AI Prompt for Novel Outlines
Plot your novel with confidence: this AI prompt builds a full story outline — three acts, character arcs, subplots, and chapter beats. Try it today.
The prompt
You are a developmental editor who plots page-turning novels. Context: I am writing a [GENRE] novel of about [TARGET_LENGTH] for [AUDIENCE]. Premise: [PREMISE]. Protagonist: [PROTAGONIST] (want: [WANT], need: [NEED], flaw: [FLAW]). Antagonist/force: [ANTAGONIST]. Tone: [TONE]. Task: Build the full outline using three-act structure: Act 1 (setup, inciting incident, debate, break into act 2), Act 2 (fun and games, midpoint reversal, bad guys close in, all is lost, dark night of the soul), Act 3 (finale, final image). For each beat: what happens, whose choice drives it, and how it changes the protagonist. Add: a subplot outline (2-3 beats), the thematic question, and 3 "setpiece" scenes to write first. Suggest chapter groupings. Format: Acts with headed beats, then subplot, theme, setpieces. Detailed but writable. Constraints: Every beat must be driven by character choice, not coincidence. The midpoint must genuinely reverse or deepen the story. The climax must test the flaw against the need. No outline bloat: if a beat doesn't change anything, cut it. Keep subplots to one or two — they must reflect the theme.
Variables to fill in
Replace each [variable] in the prompt with your own details:
[GENRE] [TARGET_LENGTH] [AUDIENCE] [PREMISE] [PROTAGONIST] [WANT] [NEED] [FLAW] [ANTAGONIST] [TONE]
Example input
Example: GENRE = 'romantasy', TARGET_LENGTH = '100,000 words', AUDIENCE = 'adult fantasy readers', PREMISE = 'a mapmaker discovers her maps alter the terrain', PROTAGONIST = 'Ilsa, 28, cautious cartographer', WANT = 'safety and order', NEED = 'to embrace uncertainty', FLAW = 'control', ANTAGONIST = 'the Chartist Guild hunting her', TONE = 'lyrical adventure'.
How to use this prompt
Generate, then interrogate every beat: 'could the protagonist choose otherwise?' If yes, the beat is alive. Write the 3 setpieces first for momentum.
Tips for the best results
- Outline the climax first — everything else aims at it.
- The midpoint is the story's hinge; make it the point of no return.
- Theme is a question, not a message: 'what does safety cost?'
Frequently asked questions
Plotter or pantser — which is better?
Whichever finishes books. But even pantsers benefit from knowing the climax upfront.
How do I avoid a saggy middle?
The midpoint reversal + a ticking clock. Middles sag when nothing irreversible happens.
