The audience you pick on the create screen changes vocabulary, sentence length, themes, what can appear on the page and how long the book is. It is one of the strongest steering controls BookZeta has, and the most commonly left on a default.

BookZeta has six audiences: 1-4, 5-9, 10-12, 13-17, Adult and All Ages. This is what each one means in practice.

Ages 1 to 4: toddlers and preschoolers

Very short, very repetitive, read aloud by an adult rather than by the child.

• Simple, concrete nouns. Things a small child has seen.
• Heavy repetition and rhythm. Repeated phrases are a feature, not padding.
• One idea per page. Often one sentence per page.
• No real jeopardy. Problems are small and solved warmly.
• Typically 10 to 16 pages.

Illustration carries most of the story at this age, so this band belongs in Graphic Mode. Read-along audio is generated automatically for these books, which matters more here than anywhere else, because the reader is usually listening rather than reading.

Ages 5 to 9: young children

Early readers and first chapter books. The child may be reading some of it themselves.

• Short sentences, mostly familiar words, with a few new ones in clear context.
• A real but gentle problem, solved by the child character rather than by an adult.
• Humour works extremely well. So does a repeated structure.
• Scary is allowed if it resolves safely.
• Picture books 16 to 32 pages; early chapter books longer with short chapters.

Ages 10 to 12: pre-teens

Middle grade. The most demanding band to write well, and the one most often written down to.

• Full sentences and real vocabulary. Children this age read far above the level people expect.
• Genuine stakes: friendship, fairness, loss, being an outsider, families that are not simple.
• The protagonist should be at the top of the age band or slightly older. Readers read up.
• Adults stay out of the way. The child solves it.
• No explicit content, and romance stays at the level of a crush.

The common mistake is a simplified plot with a moral at the end. Middle grade readers detect being taught at and resent it.

Ages 13 to 17: teenagers

Young adult. Adult-level prose with a teenage protagonist and a teenage frame of reference.

• Emotional intensity, identity, autonomy, first relationships, the beginnings of real consequences.
• Voice matters more than in any other band. First person is common for that reason. See point of view.
• Difficult subjects are permitted and expected, handled seriously rather than explicitly.
• Horror, thriller, fantasy and romance all work here.

Adult

No content restrictions beyond the platform rules, full vocabulary, full complexity, any genre. This is the default for novels, and the required setting for horror and for most thrillers.

All Ages

A family audience: readable by children, enjoyable for the adult reading it aloud. Useful for fables, animal stories and illustrated books meant to be shared. It is a genuine choice, not a neutral one, so do not use it to avoid deciding.

Picking the right one

Match the audience to the reader, not to the protagonist's age and not to your own taste. A book about a twelve-year-old can be written for adults, and often is.

Two questions settle most cases:

1. Who is holding the book? If an adult is reading it aloud, you are in 1-4 or 5-9.
2. What is the worst thing that can happen in this story? If the answer is serious, you are at 13-17 or Adult, whatever the protagonist's age.

What happens if you get it wrong

The mismatch shows up immediately in the generated text, and it is easy to recognise:

• Audience too young produces flat, over-explained prose with the tension removed, and a plot that resolves too easily.
• Audience too old produces vocabulary and situations that do not belong in a children's book, which is a problem for the reader and for the stores you publish to.

You can change the audience in project settings and regenerate, but it is much cheaper to get it right before the first generation than to rework a finished draft.
