About Character.AI

Character.AI has built one of the most engaged AI communities on the internet by focusing on the social and entertainment dimensions of conversational AI. The platform lets anyone create custom AI characters with defined personalities, backstories, and conversational styles — from recreations of historical figures to entirely original fictional companions. Users can then chat with these characters in immersive, long-form conversations that remember context across sessions. Voice call functionality adds an audio dimension to character interactions. The community library contains millions of user-created characters across every conceivable niche, from language tutoring personas to creative writing partners. Group chats allow multiple AI characters and human users to interact simultaneously. Parental controls address the platform's large teenage user base, while memory features create ongoing relationships that evolve over time. The c.ai+ subscription unlocks faster responses and access to more advanced underlying models.
