Build a web-based screenplay writing tool. 1. Provide a distraction-free editor that enforces screenplay format: scene headings, action, character, dialogue, and parentheticals, with auto-capitalization of intros. 2. Store scripts in Fountain markup and offer one-click import and export for Fountain (.fountain) and Final Draft (.fdx) files. 3. Add a beat sheet view: each scene becomes a card with a summary the AI writes, drag and drop to reorder, with the script text updating. 4. Add AI tools in a side panel: rewrite the selected scene in a chosen tone, punch up flat dialogue, and suggest what happens if a scene is cut. 5. Add a continuity checker that scans the script for character name inconsistencies, time-of-day conflicts in scene headings, and characters who vanish for long stretches. 6. Track page count with proper screenplay pagination estimates and a target length setting (feature, pilot, short). 7. Support a title page editor with WGA-style fields. 8. Keep version history so writers can restore earlier drafts. 9. Make the AI suggestions opt-in: never modify the script without an explicit accept.
