SpAItial
Frontier lab for world models

SpAItial is building physically-grounded world models

Our Echo model family outputs persistent 3D worlds that you can explore in real time. Read the Echo-2 announcement.

Step inside this world generated by Echo-2

This is a persistent world created with Echo, rendered interactively in your browser, with camera control over a stable 3D space. You can move through the world and explore it.

Create, edit, and share worlds.

The SpAItial app allows you to explore and build with Echo: You can generate worlds from images, text, and panoramas. Edit, share, and view worlds created with Echo.

  • Image to World

    Turn any image or 360° panorama into a 3D explorable world.

  • Text to World

    Generate 3D worlds from a text prompt.

  • Edit & Refine

    Sculpt, paint, and quickly refine your world with powerful tools.

  • Export Anywhere

    Export to popular 3D formats (SPZ, PLY, SOG, Collision Meshes, etc.)

  • Share Instantly

    Share a link and view in the browser

For developers

Build with the SpAItial API

The API is direct access to Echo for agents, tools, simulations, creative systems, and any product that needs generated Gaussian Splat worlds.

One request to Echo

Submit an image, prompt, or panorama and receive an async world generation job.

3DGS deliverables

Request SPZ or SOG Gaussian Splat outputs that are ready for real-time viewers.

Webhooks for async worlds

Subscribe to delivery events instead of polling—fire and forget.

Agent-ready API

Put spatial generation inside tools, agents, simulations, and creative pipelines.
