How to Write an Ebook With AI

To write an ebook with AI, do the thinking yourself and let the AI do the typing. Decide who the book is for and what it promises, build an outline, draft one chapter at a time with that outline in view, then spend the time you saved adding what only you know, checking facts and editing. Skip those last steps and you get a generic book that readers can spot from the first page.

Done well, AI can take a first draft from weeks to hours. What it can't do is give your book a point of view. This guide walks through the workflow that works, with prompts you can copy, a list of things to check, and the store rules you need to know before you publish.

What AI is good at, and what it isn't

Knowing this up front saves you from the two common mistakes: asking AI to do everything, or being so wary of it that you never get a draft.

The pattern is simple. AI is strong on speed and structure. You are strong on truth, taste and experience. A good ebook needs both. If you're still choosing a tool, we compare the best AI book writers.

Step 1: Start with the reader and the promise

Never open an AI tool and type "write me an ebook about productivity." You will get a book that could have been written for anyone, which means it helps no one.

Start with two short pieces of writing:

• The reader. One sentence that describes a real person. "A first-time manager at a small company who has never run a one-on-one meeting."
• The promise. One sentence on what they can do after reading. "After reading this, they can run a 15-minute weekly one-on-one that their team finds useful."

Everything else in the project hangs off these two sentences. They go into every prompt you write, and they are the test for every chapter. If you want a deeper walk-through of this step, see our guide on how to write an ebook.

Step 2: Gather your own raw material first

The biggest difference between a forgettable AI book and a good one is how much of you goes in at the start. AI writes from what it is given. Give it little, and it fills the gaps with the most average content it can find.

Before you draft, collect:

• Notes, outlines or slides you already have on the topic
• Questions your clients, customers or readers ask again and again
• Two or three real stories, with what happened and what you learned
• Numbers from your own work (results, time saved, price ranges)
• Opinions you hold that others in your field might not
• Links or sources you trust and want the book to rely on

Paste or upload these into your tool along with the prompt. If you coach, consult or teach, a few call transcripts or a recorded workshop are a goldmine. The AI can pull out your own phrases and examples and build around them.

Step 3: Build the outline with the AI, then change it

An outline is the best place to use AI, because it is quick to generate and cheap to fix. Ask for a first version, then edit it hard. Here's a prompt to start from:

Then review it like an editor:

• Does every chapter move the reader toward the promise?
• Is anything repeated under a different name?
• Is a step missing that your reader would get stuck on?
• Would you cut any chapter and lose nothing?
• Is the first chapter useful quickly, or just warm-up?

Merge, cut and reorder until the outline reads like something you would be proud to follow. Fixing an outline takes minutes. Fixing a finished draft takes days. For length guidance by ebook type, see how long an ebook should be.

Step 4: Write a short voice guide

AI defaults to a polite, even, slightly corporate tone. A voice guide pulls it toward yours. It can be six lines long, like this one:

Then paste in 200 to 400 words of your own writing, such as a blog post or an email you are happy with, and add: "Match this style." This one step does more for tone than any other prompt trick.

Step 5: Draft one chapter at a time

Writing the whole book in a single prompt gives you shallow chapters. Writing chapter by chapter, with context, gives you depth and fewer repeats.

For each chapter, give the AI four things: the reader and promise, the full outline, a short summary of what earlier chapters already covered, and the voice guide. Then ask for the draft with a prompt like this:

Three habits help here:

1. Ask for flagged gaps, not inventions. Tell the AI to flag any fact or example it can’t take from your notes. A visible gap is far better than a confident, made-up example.
2. Keep a running summary. After each chapter, ask for a 4-line summary and add it to your context. This is how you stop chapter 7 from re-explaining chapter 2.
3. Draft in order, edit later. Don't polish as you go. Get all the chapters down, then step back.

Some tools do this for you. Koobe, for example, writes each chapter knowing what earlier chapters covered, so you don't have to manage the summaries by hand.

Step 6: Make it yours

This is the step that decides whether the book is worth buying. A first AI draft is competent and flat. Your job is to add what a machine does not have.

For each chapter, ask yourself:

• Where is my story? Add one real moment, with details: who, when, what went wrong, what changed.
• Where are my numbers? Add a result, a range, a time or a cost from your own experience.
• Where do I disagree with the usual advice? Say so, and say why. Opinions are what readers remember.
• What would I cut? Delete the paragraph that restates the point you just made.

