30 AI Prompts for Authors: Writing, Editing and Publishing Books

Every author I know has a complicated relationship with AI. Some treat it like a magic vending machine: insert one vague prompt, collect a bestseller. Others refuse to touch it, worried it will flatten their voice into beige, generic prose. The truth sits somewhere between those two anxieties — and it’s much more practical than either one.

AI is not a ghostwriter. It cannot live your life, notice the way your grandmother folded her hands when she was worried, or decide what your novel is about in the way that makes readers cry. What it can do, remarkably well, is act as the most patient writing assistant you’ve ever had: one that brainstorms at 3 a.m., builds timelines for your 40-chapter saga, plays devil’s advocate with your argument, and line-edits your dialogue without ever sighing.

The trick is in how you ask. Vague prompts get vague answers. Detailed prompts — with clear roles, constraints, and your own material pasted in — get genuinely useful help. That’s what this pack is for: 30 copy-paste AI prompts for authors, organised by the real stages of a book project, from the first flicker of an idea to the launch-day marketing plan.

Each prompt includes bracketed placeholders like [genre] or [paste your draft] — replace them with your own specifics before you send. They work in any modern chatbot (ChatGPT, Claude, Gemini, Copilot, or your tool of choice). And if you’re planning a shorter project rather than a full-length book, our guide on how to write an ebook with AI, step by step walks through the whole process in more detail.

One honest note before we begin: treat every AI output as a first draft, never a final one. Your voice, your judgment, and your life experience are what make the book yours. The prompts below are scaffolding — you still build the house.

Ideas and Inspiration (Prompts 1-6)

1. “You are a brainstorming partner for a novelist. I want to write a [genre] novel about [rough theme or situation]. Generate 10 distinct premise ideas, each in two sentences. For each one, include: the central conflict, the emotional wound of the protagonist, and one unusual twist. Avoid clichés like amnesia, chosen-one prophecies, and secret twins. Make premises 3, 6 and 9 deliberately strange.”

2. “Act as a bookshop owner who has read everything in [genre]. Based on this premise: [your premise], suggest 5 comparable bestselling titles and explain in one sentence each what my idea could learn from — and deliberately do differently from — each of them.”

3. “I am writing a [non-fiction topic] book for [target reader]. Give me 20 possible book titles and subtitles that would stop that reader scrolling. Half should be bold and promise-driven, half should be quiet and authority-driven. Mark your top 3 and say why they work.”

4. “You are a character coach. Interview me about my protagonist one question at a time, asking 10 questions total. Start with easy surface questions (name, age, job) and go progressively deeper into fears, contradictions, and secrets. Do not move to the next question until I answer. After question 10, summarise the character in a 150-word profile and flag two weaknesses in the characterisation.”

5. “Generate 15 ‘what if’ story sparks for a [genre] novel set in [setting]. Each should be a single provocative question. Mix grounded, emotional scenarios with speculative ones. Number them. For the three strongest, add a follow-up line: ‘The story really begins when…'”

6. “Act as a sceptical non-fiction reader. I want to write a book arguing that [your thesis]. Attack the thesis: list 10 objections a smart reader would raise, ordered from weakest to strongest, and suggest what evidence each objection would need. Be unsparing — I need to know where my argument dies before I write 60,000 words.”

Outlining and Structure (Prompts 7-12)

7. “You are a developmental editor specialising in [genre]. Turn this premise into a 24-chapter outline: [paste your premise and key characters]. For each chapter give: a one-line scene goal, the conflict, and what changes for the protagonist. Mark the inciting incident, midpoint reversal, and climax clearly. Keep the pacing tight — no chapter should exist just to move furniture.”

8. “I have written a rough outline for my novel: [paste outline]. Analyse it for structure using three-act pacing. Identify: scenes that repeat the same emotional beat, chapters where nothing stakes-raising happens, and the weakest transition between acts. Suggest a concrete fix for each problem you find. Be direct, not encouraging.”

9. “Convert my memoir concept into a chapter structure: [paste your life events or themes, roughly chronological]. Propose 12 chapters that follow an emotional arc, not a calendar. Each chapter needs a working title, the core scene, and the universal question it answers for the reader. Cut anything that serves nostalgia but not the story.”

