How do I give an AI tool my story bible?

Key facts
  • One page beats twenty: the model reads a limited amount per request.
  • Lead with premise, cast, rules and where you are in the story.
  • Name the things it keeps getting wrong — that is what the brief is for.
  • Re-supply it whenever you start a new conversation.
  • Keep the canonical version outside the chat, so it never gets lost.
Direct answer

Write a one-page brief and paste it at the start of each session: premise in two sentences, the five or six characters who matter with a line each, the rules your world cannot break, and where in the story you are working. Detailed lore is counterproductive — it consumes the same budget the model needs for your actual scene.

Chapter i·Why it matters

Most bad AI output is a context problem wearing a quality costume. A model that does not know your protagonist is fifteen will write her as thirty and sound generic doing it. A tight brief fixes more output problems than better prompting does.

Chapter ii·What to include

  • Premise in two sentences, the way you would pitch it aloud.
  • Five or six characters, one line each: want, role, voice.
  • Hard rules — the magic, the technology, the period, the things that cannot happen.
  • Where you are: act, chapter, what just happened, what comes next.
  • A short list of mistakes it keeps making, stated as instructions.

Chapter iii·Example

A mystery writer keeps a nine-line brief pinned in a note. Every new session starts with it. The tool stops resurrecting a character who died in chapter four, and stops setting scenes in a town the book left two hundred pages ago.
