📝 Three-Act Structure Planner

Map your story beats across a screenplay, novel, or short film. Choose your structure framework and get page/chapter targets for every key beat.

🎬 The 25/50/25 rule: Classical three-act structure divides the story into Act 1 (25% — setup), Act 2 (50% — confrontation), and Act 3 (25% — resolution). The midpoint (50%) divides Act 2 into two halves. This is the backbone of almost all commercial storytelling.
📌 Inciting incident vs plot points: The inciting incident (usually around 10–15%) is what disturbs the normal world. The first plot point (25%) is the point of no return — your protagonist commits to the conflict. The second plot point (~75%) is the dark night of the soul before the final push.
🦸 Active vs reactive protagonist: In Act 1 your protagonist is often reactive (events happen to them). In Act 2 they start making choices. By Act 3 they must be fully active — making the decisive choice that resolves the story. Passive protagonists in Act 3 produce unsatisfying endings.
