AI interior design generated by DecorAI — Japandi living room

DecorAI is an AI interior design app for iOS, Android, and web that helps users redesign rooms, interiors, exteriors, and gardens from photos. RoomGPT is a web-based AI room design tool that also redesigns rooms from a photo. The two are often compared because they target the same core use case.

The biggest practical difference: DecorAI has native iOS and Android apps in addition to a web version, and supports exterior and garden design alongside interior rooms. RoomGPT is web-only and focused on interior rooms. Both tools change over time, so always check each product's current capabilities before deciding.
