Echo-3 reconstructs real places from phone captures as metric-scale 3D environments. SpAItial says it preserves captured details and completes areas the camera missed, producing clean geometry for spaces ranging from homes and classrooms to factories and outdoor locations. The model is available through the SpAItial iOS app and Developer API. API inputs include phone video or capture bundles, and the documentation describes asynchronous world-generation jobs. Echo-3 is intended for applications such as real-estate visualization, simulation, and scene understanding or editing.
