Fill in three fields and get your complete novel structure, chapter by chapter: which act each one belongs to, how many words it should run, and which story beat lands there. Choose three acts, Save the Cat or the Hero's Journey.
Almost every story that works shares the same skeleton: three acts. A setup covering the first 25%, a confrontation filling the central 50%, and a resolution in the final 25%. What changes between models is not the shape but the level of detail.
If there's one reason novels get abandoned halfway, it's the sagging second act: 40,000 words in which the protagonist circles without anything really changing. The fix sits exactly at the middle of the book.
The midpoint is a twist that changes the story's direction: a false victory that will turn out poisoned, or a false defeat that actually gives the protagonist what they needed. Its job is to turn them from reactive (things happen to them) into active (they make things happen). Put a real twist there and the second act stops sinking.
There's no fixed rule, but for an 80,000-100,000 word novel 25 to 40 chapters is typical, giving chapters of 2,000-3,500 words. More important than the count is consistency: similar chapter lengths create a comfortable rhythm, and shorter ones accelerate reading through tense stretches.
The tool above splits your words across chapters and places each beat in the chapter where it belongs, so you can see at a glance where every turning point should land.
Having the structure is the first step, and it isn't the hard one. The hard part is the 80,000 words that follow — and above all keeping them coherent: a character not changing name by chapter 20, the subplot you opened in chapter 4 actually closing, the tone holding.
That's exactly what YourNovel.app does: it starts from a structure like this and writes the whole book with Holistic Memory that remembers the entire work, so chapter 30 still knows what happened in chapter 1. To go deeper into the method, see our guide on how to organize a novel.
In three acts: setup (25%), confrontation (50%) and resolution (25%), with turning points separating each stretch. Save the Cat and the Hero's Journey detail that same shape with more beats.
Typically 25-40 chapters for 80,000-100,000 words, i.e. 2,000-3,500 words per chapter.
The twist at the 50% mark that changes the story's direction and turns the protagonist into an active agent. It's what prevents a sagging second act.
Not mandatory, but it greatly reduces the risk of abandoning the manuscript halfway, which is where most unfinished novels stall.
