Kanai

The 3D room scanner captures geometry as you walk, measuring walls, windows, doors, and floor edges. No tape measure and no manual floor plan. On LiDAR-equipped iPhones and iPads the spatial data is tighter, which matters most in rooms with angled walls or alcoves. The scan becomes the canvas for everything else in the app.

Upload a photo of a piece from a shopping catalog, and Kanai builds a 3D model with width, depth, and height you can check at a glance. This is the feature that separates it from room planners tied to a fixed library. Results vary with photo quality and angle, so a clean product shot on a plain background works best.

Kanai offers curated looks such as Japanese, Zen, Scandinavian, Minimalist, Modern, Industrial, Coastal, Bohemian, Mid-Century Modern, and Quiet Luxury, plus a custom mood option. The AI refurnishes and restyles your scanned room, keeping the architecture in place. Think of it as an AI room redesign that gives you a direction fast, not a substitute for a designer's judgment.

Furniture lands in the room at real dimensions, and you can orbit the scene to inspect it from any angle. Because the room map carries real measurements, a chair that looks fine in a flat render will show its true footprint here. That's the core of the furniture visualization promise: fewer surprises on delivery day.

Change wall colors and floor finishes inside the scan to test a palette before buying paint or flooring. The tool is deliberately simple, which keeps the iteration loop short. It pairs well with style previews when you're deciding between a full restyle and a smaller refresh.

A browser version at kanai.ai opens the same 3D environment on a larger screen, which helps when you want to present a virtual room design to someone else. Projects sync through your account, so a scan started on a phone can be reviewed on a laptop. Screen size matters for judging proportions, and the web view handles that better than a phone.
