One world,
where everything grows
BuildChora's world model puts the physical world into a model — teaching robots to act in virtual, letting vehicles rehearse every extreme, and turning ideas into worlds in an instant.
Embodied AI
Training robots in the real world is costly and slow. BuildChora lets them practice day and night in virtual worlds — learning to grasp, walk, and collaborate — then transfer everything they learn to real hardware. From single-agent policies to multi-agent teamwork, every training run becomes reusable intelligence.
- Safe training — crash a thousand times in simulation without damaging a single robot
- Sim2Real transfer — virtual skills carry over seamlessly to real physics
- Multi-agent collaboration — hundreds of robots coordinate in one world
- Low-cost trial & error — training costs drop 90%, iteration goes from days to minutes
Train robot policies at scale in simulation, letting arms and bipeds rehearse grasping, walking, and collaboration until every motion is stable. Unlike real-robot training, there's no risk of damage — run thousands of parallel trials and compress months of training into days.
Autonomous Driving
Real-world driving can never cover every long-tail scenario. BuildChora synthesizes entire worlds so vehicles can rehearse rainstorms, fog banks, and collisions again and again — until every decision is reliable. This moves autonomous driving from "seen it" to "rehearsed it", pushing the safety boundary far forward.
- Long-tail synthesis — auto-generate extreme scenarios the real world rarely offers
- Sensor simulation — high-fidelity lidar, camera, and radar
- Closed-loop evaluation — end-to-end testing in virtual worlds
- Extreme weather — rain, snow, fog, night at the flip of a switch
Automatically synthesize the extreme conditions the real world rarely offers — from downpours and fog to sudden accidents — so vehicles rehearse every possibility in simulation. These cases are nearly impossible to collect on real roads, yet are often the root of accidents.
Games & Film
From generating a playable world in a single sentence to editing in real time, BuildChora compresses creative cost and cycle time to the extreme, freeing creators to spend their time on story rather than setup. Small teams get big-studio production power.
- World generation — one sentence creates terrain, ecology, and lighting
- Real-time editing — tweak as you generate, WYSIWYG
- Asset reuse — export generated content in standard formats
- Style transfer — swap between realistic, cartoon, or cyberpunk
Generate a complete world — terrain, ecology, and lighting — from a single sentence, collapsing months of work into minutes. Whether realistic landscapes or floating fantasy islands, the model understands your intent and shapes it instantly.
Digital Twin
Put an entire factory or an entire city into the model, synchronized with reality in real time. Every decision can be rehearsed in a virtual world before it lands in the real one. From equipment maintenance to city governance, unseen risks are seen first in the virtual.
- City-scale mirror — millimeter-level 3D reconstruction from buildings to pipelines
- Real-time sync — sensor data drives the twin world continuously
- Scenario rehearsal — disasters, congestion, accidents tested in advance
- Predictive maintenance — spot risk before failures happen
Rebuild cities from buildings to pipelines in millimeter-level 3D, mapping the whole city into a model that corresponds one-to-one with reality. From the skyline to a single pipeline's path, everything becomes computable spatial data.
