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.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
