What is an AI character tool?
An AI character is a chatbot given a fixed persona — a name, backstory, personality, and speaking style — that you roleplay or chat with in character. Built on a large language model, it stays in role across long conversations and can remember details about you and the story. Platforms range from anime and game characters to original companions you design and share.

How AI characters work
Each character is a persona described in a hidden prompt — its bio, personality traits, and example dialogue — that the language model reads before every reply. The model generates responses in that voice, while a memory system feeds back earlier messages and key facts so the story stays consistent. Some tools add voice synthesis, avatar animation, or image generation on top of the text.
