Best AI Room Design Apps in 2026: 8 Apps Compared

Planner 5D is the most complete planning tool on this list for a homeowner who wants to do more than look at a pretty picture. You can draw walls, set room sizes, add doors and windows, then place furniture and switch between a flat plan and a 3D view. The free plan lets you create and share unlimited projects across web and mobile, with a basic catalog to start from.

Premium starts at $19.99 per month, or $59.99 per year on annual billing, and it adds the AI Designer, the full furniture catalog, and a set number of renders each month. That makes it a good step up when a free project starts to feel limited, but it is not needed just to test a layout. Planner 5D will not replace a contractor drawing for building work, yet it is a strong way to test a layout before you talk to one.

RoomGPT became well known because it does one job with very little setup. Upload a photo of a room, pick the room type and a theme, and the app returns a restyled version of the same space. Credit packs are sold in bundles, with a small free allowance to test the tool, and unused credits do not expire under the current credit model.

That simplicity is also the limit. You cannot move a sofa, change a wall, or get a shopping list from the result, and the generated room may change details such as furniture size or window placement. Use RoomGPT for early ideas and style direction, then move to a planning app when you need measurements. It is best for a renter or homeowner who wants to see options fast, not for a full remodel plan.

Homestyler sits between a quick photo tool and a professional design program. You can start from a floor plan, build a room in 2D, view it in 3D, and try different furniture arrangements without moving anything in real life. That makes it useful for a common question: will this table fit, and will the room still feel open with it in place.

The free version covers basic planning, while paid plans add more renders, assets, and design features. Check the current pricing page before you commit, because plans and limits can differ by platform. Homestyler fits a homeowner who is ready to plan a room properly, and who wants to share a visual plan with a partner, a landlord, or a contractor.

Less of a single AI app, Houzz is more of a design library with shopping built in. You can search real rooms by style, room type, and colour, save the ones you like, and follow links to similar furniture and decor. That link from idea to product is the main advantage, because a generated image alone does not tell you where to buy the sofa in the picture.

The app itself is free to browse and save ideas, while products are sold by retailers at their own prices. Houzz also offers design and visualisation tools, but photo restyling is not its main strength. Use it when you already like a look and need to find real items that match it, or when you want to show a designer a board of rooms you actually want to live in.

For people who care about measurements, RoomSketcher is the plan first option. You draw a floor plan to scale, add furniture, and view the result in 2D or 3D. That measured approach helps when you need to show a contractor where a wall sits, or when a buyer wants to see how a home flows from room to room.

The free tier lets you test basic planning, while paid plans add features such as high quality 3D photos and floor plan exports. RoomSketcher is less useful if you only want to restyle one photo in a new colour scheme, because that is not its main job. Choose it when accuracy matters more than a quick style experiment.

Interior AI follows the photo restyling model: upload a room photo, choose a style, and compare the new version with the original. It is popular with homeowners who want to test a look before painting or buying, and with agents who want a quick visual for a listing. The workflow is short, and you do not need design training to get a usable first result.

As with other photo tools, treat the result as a concept. A generated image may move furniture, change proportions, or add items that do not exist in your room. Check the pricing page for current plans and any free allowance, since credit and subscription models in this category change often. Interior AI is a good idea tool, not a measured plan.

Property sellers are the main audience for REimagineHome. Upload a photo of an empty or dated room, and the tool can furnish it virtually, restyle it, or show a cleaner version for a listing. That can help a buyer see potential in a room that looks bare in person, without the cost and effort of physical staging.

The key limit is honesty in a listing. Virtual staging should be clearly marked, so buyers are not surprised when they visit in person. Pricing is shown on the vendor site, with a free allowance or trial to test the tool. REimagineHome fits agents, landlords, and sellers who need listing images fast, and homeowners who want to test furniture in a room before they buy it.

Spacely AI keeps the process short: upload a room photo, pick a style, and view a redesigned version. That makes it a good fit for someone who does not want to learn floor plan software just to see whether a warmer palette or a simpler layout might suit a room. A clear, well lit, wide angle photo gives the best result, while a dark or cluttered photo tends to produce a less useful image.

Spacely AI does not replace a measured plan, and it does not provide a shopping list for the items in the generated image. Use it for early inspiration, then check sizes and products separately. For a quick style test before a weekend decorating project, that simple workflow is often enough.
