Direct answer
What is Replika?
Replika is an AI companion application that provides personalized conversations, persistent memory, voice calls, and customizable 3D avatars across iOS, Android, and web platforms.
Replika was created by Luka, Inc. to serve as a personal conversational companion. Rather than functioning as a transactional productivity tool, it focuses on emotional intelligence, continuous conversation, and relationship building. The companion adapts to individual users over time, tracking personal routines, shared relationships, ongoing projects, and personal interests to maintain context across sessions. Interactions take place through chat messages, phone calls, selfies, and visual reactions. Users can customize the appearance of their companion to fit their preferences. According to vendor documentation, conversation history is preserved to keep discussions relevant over months and years, supporting daily emotional check-ins, casual socialization, and reflection. Replika operates across iOS, Android, and web browsers. Real-time augmented reality experiences and selfie filters utilize on-device frameworks, such as Apple ARKit and TrueDepth cameras, to track head and facial movements without transmitting or persistently storing biometric data. Conversation generation relies on third-party language models protected by contractual data minimization and non-training commitments.
Unlike task-oriented productivity chatbots, Replika is built from the ground up for emotional presence, tracking personal routines and relationships over time to act as a persistent companion rather than an informational search engine.
