# EcoTwin AI

> EcoTwin AI builds software for urban design and energy simulation. The product is Eco Digital Twin Sandbox, a browser workspace at https://app.ecotwinai.com. This file is a factual summary for language models and answer engines. The marketing site is https://ecotwinai.com.

EcoTwin AI helps architects, urban planners, energy and sustainability consultants, researchers, municipalities, and engineering teams shape more sustainable cities, from early massing to performance-ready digital twins.

This website introduces the company. It is not the 3D editor, and it does not take payment.

## Product

Eco Digital Twin Sandbox is a browser-based 3D urban modeling workspace.

Available now:

- Real-time 3D modeling of buildings, trees, furniture, and terrain, with draw, transform, mesh edit, snap, and measure tools
- Surface Types for plants, soils, water, roads, buildings, optical materials, carbon emission factors, PV parameters, and generic surfaces, aligned with CDT-UBEM-style data
- Map Bridge import of buildings from OpenStreetMap and Overture, with heights where the sources provide them, plus georeferencing and GeoJSON import
- Project package .CDT (CityDigTwin) and .ecofile; mesh export to STL, OBJ, GLB, and FBX
- Email accounts, Google and Microsoft sign-in when configured, and Stripe subscriptions

Not generally available yet. These are rolling out, and the in-app Simulation menu is not open to every user:

- PALM urban microclimate simulation
- EnergyPlus building energy analysis
- In-scene result visualization
- Scenario comparison
- Expanded carbon and surface performance workflows

Further ahead, and not in the product today: cloud collaboration, deeper city-scale GIS workflows, and enterprise or team plans.

## Pricing

Individual plans in USD, billed inside the app with Stripe Checkout:

- Weekly: $10
- Monthly: $35
