What does "Write the title, subtitle, welcome and section names" do?

In "The book" card, describe the reader in "Who is it for? (optional)" (for example "a 6 year old who loves animals") and click it. Your AI engine drafts a title (that says mazes), a subtitle (what is inside), a warm welcome for the first page and a short name for each level's page, in the book's language and fitted to the book's mazes, levels and readers. The welcome goes into "Welcome page" and the names into the level boxes. Read them before you publish; the mazes are never touched by AI.
