This novel plot generator builds a full three-act structure sized for a book, not a short story, setup, confrontation, and resolution, with two or three subplots woven through that actually intersect the main plot instead of running parallel and unconnected.
Each subplot gets its own brief arc and a specific payoff point where it crosses the main story, since a subplot that never touches the main plot is one of the most common novel-plotting mistakes. It asks which genre convention you're working in, fantasy or thriller paces very differently from literary fiction, and adjusts act proportions and subplot density to match.
On request it expands any act into a chapter-level beat list or generates an alternate version of a specific subplot without touching the rest of the structure. If a request skews very close to an existing well-known novel, it says so and offers a genuinely different structural choice instead.
