AI RPG Engine Build worlds. Simulate them. Improve them.

Deterministic Simulation

Tick-based engine with world state, events, perception, cognition, faction beliefs, rumor propagation, and seeded RNG. Every run can be replayed exactly.

AI-Assisted Worldbuilding

Scaffold rooms, factions, quests, and districts from a theme. Critique designs, repair schema errors, and guide multi-step builds. AI suggests — you decide.

Replay Analysis

Structured findings explain why events happened, where mechanics break down, and which systems create instability. Analysis feeds directly into tuning.

Experiment-Driven Balancing

Run batches of simulations across seeds. Detect variance, sweep parameters, compare tuned vs baseline. Turn world design into a testable process.

Studio Workflow

CLI design studio with dashboards, issue tracking, experiment browsing, session history, guided onboarding, and context-aware command discovery.

17 Built-In Modules

Combat, dialogue, cognition, perception, factions, rumors, districts, progression, environment, and more. All composable, all deterministic.

Genre-Agnostic

Same core runs dark fantasy, cyberpunk, or any setting. Genre belongs to rulesets and content packs, not the engine.
