A story outline turns an idea into a plan you can write from. Give your premise, pick a genre, a structure (three acts, the hero's journey, seven points or 15 beats) and how many chapters, and the story outline generator gives you a working title, a logline, numbered chapters with what happens in each, and a short cast list.
How to outline a story with AI
1. Write your premise in a sentence or two.
2. Pick a genre, a structure and 5, 8 or 12 chapters.
3. Press Outline my story.
4. Keep what works, change what does not, and run it again for another path.
What you get
A working title and a logline, then numbered chapters grouped by the parts of your structure, each with a short title and what happens. It ends with 3 to 5 main characters and what each one wants.
Which structure to pick
Three acts is the simplest and fits most stories. The hero's journey suits quests and coming-of-age tales. Seven points is good for plot-driven stories with a strong turn. 15 beats suits screenplay-style pacing.
Need a plot first?
If you do not have a premise yet, use our AI plot generator to find one, then bring it here to plan the chapters.
