How to outline a book

Start with what you already know, not with chapter one. Crime novelist Harry Bingham suggests drafting your first outline under five headings1: status quo, inciting incident, developments, climax and resolution. Fill in what you can, and leave a question where you can't. Then write the core in four lines: who your protagonist is, what they want, what stands in the way and what failure costs. For nonfiction, the core is a promise: what your reader will be able to do by the end.

Next, place the big turns. K.M. Weiland, author of Structuring Your Novel, puts the three most important plot points at roughly the 25%, 50% and 75% marks2. In a 20-chapter novel, that's chapters 5, 10 and 15: the point of no return, the midpoint and the lowest point. Bingham warns that the long middle is where you'll struggle most, and the midpoint anchors it. Give every remaining chapter one job, like raising the stakes or exposing a secret, and cut any chapter that changes nothing. The novel outline template has those turns in place.

A nonfiction book outline swaps turns for takeaways. Jerry Jenkins, author of 21 New York Times bestsellers, suggests a one-sentence synopsis for each chapter3, ordered in stages so the chapters flow. Later, grow each into a few sentences and list the stories you'll use. A memoir, he adds, needn't be chronological: order the stories to serve your theme. If you'll sell the book on a proposal, publishing veteran Jane Friedman suggests a chapter outline of 3,000 words or fewer4. Treat it all as fluid, as Jenkins says: expand, condense or reorder as you go.

How it works

What is a book outline generator?

A book outline generator turns your idea into a chapter-by-chapter plan you can draft from. Type a sentence about your book in the box at the top of this page, or paste your notes or a rough outline; a file works too. River works out whether you're writing a novel, a short story, a memoir or nonfiction, and reads the genre and tone from your words. It keeps every name, scene and chapter count you give it, and puts the scenes you already know where they fit.

For fiction, you get a working title, your premise in one line and the core: who wants what, what blocks them and what failing would cost. Then come 20 chapters in three acts, or the number you ask for. Each has two or three beats and a job tag, such as "point of no return." Where River assumed something important, like the ending, it leaves a comment. It won't invent a secret sibling or sudden amnesia your idea doesn't support; big open choices become questions for you.

Memoir follows the same layout, but River never invents an event, a person or a line of dialogue. A nonfiction book gets a reader promise, one takeaway per chapter and a short list of the stories, examples or sources you'll need to supply. The outline lands as a doc in your River workspace, with buttons to draft chapter 1, check the outline or change it. Once chapter 1 exists, the chapter writer turns each later chapter's beats into scenes in your voice.

How it works

From your idea to a chapter plan

  1. Describe your book

    Write your idea in a sentence or paste notes. Add a chapter count, subgenre or short-story length if you like.

  2. River reads it

    It tells a novel from a short story, memoir or nonfiction, and infers genre, audience and tone.

  3. Get your outline

    A chapter list lands in your workspace, each chapter with its beats or takeaway, plus questions only you can answer.

  4. Edit and keep going

    Change anything, ask River to check the outline for weak spots, or have it draft chapter 1.

Example

  2. 3The Name on the TicketInciting incident
  3. 5Lines CastNo going back, about 25%
  4. 10Fog BankMidpoint, about 50%: she tells him
  5. 15BoardedLowest point, about 75%

What you'll get

A chapter plan with scene beats and a job for each chapter

  • A chapter-by-chapter plan for a novel, memoir or nonfiction book
  • Scene beats and a job for every chapter, with the big turns marked
  • Open questions for you to decide, not stock twists

Before and after

Your idea in. Twenty chapters, each with beats and a reason to exist.

What you give (example)

A retired ferry captain agrees to smuggle one last passenger across the strait, and the passenger is the son she gave up. She's Maren, 63. The harbor police already watch her boat. Her old first mate, Ivo, is the one who tips them off. I know they get stranded in fog halfway across. Ending: bittersweet. She gets him ashore, then turns the ferry back alone.

Your outline (excerpt)

Act I 1. Last Run. Maren ties up the ferry for the last time; a stranger offers cash for one crossing; she turns him down. Job: what she wants. 3. The Name on the Ticket. The passenger's papers carry the surname she gave away; she takes the job after all. Job: inciting incident. 5. Lines Cast. The harbor police arrive early; she cuts the mooring lines with him aboard. Job: no going back (about 25%). Act II 10. Fog Bank. Stranded mid-strait; the engine dies; she tells him who she is. Job: midpoint (about 50%). Open question for you: is he running from the law, or toward her?

The outline asks the big questions. You get to answer them.

What lands in your doc

What lands in your outline

  • Twenty novel chapters in three acts, or your own count, each with two or three scene beats
  • A job tag on every chapter, with the point of no return, midpoint and lowest point labeled
  • Memoir chapters built only from what you tell River, with each gap left as a question
  • A promise to your reader and 7 to 12 nonfiction chapters, each naming what the reader can do
  • Questions on the big choices that are yours to make, in place of invented twists
  • An outline check on request: chapters that change nothing, a sagging middle and unpaid setups

Questions authors ask

Common questions

How do I outline a book with River?

Describe your book in the box at the top of this page. One line is enough, though notes, a rough outline or a file give River more to build on. Press "Outline my book" and sign up when asked. River then writes the outline into a doc in your free workspace, where you can edit it, have River check it or draft chapter 1.

How detailed should a book outline be?

Detailed enough to draft from, and no more. Novelist Harry Bingham says a plot outline can be as short as a single page or run to 10 or 20 pages1. Either way, he says, it only has to be functional, clear and brief. River's outlines run about 1,200 to 2,000 words: two or three beats or points per chapter, plus a line on what each chapter is for.

Do I need an outline before I start writing?

For nonfiction, usually yes. Jerry Jenkins calls an outline non-negotiable for nonfiction3, because agents and acquisitions editors require one in a proposal. Novelists differ. Jenkins writes his own novels without one, and Harry Bingham does the bare minimum1, though he knows writers who draft a 30-page synopsis first. Unsure? A one-page plan that places the big turns shows early whether your middle holds up.

How many chapters will my outline have?

A novel gets 20 chapters unless you ask for a different number, and nonfiction gets 7 to 12, as the subject needs. To choose your own count, divide your target length by a typical chapter. Harry Bingham counts 2,000 to 4,000 words as a standard chapter5 in an adult novel, so an 80,000-word draft would have 20 to 40 chapters.

Does it work for nonfiction and memoir?

Yes. For a how-to, business or self-help book, the outline opens with a promise of what your reader can do by the end, and each chapter builds on the last. A memoir's chapters come only from what you share, and each gap becomes a question such as "What happened the night you left?" Prefer to work by hand? Try the memoir outline template.

Does it work as a story outline generator for short fiction?

Yes. Say it's a short story, or give a length under about 20,000 words, and River outlines it as 5 to 10 numbered scenes instead of chapters. Each scene gets its beats and what it changes, building to one turn and an ending. When the plan feels right, the AI story generator can write the whole story.

Is the book outline generator free?

Yes, it is free to start, and no card is needed. Your outline opens in a River workspace, where you can edit it, share it or ask River to change it. Paid plans add more AI use and access to the most advanced models.
