What You Can Do

Upload your screenplay outline or existing script to deconstruct its three-act structure, beat-by-beat pacing, and character arcs. Claude identifies structural weaknesses, plot holes, and pacing problems before you invest months in rewriting. Get a detailed story map that shows exactly where your narrative needs reinforcement and which story elements will resonate with audiences.

Features

Three-Act Structure Analysis

Maps your story against classic structure models (Hero's Journey, Save the Cat, Three-Act) and identifies where key turning points should land for maximum impact.

Beat Sheet Generation

Converts your outline into a detailed beat sheet with scene-by-scene breakdowns, showing story momentum, character development, and narrative progression.

Pacing Analysis

Evaluates page count against story beats to ensure proper pacing—catches rushed climaxes, saggy middles, and exposition overload.

Plot Hole Detection

Scans for logical inconsistencies, unresolved character motivations, and narrative gaps that audiences will notice.

Character Arc Tracking

Maps how each character's journey aligns with story structure, ensuring character goals drive plot events and resonate emotionally.

Scene-by-Scene Breakdown

Creates an inventory of every scene showing purpose, function (exposition, conflict, climax), and connection to overall story.

Story Convergence Mapping

Visualizes how multiple storylines interweave, identifies orphaned subplots, and shows optimal moments for narrative convergence.

Example Output

Beat Sheet Analysis

Act One (0-30 pages)

  • ✓ Inciting Incident: Page 12 (strong setup)
  • ⚠ Crossing the Threshold: Page 28 (consider moving to page 25 for momentum)

Act Two (30-75 pages)

  • ✓ Midpoint Plot Turn: Page 50 (excellent placement)
  • ⚠ B-Story Integration: Pages 40-50 feels disconnected from A-Story
  • ✗ Rising Conflict: Plateau at pages 60-68 (add obstacle or reveal)

Act Three (75-110 pages)

  • ✓ Climax: Page 95 (strong convergence of all threads)
  • ⚠ Resolution: Pages 105-110 feels rushed (add 3-5 pages for emotional payoff)

Plot Hole Audit

  1. Page 34: Protagonist mentions "never learned to drive" but operates getaway car in Act Two chase. Resolution: Add dialogue establishing driving ability in Act One.
  2. Page 67: Antagonist's motivation shift unexplained. Add clarifying scene before page 65.
  3. Page 82: Secondary character disappears; unresolved subplot. Either resolve or remove character.
