SpAItial has released Echo-3, a world model that turns a few minutes of iPhone capture into a gaussian splatting scene at real world scale.
SpAItial's original Echo arrived in December as a generator working from a single image or text prompt, and Echo-2 added scene decomposition and per object editing in April. Both started from a single image or prompt. Echo-3 starts from a walkthrough of a real space, and SpAItial describes it as treating reconstruction as a form of generation.
Echo-3 combines the capture with what the model has learned about how real spaces look. A quick phone pass leaves some surfaces barely visible and others missed entirely, so Echo-3 builds the scene from the captured frames, then fills the gaps to match their surroundings. In SpAItial's wording, the goal is to "preserve what you captured and complete what you missed." Reconstructions are metric, so distances and dimensions match the physical space, and SpAItial lists homes, classrooms, factories, equipment, outdoor spaces and buildings spanning multiple floors as targets.
Echo-3 ships alongside a new SpAItial app for iPhone. Scans are saved on the phone, then uploaded for cloud processing. On LiDAR Pro iPhones the app shows live coverage guidance and a dense point cloud preview, while supported non-LiDAR iPhones capture without those views. Finished scenes can be explored, measured and shared as a link that opens in any browser.
Processing is billed in credits, at 300 credits per recorded scan minute with a 900 credit minimum. The Standard plan includes 7,500 credits a month, or up to 25 scan minutes, for non-commercial use. Pro doubles that to 15,000 credits, up to 50 scan minutes, and adds commercial rights. Eligible new subscribers get the first month free.
SpAItial says one Echo-3 capture can be exported as SPZ, SOG, meshes, normals and depth. The launch materials do not specify which of those exports are available in the app, the web app or the API.
SpAItial compares Echo-3 against Polycam, KIRI Engine and Niantic Scaniverse on a single scene, captured along a similar path in each app, and says its result shows sharp surfaces with no visible floaters. The company calls Echo-3 state of the art for reconstruction quality but has not published benchmark figures.
Enterprise customers can also reach Echo-3 through an API, which SpAItial pitches for real estate visualization, simulation inputs, and scene understanding and editing by AI agents. Agents were already a target when SpAItial shipped a Claude plugin and hosted MCP server for its Echo models in June.
The SpAItial app is available now on iPhone, with Android coming soon.
