Story Arc Engine is a storytelling tool that breaks down any narrative into the five-part story arc. It lets you explore how a single plot change can shift the entire storyline and ending. You can choose from well-known titles or enter your own, even niche ones by including the author or director’s name. The best part is experimenting with “what if” scenarios—edit an event or randomize it and watch the story evolve. You can also begin with your own idea, and Story Arc Engine will expand it into a full narrative framework, giving you a strong base for your draft.
