You get:
- a sequence of “and then” without causality
- no understanding of what each beat must accomplish
- a sagging middle with no midpoint energy shift
- a climax that arrives without sufficient setup
- no mirror between opening and closing images
But structure is not a formula.
It is a promise to the reader about emotional progression.
- Every beat has a job — do it or cut it
- The midpoint flips the protagonist from reactive to active
- The dark night of the soul must feel earned, not manufactured
- The final image must contradict the opening image
Without structural awareness, stories wander instead of build.
This framework forces AI to think like a screenwriting professor, not a plot generator.
Assume the role of a narrative architect and screenwriting instructor specializing in three-act structure (Save the Cat / Story Grid framework). Your task is to generate a complete structural breakdown for a story idea. Before generating, analyze: - the emotional arc the protagonist must travel - the causal chain between beats (no "and then") - where the energy must rise and fall - what the opening and closing images reveal Then generate: ACT I — SETUP (0-25%) - Ordinary World: what the protagonist is missing - Inciting Incident: what disrupts the status quo - Debate: should they go or stay? - Break into Act II: the choice that can't be undone ACT II — RISING ACTION (25-75%) - Fun and Games: the promise of the premise - Midpoint Twist: stakes rise, protagonist shifts from reactive to active - Bad Guys Close In: everything starts falling apart - Dark Night of the Soul: the lowest point ACT III — RESOLUTION (75-100%) - Break into Act III: the realization - Climax: the final confrontation - Resolution: tying emotional threads - Final Image: mirroring the opening image For each beat, provide: - What must happen emotionally - One specific scene suggestion - Common pitfalls to avoid End with a one-sentence "spine" of the story. INPUTS: Story Logline or Concept: [ONE TO TWO SENTENCES] Protagonist's Flaw (what they must overcome): [INSERT FLAW OR "UNKNOWN"] Genre: [DRAMA / COMEDY / THRILLER / ROMANCE / HORROR / OTHER] Target Length: [SHORT STORY / NOVELLA / NOVEL / SCREENPLAY] RULES: - Every beat must have a clear emotional job - The midpoint must change something fundamental - Dark night must come from character flaw, not external bad luck - Final image must contradict opening image - The spine must be one sentence, not a paragraph
- Run this before writing anything — structure is scaffolding, not prison.
- The midline (25%, 50%, 75%) are the most useful; they prevent wandering.
- If a beat feels forced, ask “what would this character actually do here?”
- The “spine” is your pitch; if it’s weak, the structure won’t save it.
- Use the pitfalls section as a revision checklist after your first draft.
Story Logline or Concept: A retired assassin living quietly as a small-town baker is forced back into the life when her estranged daughter is kidnapped by the crime family she betrayed years ago.
Protagonist’s Flaw: She believes violence is the only solution she’s good at, even when it’s destroying the peaceful life she built.
Genre: Thriller
Target Length: Novel
This framework improves outcomes by forcing:
- emotional requirements for every beat
- causal connection between events
- midpoint as active/passive switch
- dark night as character-generated
- opening/closing image mirroring
Great structure doesn’t constrain creativity — it gives it somewhere to land.
