Director's Cut is an emotion-adaptive film engine that turns passive viewing into a personalized story. A short mystery plays on screen while your webcam silently reads your facial expressions every 10 seconds — Gemini Flash analyzes whether you're engaged, tense, bored, or surprised in real time. A Director Agent weighs your emotional arc against the story's branching structure and picks the path most likely to unsettle, move, or captivate you specifically. Scene visuals and narration are then regenerated on the fly to match your mood, delivered through a low-latency WebSocket loop. The result: no two screenings are
alike, and the film always knows exactly how you feel.
