What are the four facts a premise needs?

A protagonist, a goal, a conflict and stakes: who the story is about, what they want, what pushes back, and what failing costs. The planner anchors each to the beat where a reader expects it and treats anything missing as a gap rather than a detail.

Why does the planner anchor the conflict to the midpoint?

Because the midpoint is where the opposing force shows its full strength; before it, the story is still promising the conflict, and after it, the ending has to answer for it. Anchoring the conflict there is what stops a premise from staying vague about who or what pushes back.

How does the planner choose beats when I change structure?

Each fact is matched to the nearest beat that is still free in the new structure, so the four anchors stay distinct. The remaining beats come from the structure's own beat list, which is why a hero's journey plan has twelve lines and a three-act plan has seven.

What does the logline check catch?

A logline under eight words. At that length it is usually a topic or an image rather than a story with someone in it, and every beat below will have less to answer to. The check reports the word count rather than rewriting the sentence.

Can the planner outline a whole novel?

It can shape one, not fill it. The anchors and prompts are as much as a premise supports; subplots, character arcs and scene-level turns come from you. Use the plan as an argument to test the premise before drafting, not as a substitute for the draft.

Checks

No logline; a plan needs one sentence for every beat to answer to.
No protagonist; a structure is a shape for someone's story.
No goal; without something wanted, the inciting incident has nothing to incite.
No conflict; a difficulty the protagonist could walk away from is not an opposing force.
No stakes; the second turning point needs a cost the reader can measure.

Scope and limits

The four anchors are the facts a premise needs — who it is about, what they want, what pushes back and what it costs. Each one is matched to the nearest beat of the chosen structure so the plan reads in order.

The planner arranges what you already know; it does not invent subplots, characters or scenes. The beats between the anchors are prompts, and a plan is not a draft — expect the story to argue with it.

The plot structure planner maps the four facts a premise needs — protagonist, goal, conflict and stakes — onto the beats of a chosen structure, so the whole beat sheet reads in order before a draft exists.

What is Plot Structure Planner?

The plot structure planner starts from the four facts a premise cannot do without: who the story is about, what they want, what pushes back, and what it costs if they fail. You write those facts once, choose a structure, and the planner places each one on the beat where a reader expects to meet it. The result is not a form full of prompts; it is a beat sheet with your own premise already sitting at the load-bearing points, and the structure's remaining beats around it.

The anchor points are deliberate. The protagonist arrives at the opening, because a structure is a shape for someone's story. The goal lands at the inciting incident, because that is the beat where a want becomes a journey. The conflict reaches the midpoint, where the opposing force shows its full strength and the story stops being the one the reader thought they were reading. The stakes take the second turning point, where the cost of failing has to become concrete enough to carry the final act. A plot structure is a set of promises; the anchors are where those promises come due.

Between the anchors, each beat keeps its own prompt from the structure you chose: the midpoint asks for the reversal, the second plot point asks for the cost, the resolution asks for the new normal. That is what makes the output a full beat sheet rather than four labelled slots. The three-act structure runs seven beats, the four-act five, the hero's journey twelve and Save the Cat fifteen; the planner matches each of your four facts to the nearest beat that is still free, so no two facts ever land on the same one.

Switching structure is a one-click experiment. Change from a three-act structure to the hero's journey and the same four anchors re-map to that structure's beats while the new beats appear with their own prompts. Writers use this to test whether a premise is a journey or a three-act story without rewriting anything; if the facts feel wrong on a structure's beats, that is information about the premise, not a formatting problem.

The checks are the planner's own. A logline under eight words states a topic rather than a story, so it is flagged with its word count. A conflict under four words names a difficulty rather than an opposing force. A missing fact is reported as missing, with a sentence about which beat it was supposed to carry. None of the checks touch your prose; they count and they name gaps.

What the planner cannot do is invent. It will not produce subplots, characters or scenes, and the beats between your anchors remain prompts until you fill them. Stakes that never appear in the draft, a goal that changes at the midpoint, a conflict that turns out to be weather rather than a force — the planner cannot see any of that, and a plan is not a draft. Treat the output as an argument to have with the story before you write it: if the four facts cannot carry the beats they are anchored to, no amount of structure will.

How to use Plot Structure Planner

Write the logline as one sentence you could say out loud.
Name the protagonist, the goal, the conflict and the stakes, one per field.
Choose the structure; switch it later to test whether the premise holds a different shape.
Read the beat sheet and fix any fact the check marks as missing or too thin.
Draft from the anchors first, then fill the beats between them.

When to use Plot Structure Planner vs related tools

Use the plot structure planner when a premise is firm enough to have a want and an obstacle but not yet a plan: before outlining, before a first draft, and before committing to a structure that will shape months of work. The plan hands off in two directions. Take it to the Story Beat Builder to track which beats are drafted, or to the Plot Point Mapper when you would rather start from the events you already have and see which structure they imply. If the premise itself is still thin, start with the Story Idea Generator instead.
