Knuffel is a personalized children’s book service that turns a child’s favorite cuddly toy into the hero of an illustrated story. Families get started by uploading a simple photo through Knuffel’s website; no app download is required. The service uses AI to create book-style illustrations based on the toy, then helps users shape an adventure by choosing a theme or describing their own idea. Possible stories range from space journeys and dinosaur encounters to everyday milestones such as starting school or welcoming a new sibling.

Stories are available digitally for immediate reading or as professionally illustrated, printed picture books, with prices starting at €4.90 including VAT. Printed books are delivered by post, typically within 10 to 14 days. Knuffel also offers an audiobook version of each completed story, featuring an AI-generated voice and the child’s name. Designed for shared reading and early readers, the books are intended for children from around two to three years old and can appeal through primary school.
