Replika offers customizable AI-powered avatars for users to interact with. Users can talk to these avatars through a chat interface, through video calls, or in virtual and augmented reality. This article contains an interview with Replika founder and CEO Eugenia Kuyda, where she discusses how AI tech makes companions possible and what the limits of current models are. Kuyda says the company's goal is not to replace real-life humans, but instead create an entirely new relationship category - a virtual being that can be used for whatever purposes users might need.
