Children’s Book Illustration Prompt Builder — KDP

Random pretty pages are not a picture book. The hero changes face. The outfit changes color. The light changes from noon to night on one spread. Readers feel it immediately.

The AI Children’s Book Illustration Prompt Builder is a Google Sheets tool for 24 and 32 page picture books. Fill 32 dropdowns. Get five outputs: a main illustration prompt, a character consistency brief, a cover brief, a page spread brief and a style guide. Built for Midjourney Niji and Ideogram. Aimed at Amazon KDP.

FAQ

Will the character stay the same?
The builder forces a lock paragraph on every page. Still make a character sheet first and reject pages that drift.

Does it write the story text?
No. It leaves a text-safe area. You add the words in InDesign, Canva or KDP.

Can I make Peppa or Disney style books?
No. Licensed characters are blocked on purpose.

Is this the same as the Character builder?
No. Character is sheets and poses. This one is picture-book pages, spreads and covers.
