The fastest way to break the spell of a picture book is a hero whose face changes from page to page. Consistency is the single hardest thing for AI image tools, and it's where BookBudKids focuses.
One character, defined once
When you create a character, we generate a single canonical portrait and reuse it as a visual reference on every illustration. The same eyes, hair, and proportions carry through the whole book.
A cast line-up for relative height
In multi-character stories, the model can drift on who's taller. So when a book has two or more characters we build a size-comparison sheet — the whole cast standing together at correct relative heights — and feed it into every page. A grown-up stays a grown-up; a toddler stays toddler-sized.
Refine any page
If a page still isn't right, redraw it with a specific instruction. The existing illustration and your characters are used as references, so your edit lands without redrawing the whole book.
