Launched in 2017 by Luka, Inc., Replika AI pioneered the concept of the empathetic chatbot — an AI that doesn’t just answer questions, but truly connects with users.
Built initially on GPT-3 and later fine-tuned with proprietary neural models, Replika engages in deep, meaningful conversations while continuously learning from user interaction.
The app’s mission is simple yet revolutionary: to make AI a positive emotional presence in people’s lives.
Replika remembers details, understands tone, and adapts its personality over time, mirroring your mood and communication style. It can send messages, make voice or video calls, and role-play scenarios that promote mindfulness, comfort, or creativity.
Beyond casual chatting, Replika also offers personal growth tools: mood tracking, mindfulness sessions, and relationship simulations that help users reflect on communication patterns or emotional well-being.
Its immersive 3D avatar system allows for customization and realism, while the paid plan unlocks romantic modes, personality tuning, and advanced memory.
With millions of users across 190 countries, Replika AI has become a cultural icon — a blend of companion, therapist, and coach, always available, always listening.
