What is the best story structure for a novel?

There is no single best one. Three-act structure is the most flexible; Save the Cat suits fast-paced commercial fiction; the Hero's Journey fits quests and transformations; Freytag's pyramid suits tragedy and drama. Many writers outline in one structure and check the draft against another.

What are the 15 beats of Save the Cat?

Opening Image, Theme Stated, Set-Up, Catalyst, Debate, Break into Two, B Story, Fun and Games, Midpoint, Bad Guys Close In, All Is Lost, Dark Night of the Soul, Break into Three, Finale, and Final Image. They come from Blake Snyder's Save the Cat! (2005), where each is placed on a page of a 110-page screenplay.

What are the 12 stages of the Hero's Journey?

In Christopher Vogler's version: the Ordinary World, the Call to Adventure, Refusal of the Call, Meeting with the Mentor, Crossing the First Threshold, Tests, Allies, Enemies, Approach to the Inmost Cave, the Ordeal, the Reward, the Road Back, the Resurrection, and Return with the Elixir. Vogler condensed them from Joseph Campbell's monomyth, which has seventeen stages.

What are the five parts of Freytag's pyramid?

Exposition, rising action, climax, falling action, and resolution — which Freytag, analyzing tragedy, called the catastrophe, and many classrooms call the denouement. He named the moment that sets the rising action going the exciting force, now usually called the inciting incident.

How is this different from the Writing Prompt Generator?

The Writing Prompt Generator gives you a random idea to start from. The Story Outline Generator starts from your idea — your protagonist, goal, obstacle, and setting — and turns it into a structured, beat-by-beat plan.

Does the story outline generator use AI?

No. Every beat prompt is hand-written and filled in with the details you enter; the tool does not invent plot or write prose. It runs entirely in your browser, so your story stays on your device.

Story Outline Generator

Choose a structure — three-act, the Hero's Journey, Save the Cat, or Freytag's pyramid — and describe your protagonist, their goal, the obstacle, and the setting. You get a beat-by-beat outline with a prompt for every beat built from your own story, placed at the right point in the manuscript if you give a target length. Honest templates, no AI.

Story Essentials

Protagonist:

Goal:

Obstacle:

Setting:

Theme:

1. Opening Image

Where: Act One · page 1 of Snyder's 110-page script

To write: A single snapshot of your protagonist's world before the story changes it — a scene you can mirror in the Final Image.

2. Theme Stated

Where: Act One · page 5 of Snyder's 110-page script

To write: Someone other than your protagonist hints at the lesson the story is about (the theme). your protagonist hears it but doesn't understand it yet.

3. Set-Up

Where: Act One · pages 1–10 of Snyder's 110-page script

To write: Show your protagonist at home, at work, and at play in the story's world. Plant every flaw and problem that will need fixing later.

4. Catalyst

Where: Act One · page 12 of Snyder's 110-page script

To write: The event that knocks your protagonist out of the status quo: news, an invitation, a loss, or a discovery.

5. Debate

Where: Act One · pages 12–25 of Snyder's 110-page script

To write: Your protagonist hesitates. Should they act? Can they? Show the doubt, and what staying put would cost.

6. Break into Two

Where: Act Two · page 25 of Snyder's 110-page script

To write: Your protagonist chooses to act — pursuing the goal (what they want) — and steps into an upside-down version of their world. The choice must be theirs.

7. B Story

Where: Act Two · page 30 of Snyder's 110-page script

To write: Introduce the second storyline, often a friendship or a romance, whose characters will help your protagonist learn the theme.

8. Fun and Games

Where: Act Two · pages 30–55 of Snyder's 110-page script

To write: The promise of the premise: the scenes a reader came for, as your protagonist explores the new world and tests themselves against what stands in the way.

9. Midpoint

Where: Act Two · page 55 of Snyder's 110-page script

To write: A false victory or a false defeat. The stakes rise, time may start running out, and the main story and the B story cross.

10. Bad Guys Close In

Where: Act Two · pages 55–75 of Snyder's 110-page script

To write: Enemies outside regroup and doubts inside spread. your protagonist's team frays, and the flaws from the Set-Up come back.

