Characters keep their personality, voice, and established facts over long plays, without drifting into generic assistant replies.
Characters remember events, choices, and how relationships in the story have changed, across sessions. A promise made in chapter one still matters in chapter ten.
Several characters can share a scene and react to you and to each other. Question three suspects in one room, or plan the heist with your whole crew.
Describe a character or a whole adventure to the creator in a chat, with no forms to fill in. Keep it private or share it with other players.
