Caller sends a POST request with a topic, genre, and optional act count/tone\n2. Code validates the input and maps the genre to tone, pacing, and style guidelines\n3. AI generates a story outline: title, logline, themes, full character profiles, and an act/scene breakdown\n4. AI expands that outline into a complete script \u2014 full dialogue and stage directions per scene, with emotional beats noted\n5. AI generates production notes: staging, lighting/sound ideas, costume/set direction, casting notes, runtime estimate\n6. Everything is merged into one structured JSON object\n7. The request is logged to Google Sheets for tracking\n8. Webhook returns the complete script as JSON to the caller\n\n### How to set up\n1. Import this workflow into n8n\n2. Add your OpenAI credentials to all three OpenAI Chat Model nodes\n3. Add Google Sheets OAuth2 credentials and replace YOUR_SHEET_ID in the logging node\n4. Activate the workflow and POST a test request with topic, genre, numberOfActs, and tone\n\n### Requirements\n- OpenAI API key (GPT-4.1 or above recommended for long-form dialogue)\n- Google Sheets with OAuth2 credentials (optional, for logging)\n\n### How to customize\n- Adjust genre style guidelines in Code - Validate & Configure Genre Style\n- Change default act/scene counts per genre\n- Swap the three-stage AI pipeline for a single mega-prompt if you prefer fewer tokens/lower cost\n- Add a fourth AI stage for a cold open / teaser scene\n- Swap Google Sheets logging for Airtable or Notion\n- Add a translation step to deliver scripts in other languages\n\n### Google Sheets Column Layout\nSet up your ScriptRequests tab with these headers in row 1:\nRequest ID | Date | Timestamp | Topic | Genre | Title | Number Of Acts | Number Of Scenes | Word Count | Status" }, "typeVersion": 1 }, { "id": "8dfb1239-a8d5-4d63-a0ef-95843fa0b993", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ 3120, -464 ], "parameters": { "color": 3, "width": 932, "height": 720, "content": "## 1.
