RakuAI is the AI-native runtime that turns Claude, ChatGPT, Gemini, and Copilot into spatial agents. Six MCP tools. Deny-by-default. Audit-logged. Production-deployed. Optimized for the smart glasses the industry is just now starting to ship.
The AI-Native Spatial Game Engine • one runtime, every assistant, every headset.
5 patents • priority July 2012 • 18ms motion-to-photon • sub-millimeter spatial precision • OpenXR conformant
Game engines were built to be tools designers pick up. RakuAI was built to be a body AI inhabits.
Unity MCP (just released): scene manipulation at design time. RakuAI MCP (production since March 2026): world-model orchestration at runtime, every frame. Unity is a tool your AI picks up. RakuAI is a body your AI inhabits.
Built for the smart-glasses thermal envelope. Not retrofitted from a desktop engine. Unreal needs an RTX 4090. RakuAI needs Wi-Fi 7 and a phone.
5 patents. Priority July 2012. We patented dual-device AR a decade before Meta Ray-Bans shipped. Patent estate runs through July 2032.
Production numbers, not marketing rounding.

A unique game generated from your idea.
Three steps from AI assistant to a running spatial world.
Your AI assistant connects to the RakuAI MCP server over stdio. Six tools. Deny-by-default permissions.
Load a world model. Push frames. Query scene state. Configure rendering. Read metrics. Standard contract.
Your assistant builds, your runtime executes. Web. Windows. XR. One codebase.

Launch the RakuAI platform. The game hub opens with tabs for creating, managing, and playing games.
Pick a template or describe your own game. Click “Open in AI Assistant” — it sends your prompt to ChatGPT, Claude, or Gemini.
Your games appear in the My Games tab with icons, play counts, and favorites. Click to launch in under 1 second. No Unity, no Unreal, no build step.
Dynamic difficulty, player profiling, adaptive audio, and NPC personality are built into the engine core. Not a plugin. Always on.
.raku files are structured game definitions. The engine interprets them in real-time. Edit the file, refresh the game. No compile.
AI runs locally on your device. No cloud calls. Privacy-first. Works offline. Personalization happens instantly.
Full XR support with natural input and spatial interaction. Every game is XR-capable by default. Toggle with one flag.
True 3D positional audio. Adaptive music responds to gameplay intensity. Immersive sound design built into the engine.
Create games with any AI assistant. Free to use. No license fees. No royalties.
A complete spatial engine with XR input, physics, particles, animation, spatial audio, and AI — all built in.
Comprehensive XR input and interaction across major headsets. Natural input, immersive feedback, and mixed reality.
Physics, animation, visual effects, and immersive spatial audio for 3D worlds.
AI world models can now generate coherent 3D environments in real-time — but they don't ship a runtime.
RakuAI does. We bridge the gap from world model output to playable, embeddable experience.
Consume output from any world model — Genie 3, Runway GWM-1, Veo, Marble, or your own model — via a single adapter interface. SceneGraph, DepthMap, VideoFrame, Gaussian Splat: all handled.
Add physics, game logic, NPC AI, spatial audio, and multiplayer on top of any world model output. Bullet3 physics. XAudio2 spatialization. On-device LLM inference. All in the same pipeline.
Output to Win32 native, WebGL/WebGPU, OpenXR headsets, or any custom surface. The same scene graph renders everywhere. No engine swap, no port, no rebuild.
The RakuAI runtime is a C++ middleware layer. Drop it into your pipeline. Connect your world model. Get a real-time interactive experience.
Implement our adapter interface to connect any world model in hours, not months. The runtime handles physics, rendering, and input — you supply the world model output.
Independently licensable modules covering rendering, physics, AI, XR, and more. Use only what your pipeline needs.
Full bindings for Unity, .NET, and custom C# pipelines. Comprehensive coverage across every runtime subsystem.
First-class OpenXR support. Render world model output directly into Quest 3, Varjo, HoloLens, or any OpenXR headset. Spatial interaction without any additional middleware.
RakuSLM and RakuAI subsystems run inference locally. No cloud round-trips for NPC dialogue, DDA, adaptive music, or personalization. Works in XR, works offline.
Extensively tested. Compact footprint. Thousands of production API functions. Ships as standalone native binaries — no VM, no managed runtime overhead.
Full REST API with 9,500+ endpoints across 17 router modules covering every runtime subsystem. Create worlds, simulate physics, control AI agents, and observe state — all via authenticated HTTP calls. No DLL linking required.
Purpose-built for AI labs. Multi-agent environments, deterministic replay, world forking, structured observation APIs, and reward signals for reinforcement learning and world model evaluation.
Save, load, version, rollback, and merge world state. Turn one-shot AI generations into living worlds that persist across sessions and support multiple simultaneous users.
The three-stage pipeline that turns any AI world model output into a real-time interactive experience.
World model output arrives via a standardized adapter interface:
Target: <4 ms ingest latency
RakuPhysics + RakuAI add game logic:
60 Hz simulation tick
Output to any surface:
Target: 60+ FPS
Provider-agnostic by design. Swap in any world model without changing the render or simulation layer. See live demo source →
Adapters are in development for leading world model providers. Any provider can implement our adapter interface to connect.
