Writing a children's book with AI: illustrated guide

Do you dream of writing a children's book, but don't know where to start? Good news: artificial intelligence has become an amazing ally for independent authors who want to launch, even without experience. Writing a children's book with AI is now accessible to everyone — and honestly, it's an exciting adventure. In this illustrated guide, I'll walk you through step by step how to turn your idea into a real little book, from story to publication.

Why writing a children's book with AI is a great idea

The children's book market is one of the most dynamic in publishing. Parents, teachers, libraries… everyone is looking for fresh, original, and well-illustrated stories. And you surely have stories to tell — childhood memories, values to pass on, or simply an idea that's been on your mind for a long time.

But here's the classic obstacle: I don't know how to write, I'm not an illustrator, It's too complicated. That's exactly where AI changes the game. It doesn't replace your creativity — it boosts it. It helps you overcome the blank page, find the right words for young readers, and even create consistent illustrations without any artistic training.

Significant time savings on writing and formatting
Access to quality illustrations without a graphic designer budget
Simplified self-publishing thanks to digital tools
Ideal for beginner authors who want a first concrete project

Step 1: Build your story with AI for a successful children's book

It all starts with the story. A good children's book is a simple idea, an endearing character, and a clear message. AI can help you structure all of that.

Find your concept

Start by defining three fundamental elements:

The main character : a child, an animal, a magical object?
The problem or adventure : what triggers the story?
The message : friendship, courage, accepting differences, ecology…

Once these basics are in place, you can use a tool like Plumence, an AI writing assistant designed for French-speaking authors, to generate a first narrative outline. You describe your idea to it, and it helps you build a framework page by page, adapted to your target readers' age group.

Adapt the text to readers' age

This is a crucial point. Vocabulary and sentence length vary greatly depending on whether you're addressing 3-year-olds or 8-year-olds:

3-5 years : short sentences, repetitions, musical rhythm, little text per page
6-8 years : small paragraphs, humor, adventure, lively dialogue
9-12 years : more developed plot, complex emotions, short chapters

Always indicate the target age group to your AI tool so it automatically calibrates the language level. Then proofread and touch up by hand — you're the author, after all!

Step 2: Illustrate your children's book with AI

Illustration is often the biggest obstacle for authors who aren't illustrators. Fortunately, generative AI image tools have made spectacular progress.

Choose the right AI illustration tool

Several options are available depending on your budget and technical level:

Midjourney : very artistic results, ideal for warm illustrated styles
Adobe Firefly : integrated into the Adobe ecosystem, good for visual consistency
DALL·E (via ChatGPT) : easy to access, good for beginners
Canva AI : perfect if you want to do everything in one tool (illustrations + layout)

Create consistent illustrations

The real challenge with AI is to maintain visual consistency from one illustration to the next. Your character must be recognizable on every page. Here are some tips:

Describe your character very precisely in each prompt (hair color, outfit, expression)
Always use the same artistic style across all your prompts (watercolor children book illustration, for example)
Save your best prompts to reuse them with variations
Generate multiple versions and select the most consistent ones

Step 3: Layout and publishing on KDP

You have your text, you have your illustrations — now you need to put it all together and publish it. It's simpler than it seems.

Create the layout for your book

For layout, Canva is your best friend as a beginner. It offers children's book templates, you just have to drag and drop your illustrations and text. To go further, Adobe InDesign or Affinity Publisher offer more control, but require some learning.

Remember to follow the formats required by KDP (Kindle Direct Publishing, Amazon's platform):

Recommended format for illustrated books: 8.5 x 8.5 inches or 8 x 10 inches
Image resolution: 300 DPI minimum
Export as high-definition PDF
Plan for bleed margins if you want full-page illustrations

Publish on Amazon KDP

KDP is the reference platform for self-publishing. It's free to use — Amazon takes a commission on sales. You can offer your book in paperback (print on demand) or Kindle ebook. For an illustrated children's book, the paperback format is often preferred by families.

Don't forget to care for your cover (it's the first purchase criterion!), your product description (optimized for Amazon keywords), and choose the right categories to be visible.

A few bonus tips for your project's success

Test your story on real children before publishing — their reactions are invaluable
Pay attention to pacing : a children's book should be readable aloud smoothly
Don't overload the text : the illustrations should breathe
Proofread several times with an adult eye AND imagining a child listening