11. All Is Lost

Where: Act Two · page 75 of Snyder's 110-page script

To write: The opposite of the Midpoint: the lowest moment, often marked by a loss — what Snyder calls the “whiff of death”.

12. Dark Night of the Soul

Where: Act Two · pages 75–85 of Snyder's 110-page script

To write: Your protagonist sits with the loss. In the darkness, they finally understand the theme.

13. Break into Three

Where: Act Three · page 85 of Snyder's 110-page script

To write: A new idea — from the B Story or the theme — shows your protagonist the way forward, and they choose to fight again.

14. Finale

Where: Act Three · pages 85–110 of Snyder's 110-page script

15. Final Image

Where: Act Three · page 110 of Snyder's 110-page script

To write: The mirror of the Opening Image: show how much your protagonist and their world have changed.

How to Use the Story Outline Generator

1. Pick a structure. Three-act structure for a simple spine, the Hero's Journey for quests and transformations, Save the Cat for tightly paced genre fiction and screenplays, and Freytag's pyramid for drama and short fiction.
2. Describe the premise. Name the protagonist and say who they are, what they want, what stands in the way, and where and when the story happens. A theme is optional, but several beats use it.
3. Add a target length. Optional: enter a word or page count and each beat is placed at its approximate position — Save the Cat beats scaled from Blake Snyder's page numbers, three-act beats from the usual quarter marks.
4. Draft each beat. Every beat is a prompt to answer in a sentence or a paragraph. Copy the outline, download it, or print it, and keep it beside the draft.

Four Story Structures Compared

Structure	Where it comes from	Parts	Good for
Three-act structure	The beginning, middle, and end of Aristotle's Poetics, formalized for film in Syd Field's Screenplay (1979)	Setup, confrontation, resolution, with turning points near the 25% and 75% marks	Almost any story; the simplest spine
The Hero's Journey	Joseph Campbell's monomyth in The Hero with a Thousand Faces (1949), condensed by Christopher Vogler in The Writer's Journey	Twelve stages, from the Ordinary World to the Return with the Elixir	Quests, adventures, and transformation stories
Save the Cat	Blake Snyder, Save the Cat! (2005)	Fifteen beats placed on a 110-page screenplay	Screenplays and commercial fiction with tight pacing
Freytag's pyramid	Gustav Freytag, Die Technik des Dramas (1863)	Exposition, rising action, climax, falling action, resolution	Plays, short stories, and tragedy

The Save the Cat Beats and Where They Fall

Blake Snyder placed his fifteen beats by page number in a 110-page screenplay. The generator keeps those positions and scales them to your length: in an 80,000-word novel, the Catalyst lands around word 8,700 and the Midpoint around word 40,000.

Beat	Snyder's page	Share of the story
Opening Image	1	The very start
Theme Stated	5	≈ 5%
Set-Up	1–10	The first ≈ 9%
Catalyst	12	≈ 11%
Debate	12–25	≈ 11–23%
Break into Two	25	≈ 23%
B Story	30	≈ 27%
Fun and Games	30–55	≈ 27–50%
Midpoint	55	50%
Bad Guys Close In	55–75	≈ 50–68%
All Is Lost	75	≈ 68%
Dark Night of the Soul	75–85	≈ 68–77%
Break into Three	85	≈ 77%
Finale	85–110	≈ 77–100%
Final Image	110	The very end

Jessica Brody's Save the Cat! Writes a Novel (2018) adapts the beats to fiction with slightly different percentages. Treat every position as a guide, not a deadline.

Common Outlining Mistakes

Turns that happen to the protagonist rather than through them. The big moments — breaking into the second act, the final confrontation — land harder when they are choices the protagonist makes.
An obstacle with no face. “Society” or “fear” is hard to dramatize. Give the opposition a person, an institution, or a ticking clock.
A sagging middle. The long middle needs its own turn: the Midpoint should change the stakes, not just add another event.
Treating positions as rules. A Catalyst at 14% is fine. The percentages describe common practice; the story decides.
