A gamebook that writes the next page
A classic choose your own adventure book gives you two or three options at the bottom of a page and a fixed set of endings. This generator has no map written ahead of time. The story is told in the second person, and when it reaches a decision it offers suggested next moves. Pick one, or type something no gamebook would allow, such as asking the captain about the scar on her hand, and the next scene is written from that.
From your opening to the first fork
Start with where your character is and the problem in front of them. The AI asks up to three follow-up questions with options to pick from, and those are the first choices of your story: who you are, what you want, how the first scene opens. You can also type your own answer or skip. Then choose the heat and the chapter length, and keep choosing in the full app after a free sign-up. Short chapters bring the next fork around quickly.
