AI SYSTEMS

AI Systems

Intelligent game AI that runs entirely on-device. No cloud dependency.

BEHAVIOR

NPC Behavior

Behavior tree system with composable nodes, state machines, utility scoring, and runtime debugging. Genre-aware presets for combat AI, patrol routines, trading NPCs, and more.

Key benefit: Ship believable NPC behavior in hours, not weeks.
VOICE

Voice Commands

On-device speech recognition and synthesis with zero cloud dependency. Low-latency voice interaction for NPCs, UI navigation, and in-game commands. Privacy-first — audio never leaves the device.

Key benefit: Voice-driven gameplay without cloud costs, latency, or privacy concerns.
NPC

NPC Intelligence

On-device small language model powering NPC memory, personality, and contextual dialogue. NPCs remember past interactions, adapt tone to player behavior, and generate unique responses — all running locally.

Key benefit: Every player gets a unique story. No two playthroughs are the same.

Build Smarter Games

AI is not a plugin. It is the foundation. Every Raku game has access to navigation, behavior, voice, and NPC intelligence from day one.
