Simbrace Worlds Real-time 3D world generation

Real-time 3D world generation

Generate your 3D worlds in VR.

A sentence becomes an ocean. A thought becomes a planet. Simbrace builds explorable 3D worlds around you as you speak, from a tropical reef to a city skyline to a road that doesn't exist yet.

Early access is opening to creators, studios, and builders.

From words to worlds

Describe it. Step inside it.

You speak, and the world takes shape in front of you. Pixels become form, form becomes a place you can walk into. Reefs, skylines, canyon roads, whole planets, built the moment you picture them.

  1. 01 / Spark

    Say it

    Describe a place, a mood, a moment, and the world starts building from your first word.

  2. 02 / Wonder

    Watch it form

    Geometry, light, and motion assemble in real time into something photoreal and alive.

  3. 03 / Freedom

    Go anywhere

    Dive an ocean, surface into golden light, race a road as it builds beneath you. One world flows straight into the next.

Infinite worlds. Instantly yours.

How you build

  1. Speak it or type it

    Use natural language as the interface. Say what you want, or type the command when precision matters.

  2. Iterate like a REPL

    Prompt, inspect, adjust, repeat. A world does not have to be designed in one perfect sentence.

  3. Scope the command

    Change the cliff without changing the ocean. Add an object without rebuilding the whole scene. Keep continuity while you iterate.

A person wearing a VR headset gestures with both hands as a glowing wave and wireframe structures reshape the space around them into a furnished room and landscape.

Example command session

> create a coastal cliff at sunrise, Mediterranean light, narrow path, waves below
> add a wooden lookout deck and two avatars near the rail
> make the wind stronger, keep the same coastline
> turn the path into a playable route to the lighthouse

The point is not a single perfect prompt. The point is a loop: describe, inspect, refine, continue.

What you can drive by command

  • Environments. Terrain, coastlines, rooms, roads, islands, planets, interiors.

  • Atmosphere. Time of day, light, weather, density, mood, scale.

  • Objects. Props, landmarks, paths, platforms, tools, points of interest.

  • Avatars. Characters that can inhabit the world, guide users, or become part of a scenario.

  • Continuity. Keep what matters while changing the next layer.

Current technical direction

  • Target devices. Meta Quest 3/3S, Apple Vision Pro, iPhone, Android, mobile phones and tablets, PC computers (Mac, Windows).

  • Control. Spoken and typed natural-language commands.

  • Generation. Real-time world creation and modification.

  • Persistence. World state and continuity under active development.

  • Backend. In progress.

This is an early build. Some parts are working now, some are being tested, and the backend is still in progress. We are opening access to builders who want to help shape the product while it is still forming.

Who it's for

  • Builders and tinkerers. People who want to test the edges of command-driven world creation.

  • Creators and studios. Teams exploring fast spatial prototyping and previsualization.

  • Training and simulation teams. Groups that need worlds, scenarios, and guides to change faster than traditional production allows.

  • Technical partners. People interested in the engine, workflow, and future platform layer.
