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.
Build Together
Host a world on your network and let friends join with a PIN. Everyone explores in their own window and asks your AI to build where they're looking — joiners can only edit the scene, never your machine. Learn more
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.
The LocalGPT family
Open source apps that turn what you type, write, and listen to into places you can explore — all running locally.
LocalGPT Gen
Describe a place and walk into it — geometry, materials, lighting, behaviors, and sound. Build alone or host a session and build with friends.