10. “Act as a story-structure analyst. I will describe my plot point by point, and you will map each one onto the hero’s journey stages. Point out which stages are missing, which are overloaded, and whether the ‘ordeal’ is genuinely the hardest thing my protagonist could face. Here is my plot: [paste plot summary].”

11. “Design a subplot architecture for my novel. Main plot: [one sentence]. Create 2 subplots that (a) echo the main theme in a different key, (b) give the secondary characters their own arcs, and (c) intersect with the main plot at exactly three points each. Show me where those intersections happen on a chapter-by-chapter timeline.”

12. “You are a non-fiction architect. My book topic is [topic] and my reader is [reader description]. Build a table of contents: 10 chapters in the order the reader should learn them. For each chapter: the promise (what the reader can do after reading it), the biggest misconception it must destroy, and one exercise or case study to include. End with an appendix list of checklists I should write.”

Drafting Chapters (Prompts 13-18)

13. “You are my co-drafter. Write the opening 400 words of a [genre] novel scene: [describe setting, characters present, what must happen]. Style rules: sensory detail over adjectives, no dialogue tags beyond ‘said’, end the scene on an unresolved beat. I will rewrite everything in my own voice afterward — your job is to break the blank page.”

14. “Continue this scene in my voice. Study the rhythm, sentence length, and diction of the sample below, then write the next 500 words so a reader cannot tell where I stopped and you started. Do not introduce new characters or resolve the tension. Sample: [paste 300 words of your writing].”

15. “Write a difficult conversation between [character A] and [character B] where A wants [goal] and B wants [opposing goal], but neither says what they truly want directly. Use subtext: interruptions, topic changes, and one physical detail per exchange that betrays the real feeling. 600 words. No melodrama.”

16. “I am stuck on this chapter. Here is where I am: [paste last 200 words and a one-line summary of what should happen next]. Give me 3 different ways the next scene could unfold — a bold choice, a quiet choice, and a choice that raises the stakes. For each, write the first 3 sentences so I can feel which one fits.”

17. “Draft a non-fiction chapter section: [chapter topic] for [reader]. Structure: open with a concrete story or surprising statistic, explain the concept in plain language, give one numbered how-to sequence, and close with a single memorable sentence the reader could quote. 700 words. Conversational but not chatty. No bullet-point soup.”

18. “Act as a ‘show, don’t tell’ coach. I will paste a paragraph, and you will rewrite it twice: version one doubles the sensory detail, version two achieves the same effect in half the words. Then explain in two sentences what each version teaches me about my own writing habit. Here is my paragraph: [paste paragraph].”

Editing and Revising (Prompts 19-24)

19. “You are a brutal copyeditor. Proofread this chapter for grammar, punctuation, and word choice. List every issue with the original phrase, your correction, and a one-line reason: [paste chapter]. Do not praise anything. Do not rewrite for style — only fix what is objectively wrong. Flag any sentence you had to read twice.”

20. “Act as a developmental editor on my first draft. Read this chapter and answer: (1) What does the protagonist want in this scene, and is it clear by page 2? (2) What is the single weakest paragraph and why? (3) Where did your attention drift? (4) If I had to cut 20% of these words, which 20%? Be specific — quote the lines. Chapter: [paste chapter].”

21. “Check my manuscript excerpt for consistency. Characters: [list names with key traits]. Flag: any character acting against their established traits, timeline contradictions, repeated words or phrases within 500 words, and anachronisms for a story set in [time period]. Excerpt: [paste text].”

22. “You are a dialogue specialist. Read this conversation and mark every line that sounds like the author talking instead of the character. For each flagged line, suggest how this specific character — [character description] — would actually say it. Keep their vocabulary, education, and mood consistent. Dialogue: [paste dialogue].”

23. “Punch up this non-fiction draft. It is accurate but dull: [paste section]. Rewrite it keeping every fact intact but: vary sentence length, replace abstractions with concrete images, cut 15% of the words, and add one vivid analogy per 200 words. Show me a before/after of the three most improved sentences and explain each change.”

24. “Do a final pre-publication sweep of this chapter: [paste chapter]. Check for: filter words (felt, saw, noticed, realised), passive constructions that weaken action, clichés, and repeated sentence openings. Return a clean revised version with changes marked in bold, plus a 5-line summary of my most frequent bad habits so I can watch for them in the next chapter.”

