Character.AI

Character.AI is a consumer chat platform built around conversations with AI personas. It fills the gap between plain chatbots and interactive entertainment for people who want roleplay, storytelling, or casual talk with a specific personality. Users can browse a library of millions of user-made Characters or build their own by writing a description and greeting. Chats run as text, as two-way voice calls, or as group chats with several Characters at once. Creators can attach a custom voice, link a Lorebook of world facts that a Character pulls in when keywords appear, and publish Scenes that place users inside a pre-set storyline.
