AI Character Personality — How Traits Shape Every Reply
AI character personality is the trait system underneath every response: tone, boundaries, interests, and speech style that get set during character creation and then consistently drive how a character replies, from first message to hundredth. This page is about the mechanics of personality itself, not the setup flow. Stronger, more specific traits produce more distinctive replies. A character defined only as 'friendly' behaves more generically than one with specific interests, quirks, and communication style.
