without a watermark in many cases. That generosity makes it a good first test for anyone who wants to compare AI redesign quality before paying. The workflow is fast, with style choices and room types that cover common home projects. It is a smaller service than Planner 5D or Homestyler, so support, tutorials, and catalogue depth are less extensive. Spacely AI fits users who want free, fast redesigns and are happy to move to a planning tool once they have chosen a direction.

Coohom is the professional end of this list, with AI floor-plan recognition, auto layouts, 3D modelling, and 4K rendering for client presentations. Retailers and designers use its branded furniture catalogues to show real products in a planned room, which helps clients approve a design before ordering. The presentation tools are stronger than consumer-only apps. Pricing reflects that professional focus, with a trial rather than a permanent free plan and paid tiers for regular use. Coohom suits designers, retailers, and serious renovators who need accurate, presentable 3D work, while casual users will find Planner 5D or Homestyler easier and cheaper.

IKEA Kreativ answers a practical question that generic AI tools cannot, which is how a specific IKEA sofa, shelf, or table will look in your actual room. You scan your room in the IKEA app, remove existing furniture in the view, and place IKEA products to test size, colour, and layout. Shopping integration then lets you buy the pieces you chose. The limit is obvious, since only IKEA products are available, so it cannot plan a room with mixed brands. Scanning quality also depends on phone, lighting, and room tidiness. IKEA Kreativ fits IKEA shoppers perfectly, and it pairs well with a planning tool when you need a full room plan beyond IKEA pieces.
