Convai

Convai lets creators and developers build conversational 3D AI characters for games, virtual worlds, training, websites, and XR.

Convai provides tools for creating AI characters with natural-language conversation, voice, multimodal perception, memory, knowledge bases, personalities, guardrails, and actions. Characters can be deployed in browsers, custom 3D environments, Unity, Unreal Engine, and other applications through APIs.

It is used for game NPCs, virtual guides, brand representatives, role-play training, social virtual worlds, kiosks, and XR simulations. Usage is limited by monthly interaction quotas and concurrency; higher quotas, premium model and voice interactions, long-term memory, and enterprise deployment options require paid plans.
