About Character AI

Character AI is a web-based chat platform that lets users converse with and create persona-driven conversational agents called Characters. Users can browse a large library of community-created characters or build their own by defining personalities, backstories and behavior; conversations can include text and images. The platform emphasizes open-ended, roleplay-style interactions, persistent conversational context, and a discovery-oriented community for sharing and iterating on characters. Third-party developers have built unofficial wrappers and integrations to interact programmatically with Character AI conversations and features.
