AI-native spatial builder. Say what you want and it appears; worlds persist, stay editable and go with you from iPhone to the browser to Apple Vision Pro.
Portals is an AI-native spatial builder: describe what you want and it appears in the scene. Worlds persist and stay editable, so you return to one and change it rather than rebuild it — on iPhone, in the browser and on Apple Vision Pro.
- Voice-driven authoring — speak the scene into being, no code.
- 360+ source-agnostic real-time VFX at 60 fps on an iPhone 14 Pro, with a reported 2.7–4.1× speedup.
- Persistent, editable scene state across sessions and devices.
- Gaussian splatting, photogrammetry and volumetric capture alongside generative AI.
Built at H3M, where James A. Tunick is President and Principal Engineer. Lead author of its IEEE/CVF CVPR 2026 Workshop paper on 4D world models, and first named inventor on the companion U.S. provisional patent.
