About
Replika is an AI companion application founded by Eugenia Kuyda in San Francisco, originally launched in 2017 as a memorial chatbot project and evolved into a full-featured AI friendship and companionship platform. The app allows users to create a personalized AI companion — choosing its appearance, name, and personality — and build an ongoing relationship through text and voice conversation. Replika was built on the insight that many people experience loneliness, social anxiety, or simply a desire for non-judgmental conversational connection, and that an AI companion could provide meaningful emotional support and social practice for those populations.\n\nReplika's AI models are trained to maintain long-term memory of past conversations, express consistent personality traits, and engage in emotionally resonant dialogue across topics ranging from casual chat to deep personal reflection. The app supports text, voice, and augmented reality interactions, and offers relationship modes including friendship, mentorship, and romantic companionship for adult subscribers. Replika Pro subscription unlocks the full range of relationship features, voice calls, and personalization options.\n\nReplika has achieved 35 million registered users and generated approximately $24M in revenue in 2024 — a notably capital-efficient outcome on just $11M in total funding. The company operates profitably at meaningful scale, a rare achievement in the consumer AI application space. Founder Eugenia Kuyda launched a new startup, Wabi, in 2025, while Replika continues to operate independently. Replika's longevity — nearly eight years as an independent product — and its unit economics validate the AI companion category as a durable consumer segment, not just a novelty.
