How to Write and Illustrate Your Book With AI (a Naples Guide)

By Zechariah Myrick · September 22, 2026 · 12 min read

Yes, you can write and illustrate a book with AI, and you can do it in your own voice. AI is best used as an outliner, an editor, and an illustrator that takes direction. The words, the story, and the decisions stay yours. With a plain process and a little patience, a manuscript that has sat in a drawer for years can become a printed book you can hold.

This guide is for people in Naples and Collier County who have a book in them. Maybe it is a children's story you told your grandkids. Maybe it is a memoir, a family cookbook, or a novel you started in 1994. You are comfortable with a phone and email, but the AI tools feel like a wall. I am Zechariah, and I run a one-person AI studio here in Naples. I am independent and not affiliated with OpenAI, Anthropic, xAI, or Google. I will never ask you for a password. Here is how I think about a book project, start to finish.

The man with the drawer and the man with the saw

Picture a man in Naples, call him Walt. He is fictional, but you may know him. Walt has a manuscript in his desk drawer. Two hundred pages, typed in 1998. Every January he takes it out, reads the first chapter, feels good, and puts it back. His neighbor across the canal bought a beautiful new table saw last spring. It has every feature. It is still in the box.

Which of those two is closer to a finished book? Neither, and for the same reason. Walt has the material but no tool. The neighbor has the tool but nothing to cut. AI is the saw. Your drawer is the lumber. This guide is about putting the two in the same room and turning the saw on, carefully, with your hand on the work the whole time.

The line to remember: a tool in a box and a book in a drawer weigh exactly the same.

Do I need to start over, or can I use what I already have?

Use what you have. Nearly everyone who calls me about a book already has something. Handwritten pages. A Word file from an old computer. Voice recordings. A stack of notes. Do not throw any of it out and do not rewrite it yet. Your first job is simply to get it all into one folder on one computer.

• Type or photograph handwritten pages. A phone photo is fine for now. AI can read most clear handwriting and turn it into text you can edit.
• Find every old file and put a copy in one folder named for the book. Do not sort by quality yet.
• Write one paragraph, in your own words, about what the book is and who it is for. This becomes the compass for everything that follows.
• Decide which chunk is the most finished. That chunk is where the AI work begins.

How does AI help me write a book without replacing my voice?

AI is a hammer that gets new features every week. If nobody showed you how to swing it, the features do not help. For writing, the swing is this: you supply the raw material and the judgment, and the AI supplies structure and a second pair of eyes.

• Outlining. Paste in your notes and ask for three possible chapter orders. Pick one. Change it. The outline is a map, not a contract.
• Filling gaps. Ask the AI what a reader might want to know that your draft skips. It will list questions. You answer them in your own words.
• Editing, not rewriting. Ask for a list of unclear sentences and repeated words. Do not ask it to “make this better.” That is how your voice disappears.
• Reading it back. Ask the AI to read a chapter aloud, or use your phone's read-aloud feature. You will hear problems your eyes skip.
• Keeping a style note. Write down five things about how you write. Short sentences. No slang. Warm, not sappy. Give that note to the AI at the start of every session.

A useful rule: if the AI writes a paragraph you would not have written, cut it or rewrite it by hand. Readers can tell. The book should sound like you at the dinner table, only tidier.

Keep the original files untouched. Make a copy before every AI editing session, and name the copies by date. The single most common heartbreak I hear about is a good draft overwritten by a worse one.

Why does my AI character look different in every picture?

This is the number one problem with illustrated books, especially children's books. You describe a little girl with red boots and a yellow raincoat. Page one looks perfect. Page two, her hair is different. Page five, she is a different child entirely.

Here is the picture that makes it click. Imagine you hired a different portrait painter for every page of your book. Each painter works alone in a separate room. Each one gets the same index card: “girl, red boots, yellow raincoat.” None of them ever sees what the others painted. Would you expect twelve matching portraits? Of course not. That is what the AI is doing. It does not remember the picture it made before. Each image starts from scratch, guided only by the words you type.

Now imagine you walk into each room and pin the same finished portrait to the wall before the painter starts. Suddenly the twelve pictures agree. That pinned portrait is called a reference sheet. It is one image, or a small set, showing your character from the front, the side, and in a few poses. You approve it once. Then every new illustration request includes that sheet and the same written description, word for word. It is not perfect, but it turns a coin toss into something you can work with. I wrote a full walkthrough here: why your AI character looks different in every image.

• Write a character card: name, age, hair, clothes, one personality trait. Keep it under 60 words.
• Generate ten candidate images. Pick the one that feels right. That is your reference.
• Ask for a turnaround: front, side, back, and two expressions, all matching the reference.
• Save the sheet and the card in your book folder. Use both for every page.
• Expect to throw away most attempts. Three good pages from twenty tries is normal.

The line to remember: the painter cannot match a picture nobody showed him.

What does print on demand mean in plain words?

Print on demand means a book is printed only when somebody orders it. You do not buy a thousand copies and store them in the garage. You upload your finished files once. When a reader orders, one copy is printed and shipped. This is how most self-published books are made today.

The two services most people use are Amazon KDP and IngramSpark. Amazon's KDP help center describes a Bookshelf where you upload your manuscript and cover, a Print Previewer to check for errors before you publish, and calculators to estimate your printing cost and royalty for paperback and hardcover. IngramSpark's own overview says it offers ebook and print distribution from one platform and connects a book to over 45,000 libraries, retailers, and online stores. IngramSpark also notes you need an ISBN, formatted cover and interior files, an email address, and a payment method. An ISBN is simply the number that identifies your book in bookstore systems.

