Start here for a quick tour of the tools that shape every Character, from Name and Avatar to Greeting, Tags, Description, and Definition. You’ll learn what each field does, why it matters, and how the pieces work together to create a better Character experience.
Welcome to the Creator Guide — the guide to creating, refining, and sharing Characters on Character.ai.
Some Characters get built for the world to find, making it to the homepage of the app with millions of fans. Others live in private, built for one person. Both are created with the same tools.
This guide shows you how the tools work — from the basics of creation to the craft behind Characters that feel compelling, consistent, and unmistakably themselves.
By the end, you'll know how to shape a Character that holds together across hundreds of conversations, refine them so they don't drift, and build a profile that stops someone from scrolling past.
What makes up a Character?
A Character is built from a handful of fields, and each one does something specific:
- Name — the identity. What users search for, what shows up in chat, what sticks.
- Avatar — the face. The first visual impression on discovery pages, profile cards, and conversations.
- Voice — how the Character sounds. The audio feature that gives Characters a voice in calls, stories, and streams.
- Greeting — the opening line. The first thing a user reads when they start a chat. This is where the conversation begins.
- Tags — the signals. Categories that help your Character get found by users browsing for a specific genre, vibe, or trope.
- Tagline — the subtitle. One line under the name that sets tone before anyone starts chatting.
- Description — the story behind your Character. Appears on the profile page to tell users who they're about to talk to and what to expect.
- Definition — the behavioral instructions. Personality, backstory, speech patterns, quirks, and rules — everything that shapes how a Character thinks and responds. Can be public or hidden, your choice.
