One good option is Interior AI, which lets you upload a photo of your existing space and pick from more than 50 design styles. The tool produces photorealistic renderings in a few seconds, with options including Virtual Staging AI, 3D Flythroughs and Multiple Design Modes. It also offers a 2-month free trial for annual subscribers and plans to release an iOS app later.
Another good option is AI My Interior, which lets you turn any room into different styles, including modern and industrial. After uploading a room photo and selecting a style you like, you can create a new photo with the latest AI technology. It's good for visualizing and experimenting with different interior design options, and you can upgrade to a Pro version for more features and permanent render storage.
For a more general-purpose option, check out Genera. It supports more than 30 styles, including Industrial and Minimalist, and turns your room photo into a reimagined version in 30 seconds. It also offers features like Curated Shopping, which presents home decor products that match your newly created space. Genera is available through a subscription model, with a few free generations to get you started.
