Convai is a next-generation AI-driven conversational character engine designed for games, VR/AR platforms, simulations and metaverse environments. By combining natural language understanding, speech recognition and generative AI, Convai enables developers to create NPCs (non‑player characters) that can hold dynamic conversations, respond intelligently to player actions and adapt to evolving storylines. Unlike traditional scripted dialogue systems, Convai provides natural dialogue, contextual understanding, memory, voice interaction, navigation and object manipulation capabilities for fully immersive game and virtual world experiences. Convai integrates with Unity, Unreal Engine, Roblox, NVIDIA Omniverse and custom engines, making it a top choice for developers building lifelike AI characters and autonomous virtual agents.