Also watch for the habits AI writing tends to fall into. Once you know them, you will see them everywhere.

Reading chapters out loud is a fast test. If you would never say a sentence to a real person, rewrite it.

Step 7: Check every fact

AI can sound sure and be wrong. It can attach a real-looking statistic to a fake study, misstate a law, or invent a quote. You are the publisher, so you carry the responsibility.

Check every one of these against a reliable source before you publish:

• Statistics, percentages and dollar figures
• Names, titles, companies and dates
• Quotes (including whether the person said them at all)
• Laws, rules, fees and platform policies
• Any health, legal, tax or money claim

If a claim is high stakes, such as medical or legal guidance, have a qualified person review it. If you can't find a source for a claim, remove it. Go through every gap the AI flagged and fill or cut each one before export.

Step 8: Edit in passes

Read the whole book quickly for structure, then go chapter by chapter for clarity, then proofread last. Our guide on how to write an ebook covers the three-pass method in detail. With an AI draft, plan to spend more time here than on drafting. That time is what makes the book good.

If you can, give the draft to one or two people from your target audience and ask where they got confused or bored.

Step 9: Design, format and cover

Once the text is solid, you need a cover and the right files. Most ebooks need an EPUB for stores and a PDF for direct sales. Not sure which to use? Read PDF vs EPUB. For cover sizes by store, use the ebook cover size guide. If you plan to sell a paperback too, you will also need a print-ready interior file.

Step 10: Disclose AI use where stores require it

Different stores have different rules, and they are easy to meet if you know them.

• Amazon KDP asks whether your text, images or translations are AI-generated. If an AI tool wrote the content, it counts as AI-generated even if you edited it a lot, and you must say so. If you wrote it yourself and used AI only to edit or brainstorm, that is AI-assisted and doesn't need disclosing.
• Apple Books asks for AI-generated content to be labeled with an "AI Generated by" credit and a note in the description. Unlike KDP, Apple treats an AI-made cover on a book written by a person as AI-assisted, with no disclosure needed.
• Etsy requires a disclosure in the listing when an item is created with AI.

We explain all of this in Can I publish a book written by AI on Amazon?. Rules change, so check each store's current policy before you upload.

How long it takes

Here is a realistic plan for a 15,000-word guide, working alongside other things.

That is two to three weeks instead of two to three months, and most of the time goes into the parts that make the book worth reading. Hiring a writer instead usually takes months and costs thousands: see how much an ebook ghostwriter costs.

Common mistakes

• Prompting before planning. Without a reader and promise, you get filler.
• Writing the whole book in one prompt. Chapters come out shallow and repetitive.
• Publishing the first draft. It will read as generic, and some of it will be wrong.
• Trusting facts you haven't checked. One fake statistic can undo a book's credibility.
• Hiding AI use where disclosure is required. It can get a book removed.
• Making many thin books fast. Readers notice, stores crack down, and Koobe's own terms forbid mass-producing low-quality or copycat books. Make fewer books, and make each one good.

Where Koobe fits

Koobe is built around this exact workflow. You describe your book in a sentence or upload your own notes. Koobe plans the chapters, and you see and edit the outline before any writing starts. You choose a length up front: Short is about 8,000 words over 6 chapters, Standard is about 15,000 words over 8 chapters, and Long is about 30,000 words over 12 chapters. Each chapter is written knowing what the earlier ones covered, so examples don't repeat. Afterwards, you can ask the built-in assistant to shorten a chapter, add a missing one, or tighten a section, and you can edit anything yourself.

Koobe then designs four covers with your title and author name lettered in, checks the spelling on each cover, and exports an EPUB, a digital PDF and a print interior PDF. It doesn't publish for you. You upload the files and answer each store's AI question yourself, which is how it should be, since you're the publisher.

Whatever tool you use, the rule is the same: read every page, check every fact, and add what only you can add.

The short answer, again

• Start with a one-sentence reader and a one-sentence promise.
• Feed the AI your own notes, stories and numbers.
• Build and edit the outline before drafting.
• Draft chapter by chapter, with context, and mark gaps instead of inventing.
• Add your stories, numbers and opinions to every chapter.
• Check every fact, and fill or cut every gap the AI flagged.
• Edit in passes, then design, export and publish.
• Disclose AI use where the store asks.

AI makes the first draft fast. What makes the book good is what you add after.
