In short

Children imagine endless worlds, but a bookshelf only holds the stories already written. Here any world can be created, at will.

The problem

A bookshelf only offers the stories someone has already written. The worlds children imagine have no limit, but the books that tell them do, and a story set in the exact world a child has in mind usually does not exist yet.

How it works

A character, a place and a theme become a complete, illustrated fairy tale set in any world you imagine, written by a large language model in under a minute. The reader's age is part of the request, so the language and the story fit the child who will hear it.

Every page gets its own illustration, generated for that page of the story. Each finished tale is saved to a personal library, and the popular stories other families created are there to read as well.

The outcome

TheFairytale.App is live at thefairytale.app, with the interface and the stories in Greek. There is a free plan, and paid plans for more new stories each month. Aplis AI built it end to end: the interface, story and illustration generation, sign-in and subscriptions.
