Turn text, images, and videos into production-ready 3D assets in minutes
Describe an object or character in plain language and receive an editable 3D model, with prompt examples tuned for characters, props, and product concepts.
Upload a JPG, PNG, or WEBP reference and convert a 2D concept or photo into detailed 3D geometry in seconds.
Apply materials to an existing model using text prompts or reference images to produce PBR-styled surfaces instead of flat color meshes.
Automatically generate clean skeletons and skin weights for characters, aiming to deliver animation-ready files without manual rigging work.
Browser-based 3D design and animation with real-time team and AI agent collaboration
Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.
Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.
Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.
Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.
Generates 3D assets rapidly from text or images, but focuses on object creation rather than interactive web scene composition.
