Convai

Convai is a highly-rated developer platform for creating NPCs with advanced multimodal perception in 3D game engines. These AI agents can see and hear their surroundings, then respond with human-like dialogue, voice, gestures, and contextually appropriate actions. Features include real-time voice interaction, knowledge bases for accurate responses, long-term character memory, and integration with Unreal Engine, Unity, and 3JS. The platform addresses LLM hallucination through knowledge base grounding.
