X3D Copilot

A spec-grounded, AI-assisted X3D 4.0 editor that runs entirely in the browser: live X_ITE rendering, validation against the official X3D 4.0 schema and the X3D Unified Object Model, an X3D-native transform gizmo, multi-format import, and an AI co-author that can only act through validated tools.
