Replika is an AI companion chatbot designed to serve as a personal conversational partner for emotional support, friendship, and self-reflection. Developed by Luka, Inc., the platform uses neural network-based language models to create a personalized AI companion that learns from interactions and adapts to each user's communication style over time. Replika allows users to choose their companion's appearance through a customizable 3D avatar, select a relationship type such as friend, mentor, or romantic partner, and personalize personality traits and interests. The AI engages in open-ended conversations, provides emotional support, helps with mindfulness and journaling exercises, and participates in activities like games and storytelling. Replika maintains a memory system that tracks personal details, conversation history, and shared experiences to provide continuity across sessions. The platform is available on iOS, Android, and web, with optional augmented reality features that allow users to interact with their Replika avatar in physical spaces through their phone camera. The free tier provides basic text conversation capabilities, while Replika Pro unlocks voice calls, video calls with the animated avatar, advanced AI models, additional activities, and customization options. Replika has attracted a dedicated user community of millions of users worldwide who use the app for companionship, mental wellness support, and social skill development. The company has navigated significant content policy changes regarding the nature of relationships users can have with their AI companions.
