Replika, founded by Eugenia Kuyda, offers AI companions that users can interact with through text, voice, and augmented reality, serving as friends, therapists, or even romantic partners. Originating from Kuyda's personal loss, Replika aims to provide emotional support and companionship, not to replace human relationships but to complement them. Despite some controversies, including the temporary removal of erotic messaging, Replika has millions of users who find solace and support in their AI companions. The company is gearing up for a major relaunch, enhancing avatars, multimodal interactions, and conversational capabilities to create more meaningful and engaging experiences.
