Best Free AI Interior Design Apps in 2026: 8 Apps Compared

IKEA Kreativ is the clearest free option on this list, because there is no separate design subscription to pay for. You can scan a room or use a saved design, then place real IKEA furniture in it and see sizes and prices in context. That product accuracy is genuinely useful when you plan to buy the pieces you place.

The limit is obvious, and it matters. Kreativ only shows IKEA products, so it cannot preview furniture from other brands or generate an unrestricted style makeover of your existing room. If your room already has pieces you want to keep, use Kreativ for the new items and a photo restyler for overall style ideas.

Planner 5D is our pick when you need a plan, not just a picture. The free plan lets you create and share unlimited projects, draw rooms to real measurements, and view them in 3D. That makes it useful for renovations, furniture placement and checking whether a sofa actually fits through a door and into a corner.

Free users get a limited catalogue, and the AI designer and full catalogue sit behind Premium, which is listed at $19.99 per month. That is still a fair trade for a planning tool, since the core measuring and layout work stays free, and you can upgrade for a single month when a project needs more furniture choices.

RoomGPT is the fastest way to answer a simple question, which is what a room might look like in another style. Upload a photo, pick a style, and you get redesigned variations without learning a 3D tool. The free tier gives one redesign, and credit packs start at $9 for 30 credits, with unused credits not expiring.

That simplicity is also the weakness. RoomGPT does not give you a measured plan you can edit, and a cluttered or badly lit photo can produce odd furniture or impossible layouts. Use it for inspiration and shortlisting styles, then move to Planner 5D or Homestyler when you need a plan you can act on.

Homestyler gives free users a workable 3D planner without forcing a trial that expires in days. You can build a room, place furniture and produce renders, which is enough for most DIY projects. The interface is aimed at home users rather than professionals, so the learning curve is gentler than full CAD tools.

Paid plans add higher resolution renders and more catalogue access, so check render limits before you promise a client a polished set of images. For personal planning and sharing ideas with family, the free plan is often enough, and it stays free rather than turning into a countdown.

REimagineHome sits between a quick restyler and a staging platform. It covers interior redesign, exterior concepts and virtual staging from uploaded photos, and it can suggest products similar to what appears in a generated image. That last point helps when a restyle looks good but you have no idea where to find the sofa in it.

The free allowance is small, so it works best as a test drive or for a single room. Real estate users and anyone staging several listings should price a paid plan early, and confirm export rights and watermark rules before using images in a public listing.

HomeDesigns AI covers more ground than most single purpose restylers, with interior redesign, exterior ideas and garden concepts in one account. That breadth suits homeowners planning a whole property refresh, and agents who need both indoor staging and kerb appeal images.

Read the trial terms carefully. Some trial routes ask for payment details and renew automatically, so set a reminder if you only want a short test. The credit model also means video and richer outputs can cost more than a single photo, so count credits per output, not just per month.

Spacely AI is aimed at people who revise designs repeatedly rather than generating one image and stopping. Its workflow supports iterative rendering, which helps design teams refine a concept through several rounds. Trial credits let you test that process before paying, which is useful for a team evaluating tools.

The trial has restricted exports, so do not plan a client delivery around trial output. If you like the workflow, compare the cost per finished render across plans, since different generation types consume different amounts of credit and the cheapest plan is not always the cheapest per image.

RoomSketcher is a straightforward planner for people who want a clean floor plan without a steep learning curve. Draw walls, add doors and windows, place furniture, and view the result in 3D. It is a good fit for estate agents, landlords and homeowners who need a clear plan for a listing or a renovation brief.

It is not an AI restyler, so do not expect it to transform a photo of your room. Pair it with RoomGPT or REimagineHome for style ideas, then build the winning layout in RoomSketcher so you have measurements and a plan a builder or buyer can actually use.
