The queen she once tutored rides up the hill anyway: the great ward Wenna cast forty years ago, the one that ended the war with the river clans, is failing, and only its maker can renew it.

From a line to a plot
- Pick a genre. The genre carries the conventions: a cozy mystery needs a closed circle of suspects, a Regency romance needs a reason the couple can't simply say yes. The generator writes to them.
- Add one specific thing if you have it. A character, a place, an object or a problem: “a retired cartographer and a village the river took”. One concrete detail beats a list of adjectives.
- Generate, then read like an editor. Each plot lands on top of the stack, with a title. Keep the one with a protagonist you want to follow and a problem you can't solve in your head. Copy it, and press again.
What to do with a plot you like
Test it with three questions. Who wants what? What stands in the way? What does it cost if they fail? If the card answers all three, you have a premise. Next, find the turn that changes the story halfway through, and the ending the premise has been promising.
Our guide to the 10 essential story elements walks through the rest. When you're ready to outline, Chapterly has plot boards and character cards built into the writing studio.
Questions about the plot generator
Is the plot generator free?
Yes. There's no account to make and nothing to install. Pick a genre, press the button, and press it again as often as you like.
Can I use a generated plot in my own book?
Yes, use it however you like. Treat it as a premise rather than a finished plan: the book you actually write will drift a long way from the card, and that drift is where it becomes yours.
How do I get better plots out of it?
Give it one specific thing in the description: a person, a place, an object or a problem. "A night-shift nurse who finds a will in a patient's coat" steers it far better than "a mystery with twists". Then generate several and keep the one that makes you want to know what happens next.
What's the difference between a plot and a premise?
A premise is the situation and the question it raises: who wants what, and what stands in the way. A plot is the chain of events that answers it, scene by scene, through the turns to an ending. The generator gives you a premise with the first moves of a plot. The rest is the writing.
How is this different from the writing prompts?
A writing prompt gives you a moment to write today: a scene, a line, a situation. A generated plot gives you the shape of a whole story: a protagonist, what they want, what goes wrong and what it costs. Use the plot to plan a book and the prompts to warm up for a writing session.
Which genres does it cover?
56 subgenres across six shelves: thrillers and suspense, historical fiction, romance, mystery and crime, science fiction and fantasy, and contemporary fiction. Each subgenre has its own page with sample plots, a plotting checklist and answers to common questions.
