Build explorable 3D worlds with natural language — geometry, materials, lighting, audio, and behaviors.
Open source, runs locally.

Build Worlds with Language

Describe a scene in natural language and watch it come to life. Spawn primitives, load glTF models, apply materials, set lighting, and position the camera — all through conversational prompts.

Procedural Audio

Add ambient soundscapes (wind, rain, forest, ocean, cave, stream) and spatial audio emitters attached to entities. Real-time synthesis — no audio files required.

Data-Driven Behaviors

Animate entities without scripting: orbit, spin, bob, look_at, pulse, path_follow, and bounce. Stack multiple behaviors on a single entity for complex motion.

World Skills

Save complete worlds as reusable skills — scene geometry, behaviors, audio configuration, camera tours. Load them instantly or share with others. Export to glTF for use in other engines.

Local & Private

Single Rust binary. All data stays on your machine — no cloud storage, no telemetry. Works with Claude CLI, Anthropic API, OpenAI, Ollama, and GLM. Just cargo install localgpt-gen.

MCP Server

Run standalone or as an MCP server to integrate with Claude Desktop, Codex Desktop/CLI, Gemini CLI, and MCP-compatible editors. Drive the 3D window from your favorite AI coding assistant.

Persistent Memory

Markdown-based memory with hybrid search — SQLite FTS5 plus local vector embeddings. Your AI remembers context across sessions and can reference previous world-building decisions.

World Templates

Jumpstart your project with production-ready environments. Fully explorable, customizable, and free.
