## Definition

A persona is the identity the user brings into an AI character chat, such as a name, role, traits, appearance, or relationship to the character.

## Quick Answer

A persona defines who the user is inside the scene, while the character card defines the AI character. Separating them makes it easier to reuse one user identity across many characters.

## Plain Language

If the character card answers 'who is the AI?', the persona answers 'who am I in this story?'

## Why It Matters

Persona support improves continuity, reduces repeated setup, and helps users switch between story roles without rewriting every character card.

## OnlyKin Angle

OnlyKin uses personas as reusable roleplay context that can support many different character chats.
