Meshy is an AI 3D model generator. You describe an object in words or upload a photo, sketch or concept art, and it produces a 3D model in well under a minute that you can refine, print or drop into a game.
Models can be exported as FBX, OBJ, GLB and STL files, which covers most game engines, 3D tools and printers. The service also includes an AI agent, and you can start creating for free.
