Spheroid Universe is a tool that allows users to create AI avatars in augmented reality. These avatars can be used for various purposes such as business, education, advertising, and fun. Users can create an avatar by selecting a space, 3D model, adding personality and training it to communicate with users. The avatars can talk to users through voice chat and understand natural language. Spheroid Universe also offers a dialogue tool and XR Hub augmented reality app to publish and invite people to visit the avatar in the real world.