Which one is right for you depends on where you want the book sold and whether family copies or bookstore copies matter more. That is a conversation, not a rule. Many authors use both. Whichever you pick, order one proof copy before you tell anyone the book is done. Hold it. Read it on the lanai. Mark it with a pen. The proof always finds something the screen hid.

Who owns a book written and illustrated with AI?

You own your words. Your manuscript is yours, whether an AI helped you outline it or not. Images made entirely by AI are a grayer area, and the rules are still moving. Each AI service has its own terms about what you may do with what it makes. I am not a lawyer and this is not legal advice.

What I tell every author is simple. Read the terms of the specific service you use. Keep records of what you made and when. If the book will be sold widely, spend an hour with an attorney who handles publishing. For a family book that lives on a shelf in Naples, most people find this less of a worry.

How long does it really take to finish a book with AI?

Longer than the ads suggest and shorter than doing it alone. Here is what I consider realistic for a person working a few hours a week.

• Gathering and typing up what you have: one to three weeks.
• Outline and first clean draft: four to eight weeks for a memoir; two to four weeks for a short children's book.
• Illustrations with a consistent character: two to six weeks, mostly spent throwing pictures away.
• Layout, cover, and print files: two to four weeks, including a proof copy you hold in your hand and mark up.
• Total: three to six months is a fair expectation. A year is not a failure.

If you have already written most of the book, cut those numbers in half. If you are starting from stories in your head, add a month for recording and transcribing. My guide on preserving your family history or memoir with AI covers that part.

Tricks nobody tells you

These are the small moves that separate people who finish from people who get frustrated and quit. Each one takes a minute to learn.

• Tell it who you are and who it should be. Start every session with a sentence like: “I am a 72-year-old retired teacher writing a children's book for my grandchildren. You are a patient editor who never rewrites my sentences and never uses jargon.” The AI behaves very differently once it knows the room it is in.
• Make it ask before it answers. Type: “Before you do anything, ask me five questions about this book.” The questions it asks will show you the holes in your own plan, and the work that follows is twice as useful.
• The two-versions trick. Ask: “Explain book formatting to me like I am new here. Then give me the version for someone who has done this for forty years.” Read both. The first teaches you. The second shows you what you can safely skip.
• Ask what it is not sure about. After it drafts anything with facts in it, type: “List everything in that answer you are not certain of.” This is the fastest way I know to catch invented details before they reach print.
• Talk instead of type. On a phone, tap the microphone on the keyboard and speak your chapter. Then paste the result into the AI and ask it to remove filler words and keep everything else exactly as spoken. Many of the best memoirs I have seen started as a person talking to a phone on a porch.
• Photograph the handwritten page. Take a clear phone photo of a handwritten page, paste it into ChatGPT, Claude, or Gemini, and type: “Type this out exactly, and mark any word you cannot read with [?].” Then fix the [?] marks yourself. A hundred pages goes faster than you would think.
• Ask it to argue the other side. Before you cut a chapter or change the ending, type: “Make the strongest case for keeping it exactly as it is.” You will either be convinced or you will be sure. Both are better than guessing.
• Save one great conversation as a recipe card. When a session goes well, ask: “Summarize the instructions I gave you today in a short list I can paste at the start of our next session.” Save that list in your book folder. It becomes the first thing you paste every time, and the AI stops forgetting how you like to work. My guide on why AI forgets your project instructions explains why this matters.

Try this in ten minutes

Do not plan. Do this one thing today and end up holding a real result.

• Pick one page you have already written. Just one. Paste it into ChatGPT, Claude, or Gemini.
• Type this first: “I am the author. You are a careful editor. Do not rewrite anything.”
• Then type: “List the three sentences on this page that are hardest to follow, and tell me why in one plain line each. Do not fix them.”
• Read its three picks. Fix each one yourself, in your own words. Two minutes apiece.
• Now type: “Ask me two questions a reader would have after this page that I have not answered.” Answer them out loud to yourself.
• Save the page with today's date in the file name. You now have a page that is better than it was ten minutes ago, and you know exactly how it got that way. That is the whole method, and it scales to two hundred pages.

What I would do first

• This week, gather. Put every note, file, and photo for the book into one folder. Do not edit anything. Just collect.
• Write the compass paragraph. One paragraph: what the book is, who it is for, and how you want a reader to feel when they close it. Tape it above your desk.
• Try one small AI job. Paste one chapter or one story into ChatGPT, Claude, or Gemini and ask only for a list of unclear sentences. Fix them yourself. Notice how that felt. That is the whole method in miniature.

When to call someone

Picture a woman in Naples, call her Dot. Her outboard motor quit in March. She is handy, so she bought the manual and watched the videos. By June she had it apart on the garage floor in labeled coffee cans. By August she had it back together and it still would not start. Her neighbor finally walked her down to a mechanic, who found the problem in twenty minutes. Dot was not foolish. She simply did not know which of the forty parts to look at, and the manual could not tell her that.

Which would you rather spend: five months, or one afternoon and a little pride? Call when you have been at it for a month and the book is not moving. Call when your character has changed faces for the fifth time and you are ready to quit. Call when you have a finished manuscript and the words “interior file” and “bleed” make you want to lie down. Those are the points where an afternoon with a person who has done this saves weeks.

I work by phone, by video, or in person in Naples. We would start with what you have, decide the smallest next step, and I would show you how to do it yourself where that makes sense. If you are not sure whether your project is ready for help, my guide on choosing the right kind of AI project help may settle it. Otherwise, call (239) 544-6990 or send me a note. Bring the story. Leave the passwords at home.
