Character AI

Character AI is a platform that lets users create and chat with AI-generated characters, founded in 2022 by former Google researchers Noam Shazeer and Daniel De Freitas. Users can design characters with custom personalities, backgrounds, and behavioral traits, then engage in open-ended conversations. The platform hosts millions of user-created characters ranging from historical figures to fictional personas to original creations. Character AI accomplishes this through proprietary large language model technology that maintains character consistency across long conversations. The service is free with optional premium features, and has been particularly popular among younger users for creative roleplay and storytelling.
