Placy AR allows you to generate a 3D model of an object from a single photo using AI and explore it in augmented reality. Whether it’s an image of furniture from a marketplace, a picture from a distributor’s webpage, or a photo you took yourself – use AR to place the generated object in your real space and scale it accurately to see how it fits. This makes it easy to evaluate proportions, plan interiors, and test ideas before committing to a decision. You can also export generated models for use in other apps, design tools, or 3D workflows, making it easy to reuse, share, or refine them further.
