Why your child's name changes the story

Personalized books have existed for forty years. Almost all of them are a name printed into a fixed plot. Here is what changes when the name is there from the first sentence.

I spent nine years in children's publishing, four of them running a picture book imprint, and in that time I turned down hundreds of manuscripts that were too specific. A story about a girl with a hearing aid who is afraid of the swimming pool is a wonderful book for a small number of children and a difficult book to print ten thousand copies of. Publishing works on the average child, and there is no average child.

Personalized books tried to solve this and mostly did not. The format is nearly always the same: a fixed story with a name dropped into a slot, sometimes a face pasted onto a cartoon body. Children see through it fast. A five year old can tell the difference between a book about them and a book with their name in it, because the second one keeps saying the name and never notices anything else.

What actually has to move

When the name is present from the first sentence, other things follow. The rhythm changes: a two syllable name lands differently at the end of a line than a four syllable one. The illustrations change, because a child in a wheelchair meets the top of a staircase differently than a child who runs up it, and that is a plot event, not a detail. The ending changes, because the small brave thing at the end of the book should be the thing this child would find brave.

None of that survives a template. You cannot slot it in later. It has to be written knowing who the book is for, which until recently meant one author writing for one child, which meant it did not scale past a birthday present made by a very patient aunt.

The part that is new

A language model can hold a brief of forty words about one child and write a whole book that is shaped by them. That is the only reason Quillow exists. We did not add a model to a publishing product. There was no publishing product to add it to, because at one book per child the economics never worked.

The thing we watch for now is the opposite failure: a story so tuned to one child that it is only a mirror. Good books for children are windows too. So the brief goes in, and the story goes somewhere the parent did not ask for, and the child is the one who goes there.
