Echo-3

Echo-3 is SpAItial's latest world model, launched 2026-10-27 with the SpAItial Capture app. Capture a real space on your phone; Echo-3 reconstructs a high-fidelity, metric-scale 3D environment—keeping what you scanned and filling gaps with world priors, with an emphasis on clean geometry.

Announcement: spaitial.ai/blog. Site: spaitial.ai. Official @SpAItial_AI posts drew strong engagement in-window. Prior models: Echo-1 / Echo-2 (text/image → explorable 3D worlds).

Product points

1. Input: phone capture (blog highlights iPhone space scans); output: enterable real-world-scale 3D worlds.
2. Vs pure geometry: Echo-3 uses priors about how the world looks to complete missing regions more coherently.
3. Scale story: single rooms through multi-floor buildings, outdoor and public spaces.
4. Lineup: Echo-1/2 lean generative explorable worlds; Echo-3 leans faithful real-space reconstruction plus a consumer/capture app.

Why this radar term

Distinct model name Echo-3 with same-day official blog + X launch evidence; Echo line was not in radar_leads.

Try it

1. Entry points: https://spaitial.ai/ and https://spaitial.ai/blog (Introducing Echo-3 and the SpAItial app)
2. Follow official capture tips; a 2026-09-27 tutorial covers floors, ceilings, corners, and close-ups
3. Developer API: site mentions Echo APIs for persistent 3D Gaussian Splat worlds (check current docs)

Good fit

• Teams needing indoor/architecture digital twins, spatial content, or robot sim scenes
• Creators following phone-to-metric-3D pipelines

Caveats

• Capture quality depends on coverage and technique
• Platforms (iOS etc.), availability, and pricing follow SpAItial's site
