What You Can Do

You can convert a premise or logline into a complete three-act story architecture with identified turning points, beat breakdowns, and character motivation analysis. Claude helps you diagnose structural problems like sagging middles or unearned endings, reverse-engineer successful films in your genre, and stress-test whether your protagonist's external goal aligns with their deeper character need.

Features

Beat sheet generation

Claude breaks down your story into Act 1 (Setup), Act 2a (Rising Action), Act 2b (Midpoint), Act 2c (Escalation), and Act 3 (Resolution) with specific plot points identified

Character arc mapping

Develop how your protagonist's emotional and thematic journey intersects with plot mechanics, showing growth or change across the three acts

Turning point analysis

Identify and stress-test inciting incidents, plot points at 25% and 75%, and climactic moments to ensure adequate escalation

Logline-to-structure translation

Convert your premise into a structured narrative with clear stakes, conflict mechanics, and thematic resonance

Comparative structure analysis

Reverse-engineer how successful films in your genre employ three-act principles and apply those patterns to your own story

Conflict and motivation alignment

Ensure your protagonist's goals drive the plot and that external plot mechanics reinforce internal character transformation

Resolution coherence check

Verify that your ending genuinely resolves the central conflict and thematic questions rather than merely stopping the action

Example Output

Input: "A burned-out insurance adjuster discovers her estranged father's letters revealing he was a con artist—she must decide whether to expose his legacy or protect her family's reputation."

Output includes:

  • Act 1 (Setup): Establish adjuster's risk-averse life, inciting incident (discovery of letters) at page 10-12
  • Act 2a (Rising Action): Investigation deepens, she interviews con artist's victims, discovers her own complicity in family silence
  • Midpoint (45-50 min): She finds evidence her father stole from her mother; external stakes raise as a journalist contacts her
  • Act 2b (Escalation): Confrontation with family members, moral dilemma sharpens
  • Act 3 (Resolution): Her choice to expose truth redefines her relationship to risk, legacy, and family loyalty
  • Character Arc: Fear of scandal → acceptance of moral ambiguity → courageous authenticity
  • Thematic Alignment: Plot mechanics (uncovering secrets) reinforce theme (defining yourself beyond family inheritance)
