This is the one I heard about the most. You are editing your finished novel, you write an extra chapter yourself, and there is nowhere to put it - no way to slot it in between chapters 11 and 12 and push the rest down. Until now the honest answer was "you can't". It takes one click today. Here is how it works. Open your book in the builder. At the top of every chapter, next to the title, there is now an "Add chapter" button. Click it on the chapter that should come before your new one. An empty chapter appears right after it, everything below shifts down by one, and the whole book renumbers itself - the sidebar, the contents page, and your PDF, EPUB and DOCX exports all follow automatically. Then the new chapter asks you one question, with two buttons. "I'll write it myself" - the chapter opens empty and you type or paste in your own text. Nothing else happens. This is the one most of you asked for. "BookNova writes it" - and this one runs in two steps, on purpose. Step one: BookNova reads how the previous chapter ends and how the next chapter opens, and writes the PLAN for the chapter that goes between them. The plan appears in the chapter brief box, which is the same box you already use to steer any chapter. Read it. Change anything you want changed. Add what is missing, cut what you do not want. It is your text now. Step two: when the plan says what you actually want, you press "Write chapter text" and the chapter gets written from your edited plan. I split it into two steps for one reason. The plan is the only place where you can steer a chapter, and you should get your hands on it BEFORE the words are written, not after you have already spent credits on a chapter that went the wrong way. Step one costs you nothing. Nothing is written, and nothing is charged, until you press the second button. Because the new chapter is anchored on both sides - the ending before it and the opening after it - it cannot wander off or replay a scene you have already read. It has to land exactly where your next chapter begins.
