AI Prompts for Writing a Novel: 40 Copy-and-Paste Prompts for Plot, Characters and Scenes (2026 Guide)

How do you get good results from AI prompts when writing a novel?

A good prompt has four parts: a role, your context, a specific task and a format for the answer. For example: “You are a developmental editor who knows [genre]. My novel is [one-line premise]. Do [task]. Give me [number] options as a short list.” The context is what matters most. The more specific you are about genre, tone, point of view and reader expectations, the less generic the output.

Ask for options, not answers. Requesting five or ten variations gives you something to react to, and your reaction is where your taste comes in. Then follow up. Replies such as “make option 3 darker” or “this is too predictable, give me something less obvious” usually beat starting again from scratch.

Paste a short story summary at the top of each new chat so the AI remembers your book. Tools differ in how much they retain between sessions, so do not assume it remembers anything you said earlier. For the bigger picture of drafting with AI, see our guide on how to write a book with AI.

Which AI prompts help with premise and plot?

Use these when you are choosing an idea or shaping the story spine. Run each one several times and keep only what excites you.

• Prompt 1, premise options: “Give me 10 novel premises in [genre] with a [tone] feel. Each should be two sentences and include a protagonist, a want and an obstacle. Avoid the most common tropes of the genre.”
• Prompt 2, what-if engine: “Take this idea: [idea]. Ask me 10 ‘what if’ questions that would make it more original or more emotionally risky. Do not answer them yourself.”
• Prompt 3, logline: “Write five one-sentence loglines for this story: [summary]. Each must name the protagonist, the goal, the antagonist force and the stakes.”
• Prompt 4, genre check: “Here is my premise: [premise]. List the reader expectations of [genre] that my story must meet, and two ways I could twist them without breaking the promise.”
• Prompt 5, stakes ladder: “My protagonist wants [goal]. Suggest five escalating levels of stakes, from personal to public, and tell me which one suits a [word count] novel.”
• Prompt 6, three-act skeleton: “Using my premise [premise], outline a three-act structure with the inciting incident, first plot point, midpoint, low point, climax and resolution. Keep each beat to two sentences.”
• Prompt 7, midpoint ideas: “My story is [summary]. Give me eight possible midpoint reversals that change what the protagonist believes or wants, ranked from safest to boldest.”
• Prompt 8, plot hole hunter: “Read this outline and list every point where the logic, timeline or character motivation does not hold up. Be blunt. Outline: [paste].”
• Prompt 9, subplot suggestions: “Suggest five subplots for [summary] that reinforce the main theme of [theme] and intersect with the main plot at the climax.”
• Prompt 10, twist stress test: “I plan this twist: [twist]. Tell me how a reader might guess it early, what clues I must plant, and one way to make it feel inevitable rather than random.”

If you need a full structure method before prompting, our guide to outlining a novel covers proven approaches you can combine with these.

Which AI prompts help you build characters?

Characters are where generic AI output shows most, because it defaults to stereotypes. These prompts push for specificity and contradiction.

• Prompt 11, protagonist profile: “Build a protagonist for a [genre] novel. Give me their job, a habit that annoys others, a secret, a want and a deeper need that conflicts with the want. Avoid cliché occupations.”
• Prompt 12, flaw with consequences: “My protagonist is [description]. Suggest three flaws that would cause real trouble in the plot, and for each give one scene where the flaw makes things worse.”
• Prompt 13, backstory wound: “Write a short backstory for [character] that explains their biggest fear. Keep it under 200 words and include one specific memory with a sensory detail.”
• Prompt 14, character arc: “Map a change arc for [character] across my three acts. For each act, state what they believe, what challenges that belief and how their behaviour shifts.”
• Prompt 15, villain with logic: “Create an antagonist for [summary] who believes they are right. Explain their goal, their method, the line they will not cross and the moment the reader might sympathise.”
• Prompt 16, supporting cast: “Suggest four supporting characters for [summary]. Each should push the protagonist in a different direction and have a distinct way of speaking.”
• Prompt 17, voice sample: “Write 150 words of [character] describing a rainy bus ride, in a voice that reveals their background and mood without stating either.”
• Prompt 18, relationship tension: “Describe the relationship between [character A] and [character B]. List five sources of conflict and three moments of unexpected tenderness.”
• Prompt 19, interview: “Act as [character] and answer my questions in their voice. I will ask about their past, fears and secrets. Stay in character and refuse to answer anything they would hide.”
• Prompt 20, names: “Suggest 15 names for a [age, background, setting] character. Avoid names that are currently overused in [genre] and explain the feel of the top three.”

For quick inspiration alongside these, CruxOne’s free Character Name Generator and Character Flaw Generator are handy starting points.

Which AI prompts help with setting and worldbuilding?

Setting should shape the story, not decorate it. These prompts ask the AI to connect place to conflict, which is where most worldbuilding either earns its place or becomes padding.

