Best AI Interior Design Tools

Planner 5D is the rare tool that covers both halves of interior design. Its core is a measured 2D/3D planner where walls, doors and furniture have real dimensions, so you can check that a sectional actually fits. On top of that it adds AI: upload a floor plan and it converts it to 3D, and its AI Studio uses Google's Nano Banana models and OpenAI's GPT Image to restyle rooms from photos.

The free plan is useful on its own (unlimited projects, half the catalogue), and the yearly Premium plan at $59.99 is cheap for a renovation project. Photo restyles are good rather than best-in-class, and the full catalogue of items is generic rather than tied to real products you can buy.

Pick it if you are actually renovating and need things to fit. Skip it if you only want a quick mood picture of a new style.

Homestyler is a full 3D home planner with a generous free plan: unlimited 1K renders and a library of more than 100,000 models. It handles multi-floor homes, custom lighting and even plumbing and electrical layouts, and its AI tools help with floor planning, staging and video. Paid tiers raise render resolution to 2K and 4K and add AI credits.

The learning curve is steeper than photo-restyle apps, and the AI features feel added on rather than central. Pricing is shown in local currency and varies by region.

Pick it if you want a free, detailed 3D plan. Skip it if you want a one-click makeover from a photo.

REimagineHome is built for people who need dependable, repeatable results, such as agents staging a listing or designers showing a client options. Its Pro plan adds incremental editing (change one thing without redrawing the whole room), reference-photo control, batch processing and "real products" matching that finds purchasable furniture similar to what the AI placed. Chatting with the design assistant is free; you only spend credits on images.

The $14 Essential plan is limited to older tools and 30 credits, so serious users will need the $49 Pro plan. It is not a measured planner.

Pick it if you stage properties or present options to clients. Skip it if you are a homeowner who needs a floor plan.

HomeDesignsAI covers interiors, exteriors and gardens, with more than 160 styles and a "structure-lock" mode that the company says keeps walls, windows and layout exactly as they are. It adds one-click video walkthroughs, 2D-to-3D floor-plan conversion, virtual staging and furniture shopping, so it is broader than most photo tools. The vendor reports 2.78 million users and displays a 4.8 Trustpilot rating from over 2,400 reviews.

Plan prices are only visible after sign-up, which makes comparison harder, and its floor-plan feature is not a full measured planner like Planner 5D.

Pick it if you want lots of styles for inside and outside the house. Skip it if you need exact dimensions.

Spacely AI is aimed at professionals. It plugs into SketchUp, Revit, AutoCAD and Rhino, so you can turn a rough 3D model into a photoreal render without a separate rendering engine. The Studio plan adds 4K downloads, and the Agency plan adds team seats and an API. The free trial is unusually fair: 40 credits, private mode, a commercial licence and no watermark.

For homeowners it is more tool than needed, and subscription prices are only shown at checkout. Top-up credits never expire, which is helpful for irregular project work.

Pick it if you already design in CAD and want fast renders. Skip it if you just want to see your living room in a new style.

Google's image models in the Gemini app have become a free rival to paid restyle apps. Upload a photo of your bedroom and ask for "warm Japandi, oak floor, linen bedding, keep the window and radiator exactly where they are" and Nano Banana usually keeps the room's structure while changing the finishes convincingly. You can then keep editing in plain language: swap the rug, try a darker wall.

It has no measurements, no floor plans and no furniture catalogue, so it can place a bed that would never fit. Several paid tools here, including Planner 5D, now run Google's models under the hood, which shows how strong they are.

Pick it if you want to test ideas for free. Skip it if you need dimensions or listing-ready staging in bulk.

Interior AI, from Photo AI creator Pieter Levels, was one of the first photo-restyle apps and remains a fast, capable one. It offers 55+ styles and several modes, including virtual staging of empty rooms, sketch-to-render, SketchUp rendering and 3D walkthrough videos. Even the entry Pro plan allows 1,000 designs a month, so it suits agents and designers who churn through many rooms.

There is no free plan, and $49 a month is a lot for a homeowner doing one room. A handful of Trustpilot reviewers also complain about cancelling subscriptions, so set a reminder if you only need a month.

Pick it if you need hundreds of renders a month. Skip it if you are redesigning a single room.

ChatGPT is a good design sounding board. You can upload a room, ask for three style directions, then talk through paint colours, budgets and where to buy similar pieces in the same chat. The images are attractive, and Images 2.5 (September 2026) made them faster.

In our reading of user reports, it is more likely than Gemini to redraw the room rather than edit it, shifting windows or changing the ceiling. It has no measurements or staging workflow.

Pick it if you want ideas and advice together, for free. Skip it if your listing photos must stay true to the real room.

RoomGPT helped start the AI room-redesign trend and says it has more than 4 million users. It is very simple: upload a photo, pick a room type and theme, and get a redesign. That simplicity is still its appeal for people who do not want to learn anything.

Newer tools have passed it. Structure preservation and realism trail Gemini and the specialist apps, and it lacks staging, video, floor plans and style depth. Free general models now do the same job at no cost.

Pick it if you want the simplest possible makeover tool. Skip it if you want the best quality; try Gemini first.
