narrative-simulation

emergent narrative platform

Open-source narrative simulation engine with branching character and world-state modeling.

Simulation in, prose out. A deterministic engine for narrative simulation: characters live turn-by-turn on a rule-based state machine, an LLM only acts and writes, and the novel is a cut of the recorded lives — so the book cannot contain what didn't happen.
