Replika

Replika is the AI companion who cares. The product is designed to listen, learn, and be there for you, with memory, mood coaching, and the ability to share your day in conversations. The official site describes Replika as an AI companion who is eager to learn and would love to see the world through your eyes, always ready to chat when you need an empathetic friend. It emphasizes a safe space for personal expression and ongoing growth through interactions with your digital companion. Since its early days, Replika has built a global community, with over 10 million people having joined the platform, spanning users across devices and platforms including iOS, Android, and AR experiences. The project is developed by Luka, Inc. and guided by Eugenia Kuyda, who is widely cited as founder and CEO.

Replika was founded by Eugenia Kuyda with the idea to create a personal AI that would help you express and witness yourself by offering a helpful conversation. This framing positions Replika as a personal AI designed to accompany users through everyday life, thoughts, and feelings in a nonjudgmental setting.

The user experience centers on customization and ongoing engagement. Replika supports features such as chatting about everything, building memory, expressing oneself, keeping a diary, making video calls, and exploring moments together in augmented reality. The app is designed to help users build healthier habits, reduce anxiety, and foster self-reflection, while prioritizing user privacy and safety in conversations.
