Give your AI a body. three.ws is an open source (Apache-2.0), browser-native 3D AI agent platform. Type a prompt and Forge generates a textured 3D model, or drop a GLB you already have. Add an LLM brain, register on-chain, and embed anywhere: no plugins, no server uploads, no installs required.

Try it in 60 seconds: open three.ws/forge, type "a brass steampunk owl, full body", and download the GLB. Text→3D, image→3D, and sketch→3D — free draft tier, no account. Jump to the Forge section ↓

Want to build it with us? Your first contribution goes from clone to open pull request in about 15 minutes, with a full worked example. Every good first issue names the file to change and the command that proves it worked. Say hello in Discussions or Telegram.

Meet the avatar: a live 3D model, right here in markdown

Drag to rotate. This is not an image or a video: it is an interactive 3D model rendered natively by GitHub. The avatar was generated from a one-line text prompt on three.ws Forge (free tier), decimated to 1,200 triangles, and embedded as ASCII STL with readme-3d, our open-source toolkit for putting 3D models in any GitHub README, issue, or discussion.

Shortened. The full README is on GitHub.
