Convai

Convai lets you create and connect intelligent characters to your virtual world with ease. The tool has an intuitive interface which lets you develop characters and NPCs with unique backstories, voices, and expertise, and even test them out in a playground. Using plugins, you can seamlessly integrate your characters with various game engines such as Unreal Engine, Unity, Nvidia Omniverse, and Roblox. Convai also enables open-ended, voice-based conversations and actions with your created characters.