Publishing and Marketing (Prompts 25-30)

25. “You are a book marketing strategist. My book: [title, genre, one-line hook, target reader]. Build a 90-day launch plan in three phases (pre-launch, launch week, post-launch), with 3 concrete actions per phase that cost little or no money. Include what to post, where, and the one metric that tells me each phase worked.”

26. “Write 10 Amazon book description options for my [genre] novel. Book details: [paste blurb facts, hook, stakes]. Each description must be under 150 words, open with a hook line, and end with a question or dare. Vary the tone: 3 thriller-paced, 3 literary, 2 funny, 2 mysterious. Mark your recommended pick.”

27. “Act as a literary agent writing my query letter. Book: [title, genre, word count]. Draft a 300-word query: personalised opening line, the hook paragraph, a 150-word synopsis that ends on the central dilemma (not the ending), and a bio paragraph for [my credentials]. Then write the 5 most likely rejection reasons and how I would fix each.”

28. “Create a 30-day social media content calendar to build my author platform before launch. My book is [genre/topic] and my audience hangs out on [platforms]. Give me one post idea per day — mix behind-the-scenes, useful tips, personal stories, and book teasers in a 3:2:3:2 ratio. Write 5 of the posts out fully in my voice: [describe your voice or paste a sample].”

29. “You are a pricing and positioning consultant for indie authors. My book: [non-fiction topic or genre, length, comparable titles]. Recommend: ebook and paperback price points for the UK and EU markets, whether to launch at a discount, 3 categories to target on Amazon, and 7 backend keywords. Explain the reasoning for each choice in one line.”

30. “Draft my author newsletter welcome sequence: 4 emails for new subscribers. Email 1: deliver the freebie ([describe freebie]) and set expectations. Email 2: my story and why I wrote this book. Email 3: the single most useful idea from the book, free. Email 4: the soft pitch with social proof ([paste a review or testimonial]). Each under 250 words, warm tone, one call to action each. Subject lines included.”

A Short, Honest Word on Originality and AI Disclosure

Let’s be straight about something: an AI can help you write a book, but it cannot be the author. Readers connect with a human mind behind the words — your obsessions, your blind spots, your particular way of noticing things. If you paste AI output into your manuscript untouched, the prose will usually read competent and forgettable. The writers getting real value from these prompts are the ones who argue with the output, steal the good 10%, and rewrite the rest until it sounds like them.

A practical note on disclosure: some publishing platforms, competitions, and retailers now ask whether AI tools were used in creating a book. Answer honestly when asked — it costs you nothing and protects you later. Expectations around copyright and attribution for AI-assisted work also differ across Europe, and the rules are still settling, so if your book is a commercial project, it’s worth checking the current guidance in your country rather than assuming. None of this is legal advice — just the common-sense version: be transparent, keep your own creative fingerprints all over the work, and don’t outsource the parts only you can do.

The Bottom Line: How to Actually Use These Prompts

Thirty prompts are useless if they sit in a bookmark folder. Here’s how to make them work:

• Start with the stage you’re actually at. Stuck on chapter 9? Skip the idea prompts and go straight to the drafting and editing sections. These are tools, not a syllabus.
• Paste your real material. The prompts with [paste chapter] and [paste your draft] placeholders are the most powerful ones — AI is dramatically better when it has your actual text to work with instead of abstract questions.
• Iterate, don’t accept. The first answer is a starting point. Follow up with “make it darker,” “cut the adjectives,” or “now argue the opposite” — the second and third generations are usually where the gold is.
• Keep one document of what worked. When a prompt gives you something brilliant, save the exact wording you used. Within a month you’ll have your own personal prompt pack tuned to your voice.
• Protect your voice on purpose. After any AI-assisted session, read the result aloud. If a sentence doesn’t sound like something you’d say, rewrite it. Your ear is the final editor.

Writing a book has always been lonely, slow work — and that’s exactly why it’s worth doing. AI doesn’t change that; it just means you don’t have to be lonely and stuck at the same time. If you’re also creating shorter content alongside your book, our pack of AI prompts for content creators covers the day-to-day side of an author’s platform too. Now close this tab, open your manuscript, and get to work — your future readers are waiting.
