Start with the experience, not the branches
Before generating scenes, decide what the reader should be able to influence. Can they change a relationship, uncover information or determine how a conflict ends? Write a one-paragraph premise that names the reader’s role, the central problem and the boundaries of their control. Those boundaries prevent a promising story from expanding into more paths than you can finish.
Choose a small format for the first version: an opening, two or three decision points and a few endings. Give each choice a consequence the reader can notice later. A decision between two nearly identical lines of dialogue may add work without adding much agency; a choice between protecting an ally and pursuing a clue gives you something to build on. Ask an AI assistant for possible decisions, then keep only those that serve the experience you want to create.
Draw a map before writing prose
Represent the story as connected scenes. Give each scene a short identifier, such as OPENING or ARCHIVE, and note where each available choice leads. A simple list is enough: scene, information revealed, choices offered and destination for each choice. Mark any paths that rejoin, along with what must be true for the shared scene to work.
Paths can rejoin without making earlier choices meaningless. For example, two routes might lead to the same meeting, but the reader arrives with a different ally or a different piece of information. If you ask AI to propose a map, give it your premise and a limit on decision points and endings. Review the result for dead ends, choices that lead to the same outcome and scenes that depend on knowledge the reader may not have. Fix the map before asking for polished dialogue.
Keep a compact record of story state
A branching story becomes difficult to manage when later scenes depend on earlier decisions. Create a state sheet with a few variables you can check: which clue was found, whether an ally trusts the reader and whether a key object is available. Define each variable clearly. If trust can only be yes or no, avoid describing it as a subtle scale in one scene and an on-or-off condition in another.
For each scene, record what must be true when the reader enters and what can change before they leave. You can give an AI assistant this short record when requesting a draft, rather than pasting in the entire manuscript. For example: “The reader has not seen the letter. The ally is wary. Draft this scene without revealing the letter’s contents.” Treat generated prose as a candidate, not a continuity check; compare it with your map and state sheet yourself.
Draft choices that make a clear promise
A choice label should tell readers what action they are taking, even if its full outcome remains uncertain. “Ask the guard about the missing courier” is easier to evaluate than “Take a chance.” Make sure the next scene follows through on that action. If the reader chooses to leave a room, do not quietly place them back inside it because a drafted passage needs another conversation.
Use AI to generate alternatives for a difficult decision point, then assess them with three questions: Is each option understandable from what the reader knows? Does it express a different priority or strategy? Will the difference matter later? You do not need a unique ending for every choice. A changed line, resource or relationship can be enough, provided it feels deliberate and remains consistent. Keep the final wording of choices under close human review because a small ambiguity can change what readers think they agreed to do.
Test complete paths, then revise the map
Read the story one path at a time, making only the choices a reader could make on that route. Keep a short log of the scenes visited and state changes. At each transition, check whether the reader has the required information, whether the available choices make sense and whether a previous decision is acknowledged. Repeat with paths that reach shared scenes from different directions; those junctions are common places for contradictions.
An AI assistant can help you test by following a supplied route and flagging apparent continuity problems. Give it the relevant scenes, map and state rules, and ask it to distinguish a definite contradiction from a question that needs your judgment. Then verify each flag against the actual text. After testing, simplify where needed: remove branches that add little, repair unclear choice labels and update the state sheet whenever a revision changes the rules. A manageable story with dependable consequences is more satisfying than an elaborate map you cannot reliably maintain.
