You can use Convai to build conversational non-player characters and interactive avatars for games, virtual reality, and training simulations. It gives virtual characters the ability to see, hear, understand, and interact with players in real time through natural speech and gestures. You can configure backstories, upload knowledge bases, define actions, and assign emotional states to your characters. The service plugs directly into popular game engines like Unreal Engine and Unity, allowing you to bring lifelike dialogue and dynamic responses into any custom 3D environment.