• Prompt 21, setting that pressures: “Describe a setting for [genre] that constantly creates problems for the protagonist. Include three physical features that could each trigger a plot event.”
• Prompt 22, sensory palette: “List ten specific sensory details (sound, smell, texture, light) for [location] at [time of day]. Avoid clichés like ‘the smell of coffee’.”
• Prompt 23, rules of the world: “My story includes [magic, technology or institution]. Propose five rules and, for each, one cost or limitation that creates drama.”
• Prompt 24, culture and customs: “Invent three everyday customs for the people of [place] and show how each would complicate a secret meeting.”
• Prompt 25, historical accuracy check: “I am writing a scene set in [time and place]. List details I should verify, such as language, technology, clothing and social rules. I will check them against reliable sources.”
• Prompt 26, worldbuilding diet: “Here is my world summary: [paste]. Tell me which details a reader needs in chapter one and which can wait until later, so I avoid an info dump.”

Treat anything factual the AI produces as unverified. For real places, periods or professions, always check with trustworthy sources.

Which AI prompts help you write scenes and dialogue?

Scene prompts work best when you supply the goal, conflict and outcome. Use the AI to plan or to produce a rough version you then rewrite in your own voice.

• Prompt 27, scene blueprint: “Plan a scene in which [character] wants [goal] but [obstacle] stops them. Give me the opening image, the turning point, the outcome and the emotional shift, in five bullet points.”
• Prompt 28, opening hook: “Give me eight possible first lines for a [genre] novel about [premise]. Each should raise a question and use a concrete detail, not a weather report.”
• Prompt 29, first chapter check: “Here is my chapter one: [paste]. Tell me where a reader might lose interest, what the hook is, and whether the protagonist’s want is clear by the end.”
• Prompt 30, subtext dialogue: “Write a conversation between [A] and [B] where they argue about [surface topic] but are really fighting about [real issue]. Nobody states the real issue.”
• Prompt 31, show don’t tell: “Rewrite this paragraph so the emotion is shown through action and body language, not named: [paste]. Give two versions with different intensity.”
• Prompt 32, cliffhanger endings: “Suggest six ways to end this chapter on tension without a cheap trick: [chapter summary].”
• Prompt 33, pacing diagnosis: “Look at this list of scene summaries. Mark which ones are slow, which repeat information and which could be merged: [paste].”
• Prompt 34, action scene: “Choreograph a fight or chase in [location] in clear, beat-by-beat steps so I can write it with confusion-free geography. Include two moments of failure for the protagonist.”
• Prompt 35, emotional beat: “Describe how [character] reacts in the first minute after [event], in a way that is surprising yet believable for their personality.”

Our guides on dialogue and first chapters go deeper on the craft behind these prompts.

Which AI prompts help with revising your draft?

Revision is where AI can act as a tireless first reader. Paste in manageable chunks, because long texts can be truncated or handled poorly depending on the tool.

• Prompt 36, consistency check: “Here are my character notes and a chapter. List anything in the chapter that contradicts the notes, including eye colour, timeline and knowledge a character should not have: [paste].”
• Prompt 37, repetition and filler: “Highlight repeated words, filter words (such as ‘felt’, ‘saw’, ‘seemed’) and sentences that add nothing in this passage. Do not rewrite it, just list them: [paste].”
• Prompt 38, reader feedback: “Act as a [genre] reader who dislikes slow openings. Read this scene and tell me where you would skim or stop reading, and why: [paste].”
• Prompt 39, theme audit: “My intended theme is [theme]. Based on this summary, tell me which scenes support it, which contradict it and where it could be sharper: [paste].”
• Prompt 40, blurb draft: “Using this summary, write three back-cover blurbs of about 150 words with a hook, setup, stakes and a closing question: [summary].”

AI feedback is a supplement, not a verdict. For deeper issues, beta readers and a human editor still catch what a model cannot, so see our guides on beta readers and hiring an editor.

What are the limits and risks of using AI prompts for a novel?

AI tends toward the average. Without careful direction it favours familiar plots, tidy emotions and repeated phrasings. Counter this by asking for unusual options, rejecting the first answer and always rewriting in your own voice. If a passage could appear in any book, it probably should not appear in yours.

There are practical and legal questions too. Retailers such as Amazon KDP ask you to disclose AI-generated content when you publish, and policies and copyright treatment of AI output differ by country and can change. Check the current rules for each store you sell on, and read our guide on copyrighting a book. Also check the terms of the AI tool you use, particularly on how it treats your uploaded text.

A browser-based platform such as CruxOne, an AI publishing platform for indie authors, includes AI writing and editing tools, but the principle is the same whichever tool you choose: you decide the story, the AI helps with the work around it. Use prompts to speed up planning and revision, then do the part readers actually fall in love with, the voice, yourself.

Frequently asked questions

What is the best AI prompt for writing a novel?

There is no single best prompt. The best ones state your genre, characters, stakes and the exact task, and ask for several options rather than one answer.

Can AI write a whole novel for me?

It can produce text, but long fiction usually comes out generic and inconsistent without heavy direction. Most authors get better results using AI for brainstorming, outlining and revision while writing the prose themselves.

Do I have to disclose AI use when publishing on KDP?

Amazon KDP asks authors to say whether content is AI-generated when publishing. Rules can change, so check the current KDP guidance before you publish.

How do I stop AI writing from sounding generic?

Give specific context, ask for unusual options, set a clear voice sample and rewrite the output yourself. Reject the first answer and push for something less predictable.

Are these prompts free to use?

Yes, copy them as you like. They work in most AI chat tools, though results vary by tool and by how much detail you add.
