Scanning a real room usually means choosing between a quick capture full of holes and a slow one that takes real care. SpAItial’s new Echo-3 model, released October 27 with an iPhone app, is built around the quick version: capture a space for a few minutes, then let the model finish what the phone missed.

What changed

Earlier Echo models worked from a single image or a text prompt. Echo-3 starts from a capture of an actual place. SpAItial says it rebuilds the scene from what you recorded, fills the missing areas to match their surroundings, and keeps dimensions and distances true to the real space. It lists homes, classrooms, factories, equipment, outdoor spaces, and multi-floor buildings as targets.

The details so far:

  • Capture. The app is out on iPhone, with Android listed as coming soon. Radiance Fields reports that LiDAR-equipped Pro iPhones get live coverage guidance and a dense point cloud preview, while other supported iPhones capture without those views.
  • Processing. Scans upload for cloud processing, and finished scenes can be explored, measured, and shared as a browser link.
  • Exports. Radiance Fields reports that one capture can export as SPZ, SOG, meshes, normals, and depth.
  • API. SpAItial says Echo-3 will be available to enterprise customers through an API.

Why it matters for designers

If you do environments, architectural visualization, set extensions, or product scenes in real locations, a quick, to-scale scan is a handy starting point. Think of a venue you need to block out for an event, or a room you want as a reference for a 3D scene, without booking a dedicated capture.

Mesh and splat exports could also make the result useful outside SpAItial’s own viewer. That depends on which exports you can actually reach, though, as you’ll see below.

What to watch out for

The terms are the first thing to read, especially for client work. As of the version updated October 27, uploads, scans included, come with a broad, permanent license to SpAItial and can be used to train its models. Neither the terms nor the privacy policy offers a dedicated opt-out, though the policy does give a general right to object to processing based on legitimate interest. The privacy policy does say your content isn’t shared with third-party model providers for their own training. A scan of a client’s factory or someone’s home is sensitive material, and the terms have you promise you hold the permissions for what you upload, so get them first. The sidebar has the details, including why the Standard plan won’t cover paid work.

The quality claims are SpAItial’s own. It compared Echo-3 against Polycam, KIRI Engine, and Niantic Scaniverse on one scene, and Radiance Fields notes that it hasn’t published benchmark figures. We haven’t tested it either.

Filled-in areas deserve some caution. SpAItial doesn’t say how accurate they are, and its terms don’t warrant that generated content is accurate, so we wouldn’t trust a measurement that lands on a part the phone never saw.

Radiance Fields also points out that the launch materials don’t say which exports are available in the app, the web app, or the API. If you need a mesh in your own tool, confirm you can get one before you build a job around it.
