Interior AI is a good place to start. You can reconfigure and virtually stage interiors with a photo upload, with more than 50 design styles and photorealistic renderings in seconds. It offers Virtual Staging AI, 3D Flythroughs and Sketch Conversion. It also offers a 2-month free trial and plans to release an iOS app.
Another tool worth a look is Virtual Staging, which turns a bare room into a virtually staged one. It produces results in less than 10 seconds, with prices starting at $16 per month for 6 photos. It offers unlimited revisions and can handle multiple rooms, so it's good for real estate agents, property owners and interior designers.
REimagineHome is another good choice, offering photorealistic imagery for custom interior design and virtual staging. With several pricing tiers and a free trial, it's good for real estate agents, interior designers, photographers and developers, with fast turnaround times for high-quality results.
