Once Books vs Hooray Heroes
A playful family-avatar builder, or your child’s real face in 24 styles.
Reviewed 26 August 2026
Hooray Heroes lets you build a cartoon avatar of your child — and up to five family members or pets — and drop them into a warm, playful printed story. It makes a lovely multi-character gift, but the characters are menu-built avatars in a single house style, not your child’s real face. Once Books builds each character from a photo and keeps that exact likeness on every page, in any of 24 art styles, available as a digital book from $9.99 or a hardcover, with a free preview. Pick Hooray Heroes for a family-cast avatar book; pick Once Books when likeness and art-style choice matter most.
Choose Hooray Heroes if
you want a playful book starring a cartoon cast of the whole family and pets.
Choose Once Books if
you want each character built from a real photo, in your choice of 24 art styles.

- An established brand with print gifting well figured out.
Where Once Books wins

- A digital edition from $9.99 alongside the printed hardcover.
- A free preview of the opening pages before you pay.
Your child’s photos are used only to build that book’s character references — never to train AI. See how it works and the 24 art styles.
The bottom line
For a fun, family-wide cast of cartoon avatars, Hooray Heroes is a strong choice. If you want the book to look like your child specifically — real likeness, your chosen art style, every page — Once Books is the better fit, and still handles siblings, family and pets.
