Plan stories using three-act, Hero Journey, Save the Cat, or Freytag pyramid structures.
The guide
A story outline becomes a skeleton the moment its events are sorted into named stages, and that is this tool's whole job. You pick one of four structures - three-act, Hero's Journey, Save the Cat, or Freytag's pyramid - and place your plot beats into that structure's slots, so the result reads as a complete arc. The surprise is that the structures disagree: Freytag puts the climax at the pyramid's peak, roughly halfway through, while three-act puts it near the end, and Save the Cat's beats carry page percentages built for screenplays. Treat the mapping as diagnosis, not a verdict, and nothing you type is uploaded.
A concrete input and expected output from the current implementation.
Input
Structure: Freytag's pyramid. Story: The Three Little Pigs - three pig brothers leave home and build houses of straw, sticks, and bricks. A wolf blows down the straw house and the stick house; the two pigs escape to the brick house. The wolf fails to blow it down, so he climbs to the roof and comes down the chimney, landing in a pot of boiling water. He flees, and the pigs live safely.
Expected output
Exposition: The pigs leave home; each builds a house; the wolf arrives. Rising action: The wolf blows down the straw house, then the stick house; each pig escapes to the brick house. Climax: The wolf cannot blow down the brick house and commits to entering through the chimney. Falling action: The wolf climbs to the roof and lowers himself down the chimney. Denouement: He lands in the boiling pot, flees, and the pigs live safely.
Freytag's pyramid has exactly five stages, and each event of the fable falls into its natural slot: the wolf's decision to use the chimney is the turning point, so it holds the peak position, with two escalating losses before it and the descent and escape after it.
Each structure arrives with a set number of slots: Freytag's pyramid has five parts (exposition, rising action, climax, falling action, denouement), three-act has setup, confrontation, and resolution, the Hero's Journey has twelve stages, and Save the Cat has fifteen named beats. Your story's events are sorted into these slots in order, and the finished plan is the full arc from first page to last.
Slots are not empty boxes: the catalyst starts the conflict, the midpoint reverses it, the all-is-lost moment strips the hero of what they just gained. Assigning an event to a slot is therefore a claim about what that event does in the story, not just where it falls. The same event reads as a setup step under Freytag or a midpoint turn under three-act, and the meaning shifts with the slot.
Only if you let the slots write the story. The structures describe patterns found across many published stories; they do not compel any specific content. Use the plan to spot where a turn is missing or misplaced, then fill it with your own events. If your story deliberately refuses a stage, that can work - the final call is yours, not the tool's.
Mainly where the climax sits. Three-act divides the story into setup, confrontation, and resolution, with the climax near the end. Freytag spreads the same material over five parts - exposition, rising action, climax, falling action, denouement - and places the peak about halfway, with a long falling action after it. Same events, different emphasis.
