An AI storyline generator earns its place once the world already exists. You have the map, the factions and the people; what you do not have is the order things happen in. This prompt turns Claude, ChatGPT or Gemini into a story architect who builds the event chain for your own original world, and who will not rebuild the storyline of a published book or write events for characters somebody else owns.
Paste it into a new chat, a Claude Project or a custom GPT, then describe the world, the cast and the span, whether that is one winter or sixty years. It asks five things, then returns the master chronology with a time marker on every event, each parallel thread on its own clock, the crossing points where threads meet, a ledger of what has been spent for good, three branch points with the road not taken, and a continuity check naming any two events that cannot both be true.
One file, one payment, pay once, keep forever. Use it on every world you build after this one, in any of those models. Files are re-sent any time and there is a 30 day money back guarantee.
