What is the best AI interior design app?
It depends on the job. To redesign a room from a phone photo, RoomGPT (iOS and Android) is built for exactly that. For floor plans and 3D layouts, Planner 5D or Homestyler. For real estate virtual staging, Interior AI or ReimagineHome. For designers turning sketches and 3D models into renders, Spacely AI.

How we compared
We read each tool’s official website, pricing page and, where one exists, its App Store listing on 12 October 2026. Where a company does not publish a price, we say so instead of quoting a third-party estimate. Web and in-app prices often differ, so we note which one we quote. We make RoomGPT, which is listed first because it is ours, not because of a ranking. Interior AI was re-checked on 29 October 2026 after it changed its pricing.
Questions, answered
Is there a free AI interior design app?
- Most have a free tier or trial. RoomGPT includes 2 free designs, ReimagineHome 5 free designs and Spacely AI 40 free credits, and Planner 5D and Homestyler have free plans with limits.
Which AI interior design apps work on iPhone and Android?
- RoomGPT, Planner 5D, Homestyler and Decor8 AI all have iOS and Android apps. Interior AI, ReimagineHome and Spacely AI are web tools.
Is RoomGPT the same as roomgpt.io?
- No. roomgpt.io is a separate web tool by a different developer that started as an open-source project. The RoomGPT app on the App Store and Google Play, and this website, are a different product made by Hbrothers L.L.C.
Do AI interior design apps keep my room’s layout?
- Photo-based apps like RoomGPT keep your walls, windows and doors and change the furniture, materials and colors. Planning apps like Planner 5D build a new 3D model from your measurements instead.
Can I buy the furniture shown in an AI design?
- Usually not directly, because the furniture is generated. In RoomGPT you can tap a piece to run a Google image search and find similar products to buy.
