DecorAI is an AI interior design app for iOS, Android, and web that helps users redesign rooms, interiors, exteriors, and gardens from photos. It's the most-downloaded option on iOS and Android, but there are real differences between the major AI interior design apps and it pays to pick the right one for what you actually want to do.

Most people end up choosing between three categories: photo-based AI redesign apps (like DecorAI and RoomGPT), 3D planning apps (like Planner 5D and Homestyler), and traditional CAD tools (like SketchUp). This guide explains who each is best for.

How to pick

If you want to start from a photo of a real room — yours, a rental you're considering, or a listing — pick a photo-based AI app. DecorAI is the best-supported option in this category, with native iOS and Android apps in addition to web access. RoomGPT is web-only.

If you want to build a floor plan from scratch and place specific furniture, pick a 3D planner. Planner 5D and Homestyler are the leaders here. They take more time to learn but give you spatial accuracy.

If you need precision (architects, contractors, professional designers), use a traditional CAD tool. AI apps are not yet a substitute for SketchUp or AutoCAD when working drawings matter.
