For publishers and platforms

Multilingual read-along editions of children's books

WonderBoox is a production system for illustrated children's books in nine languages, built by Cambrian Labs BV. It produces our own catalogue, and it can produce editions of yours.

Read-along editions of your picture books

Your text and illustrations, narrated with word-by-word highlighting, as fixed-layout EPUB3 with synchronized narration. Tested in Apple Books, the Kobo apps and on Kobo e-readers.

Translation into nine languages

English, Spanish, French, German, Italian, Dutch, Japanese (with furigana), Korean and Chinese (with pinyin). Native-speaker review for every edition delivered to a partner.

Distribution-ready EPUB files

Standard EPUB3 with accessibility metadata, validated and checked before delivery, ready for your distributor or retailer.

Start from any stage

The production system can start from what you already have: your text, your illustrations, existing translations or recorded narration.

How we work

We start with one title, produced to your acceptance criteria.
Your authors and illustrators stay the creators. We use AI for the conversion work, translations get a native-speaker review, and we are open about which steps use AI and follow each retailer's disclosure rules.
You keep your rights. We produce the editions you ask for, in the languages you choose.

Exploring

Partner titles in the WonderBoox app

We are exploring bringing partner titles into the WonderBoox app for families who read in more than one language. If that interests you, tell us how you usually license titles to reading apps.
