Build a Choose-Your-Own-Adventure Story With AI

The moment a branching story clicks is when your child realizes they can trap the reader. Two doors, both terrible. That grin is the whole project.

How it goes

1. Pick a world in one sentence. A submarine that has lost its captain. A school where the lockers talk. Your child decides; nobody types anything yet.
2. Map it on paper before the screen. One sticky note per scene, arrows between them. Three or four scenes deep is plenty for a first attempt. This is the part most people skip, and skipping it is why branching stories collapse.
3. Write scene one by hand. Four or five sentences, ending in two choices.
4. Now bring in the AI, as the world rather than the writer. Set it up like this: You are the submarine. I will tell you what I do. Answer as the submarine, in two or three sentences. Never tell me what happens next. Your child describes an action and the world answers back.
5. Your child writes what they keep. The AI’s reply is raw material. Some of it goes on the sticky note in their words; most of it does not.
6. Test the map. Read a path aloud together and find the branch that leads nowhere. There will be one.

Who does what

AI plays the setting, invents obstacles when asked, and answers questions your child aims at the world.

Your child decides the plot, writes every sentence that ends up in the story, and rules on which ideas are any good.

You hold the account, read the replies before they land, and stay useless on purpose when your child asks what should happen next.

Make it easier or harder

For a seven-year-old: two scenes deep with two choices each, which is four endings. Any deeper and the map stops fitting on the table and the project ends unfinished.

For a twelve-year-old: require two branches to reconverge on the same scene, so different routes reach the same place having learned different things. Reconvergence is what real branching narrative does and it is far harder to write than a pure tree.

Take it off the screen

Copy the finished branches onto index cards, punch a hole in the corner, and ring-bind them. A reader picks a card, makes a choice, and hunts for the next one. Siblings and grandparents will play this for longer than you expect.

For a bigger version, tape the sticky notes to a wall as a map and let visitors walk the story.

When it goes sideways

Branches that lead nowhere are guaranteed, and hunting them is the best part. Read every path aloud with a finger on the sticky notes; any note with no arrow leaving it either needs an ending written or needs deleting.

If the world character starts narrating what happens next despite the instruction, restate it and shorten the leash: Two sentences maximum. Describe only what I can see and hear. Never say what I do. Long replies are where the model takes over the story.

One thing to watch

Branching stories tempt kids to ask the AI for “a scary bit,” and models vary in what they consider scary for a nine-year-old. Keep the screen where you can see it, and agree in advance on what happens if something lands wrong. Our guide to when AI shows something upsetting has the sentence we use.

ChatGPT and Gemini set thirteen as their minimum age, and Claude requires eighteen, so this runs on your account with you in the room.
