What Story Structure Planner does, with a checked example
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.
Worked example
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.
