About Convai
Convai is a specialized AI orchestration platform designed to provide real-time conversational intelligence for non-player characters (NPCs) and virtual assistants within 3D environments. By 2026, its architecture has evolved into a highly optimized pipeline that bridges Large Language Models (LLMs) with gaming engines like Unity, Unreal Engine 5, and NVIDIA Omniverse. The platform's technical core is built around a low-latency Speech-to-Speech (S2S) engine that handles STT (Speech-to-Text), LLM processing, and TTS (Text-to-Speech) in a unified stream, reducing perception-response time to sub-200ms levels. Beyond simple dialogue, Convai distinguishes itself through its Action API and Spatial Awareness features, which allow characters to perceive their environment and execute programmatic actions based on natural language commands. This enables a level of agency where an NPC can navigate a map, identify objects, and interact with the game world's physics or logic systems autonomously. Positioned as a mission-critical middleware for the Metaverse and high-fidelity training simulations, Convai provides the infrastructure for persistent, memory-capable digital entities that evolve through user interaction.
