The bedtime story only you could tell in print.
Describe one idea. CustomStory writes the story, illustrates every page with characters that stay consistent, and hands you print-ready PDFs for Amazon KDP.
Why CustomStory
Everything a finished book needs, in one place
Most tools stop at a paragraph or a single image. CustomStory takes you all the way to a file you can actually publish.
Write with AI
Turn a single sentence into a complete, age-tuned 24-page story with a satisfying arc, not generic filler.
Characters that stay consistent
Your hero keeps the same face, outfit, and colors on every single page. No more uncanny redraws.
Print-ready for Amazon KDP
Export interior + cover PDFs at the exact trim size, bleed, and spine width KDP expects. Upload and publish.
Pick your art style
Watercolor, cut-paper, storybook gouache and more, applied uniformly across the whole book.
A real editor, not a black box
Nudge text, swap fonts, drag layers, and regenerate any single illustration until it’s exactly right.
Minutes, not months
Watch every spread paint in real time. A finished, printable book in an afternoon instead of a year.
How it works
From a sentence to a printed book in four steps
- 1
Describe your idea
One sentence is enough. Pick an age range, tone, trim size, and art style.

Review the plan
CustomStory drafts the full story and a cast of characters. Tweak any page before a single image is drawn.
- 3
Illustrate every page
Approve and watch consistent, full-bleed artwork render spread by spread, in real time.
- 4
Download & publish
Fine-tune in the editor, then export KDP-ready interior and cover PDFs. Your book is done.
Loved by parents, teachers, and illustrators
“I’ve tried to self-publish a kids’ book for three years. With CustomStory I had a print-ready PDF on KDP the same evening, and my daughter is the main character.”
“The character consistency is the real magic. The fox looks like the same fox on page 2 and page 22. That alone is worth it.”
“I make a personalized book for each student’s birthday now. The classroom goes wild. It costs me minutes.”

FAQ
Questions, answered
Do I own the books I create?
Yes. The story and illustrations you generate are yours to publish and sell, including on Amazon KDP and other print-on-demand platforms.
Are the files really ready for Amazon KDP?
CustomStory exports interior and cover PDFs at the exact trim size, bleed, and spine width KDP requires, so you can upload them directly without a designer.
How does character consistency work?
When you approve your plan, CustomStory locks in a visual “bible” for each character and reuses it on every spread, so your hero looks the same from cover to last page.
What if I don’t like an illustration?
Regenerate any single spread or the cover as many times as you like, and fine-tune text, fonts, and layout in the built-in editor.
Do I need any design or writing skills?
No. If you can describe an idea in a sentence, you can make a finished, beautiful book. The editor is there when you want control, not as a requirement.
Your story is one sentence away from being a real book.
