Which AI tool is best for interior and architecture design?

To try looks on your own home, start free: upload a photo of the space to the Gemini app and ask it to restyle it, or use Interior AI, which redesigns a space from one photo in more than 55 styles and stages empty homes, with a Pro plan at $390 a year for 1,000 staged photos a month. To plan a real layout with measurements, Planner 5D is free for floor plans and 3D views, has an AI floor-plan converter, and costs ₹425 a month or ₹5,100 a year for Premium in India. Architects and interior designers who need proper 3D models use SketchUp, from $10.75 a month billed yearly for Go on iPad and web and $33.25 for Pro on the desktop, with photorealistic AI renders in its Studio plan. An AI picture shows a mood, not a buildable design: furniture sizes, wiring, plumbing and load-bearing walls still need a designer or architect to check. Rule: Gemini or Interior AI to choose a look, Planner 5D to plan it, SketchUp to draw it properly.
