Best AI Interior Design App Free in 2026

RoomGPT asks for a photo, a room type, and a style, then returns a redesigned version of that same room. That simple flow is why it works well as a first test. You can check a style in minutes, before you spend money on paint, fabric, or furniture, and you do not need design skills to get a useful result. The output is an image, not a plan, so treat it as direction rather than a finished specification. The limits matter too. RoomGPT does not keep your layout as an editable project, and it does not link the furniture it shows to real products you can buy. If the render changes a window, a door, or a fixed feature, you will need to correct that yourself. Use it for inspiration and for shortlisting styles, then move to a planner when you are ready to measure and buy.

Planner 5D is the practical choice when you want to plan a room rather than just look at a picture of one. You can draw a floor plan, place furniture, and switch between 2D and 3D views to check walkways, door swings, and storage. That planning step catches problems that a pretty render hides, such as a sofa that blocks a door or a table that leaves too little space to pull out a chair. The free plan covers unlimited projects with about half the furniture catalog, which is enough for many home projects. Paid plans add the full catalog and higher quality renders. If you want AI image generation inside an editable project, check the current plan details before you pay, because AI features are not all on the free plan. For layout work, this is the most useful free starting point in this list.

Homestyler gives you a full 3D design workspace with a free basic plan, which makes it a good second step after a photo tool sparks an idea. You can build walls, add windows and doors, and furnish the space from a large library of models. The ability to view the room from different angles helps you judge light, sight lines, and how crowded a layout feels. The trade off is effort. You build the room yourself instead of uploading a photo and getting an instant restyle, so the first project takes longer. Free AI credits are also limited, so do not expect unlimited AI renders on the basic plan. If you enjoy hands on planning and want renders you can adjust, Homestyler is a strong free option.

REimagineHome stands out for its conversational approach. You can describe changes in plain words and ask for a new version, which feels closer to briefing a designer than picking from a fixed menu. It also supports virtual staging, so an empty room can be shown furnished, a useful step for sellers and landlords who want listing photos to read well. The free offer is a trial rather than ongoing free use, with five designs and no card required in current listings. After that, you need a paid plan for continued work and for features such as reference photos and shoppable products. Try it on one real room first, and save the designs you like before the trial ends.

Spacely AI is aimed at people who need a clean render to share, including designers and agents. The trial credits come without a watermark in current listings, which makes the output easier to use in a presentation or a listing draft. It accepts photos and sketches, and it can furnish empty rooms, relight scenes, and support 3D workflows. The limit is the same as with most photo tools: the trial is finite, and the furniture shown is generated rather than linked to a store. That makes Spacely AI good for visual direction and client discussion, but not for building a buy list. If you need watermark free output for a small number of rooms, start here and use the credits on your best photos.

Interior AI offers one of the widest style libraries in this group, from Scandinavian and coastal looks to Art Deco and Japanese Zen. That range helps when you are not sure what you like yet and want to compare several directions for the same room. Higher tiers add virtual staging for empty rooms, which is useful for property work. The main drawback is access. Current listings describe a trial rather than a lasting free plan, so check the pricing page before you start a project. The tool also favors looks over feasibility, so a render may show a layout that would not work in a real room. Use it to explore styles, then check measurements, storage, and light in a planner before you commit.

HomeDesigns AI is useful when a project goes beyond one room. It covers interior redesign, exterior looks, and garden ideas in one place, so a whole property refresh can stay in a single workflow. That breadth suits homeowners planning a larger update, and it also helps agents who need consistent visuals across indoor and outdoor shots. Free access is limited and terms vary by offer, so treat the trial as a test rather than a long term plan. Credit costs also differ from tool to tool, which makes direct price comparison tricky. Start with your most important room, note what each credit buys, and only pay once you know the output quality suits your project.

IKEA Kreativ is different from every other tool here, because the furniture it shows is real and sold by IKEA. That matters when you move from inspiration to buying. You can place true to scale pieces in a room view and check whether a wardrobe, sofa, or storage unit fits the space you actually have. For small rooms, that scale check alone can save a costly return. The limit is scope. You are working inside the IKEA catalog, so it will not help you compare brands or plan a room around pieces you already own from other stores. A full 3D scan also needs supported hardware. Use Kreativ to test IKEA pieces, and use a planner for the full layout when your room mixes brands.

DecorMatters is built for phone users who want to see furniture in their own room through augmented reality. You can try a piece in place, move it, and get a sense of scale and color before you order. The app also includes design ideas from other users, which can help when you are stuck on a starting point. AR placement depends on your phone, your lighting, and a clear floor view, so results will vary from room to room. Some deeper features and catalog items sit behind paid plans. Treat AR as a helpful check, not a final measurement, and confirm dimensions on the product page before you buy.
