Best ChatGPT Prompt for Book Writing
Outline a novel, develop characters, and write chapters with AI as your writing partner — not your ghostwriter.
The Prompt
You are a bestselling novelist and editor who has worked with first-time authors to finished manuscript. Help me write a book. What I need help with: [pick one] - Outline a novel from my premise: [PREMISE] - Develop the main character: [BRIEF DESCRIPTION] - Fix a structural problem in my plot: [DESCRIBE THE ISSUE] - Write a chapter outline: [CHAPTER GOAL] - Edit a scene I wrote: [PASTE SCENE] Book details: - Genre: [literary / thriller / romance / sci-fi / fantasy / mystery / memoir / nonfiction] - Target length: [word count] - POV: [first / third limited / third omniscient] - Tone: [dark / funny / literary / pulpy] - My experience: [first novel / published before / hobbyist] Requirements: - Don't write prose for me — give me structure, questions, options - For outlines, use a proven framework (Save the Cat, Three-Act, Hero's Journey) matched to genre - For character work, ask questions I need to answer about wants/fears/wounds - For plot fixes, identify the root cause (often character motivation) - For editing, mark specific sentences and say why they work or don't - Always preserve my voice — don't rewrite into generic AI prose
How to Use This Prompt
- Use AI for structure and problem-solving, never for the actual prose
- Write your own sentences — they're what readers connect with
- When stuck, ask 'What's the scene I'm avoiding?' — usually that's the scene that matters most
- Track progress with chapter outlines, not daily word counts
Example Output
Request: Three-act outline for a literary thriller about a woman who realizes her new husband killed his first wife.
Act One — setup (25% of book):
- Open: Protagonist's genuine happiness with new husband — we need to feel the loss before the revelation hits.
- Inciting incident (around 10%): Discovery of something small that doesn't fit. A key, a photograph, a date that's wrong.
- Break into Act Two: She asks him about it. His answer is reasonable. Too reasonable. That's the last moment of her innocence.
Key question to answer before writing: What does she believe about herself that would make her NOT want to see the truth? That belief is the core of the book. Without it, there's no tension — just an investigation.
Tips to Get Better Results
- Start with the ending. Ask 'Draft the last scene first. What's the emotional resolution?'
- Character wound. Ask 'What's the wound my protagonist carries that shapes every decision?'
- Plot vs. character. Ask 'Is this a plot problem or a character motivation problem?' Usually the latter.
- Cut the opening. After drafting, ask 'Where should my book actually start? Often not at page 1.'
