One living model
Build a world. Run it forward.
Keep assumptions visible while the world changes around them. Pause, rewind, branch or ask the copilot to reshape the model.
Build on an infinite canvas
Drag from 200+ worldbuilding nodes and wire them with causal edges: influences, feeds, inhibits, triggers.
Or just describe it
Tell Omida a world in plain language. The copilot lays out the system and tunes it as you talk.
Run it forward, live
Watch ticks stream by with events, metrics and narrative, then pull a thread to seed the next run.
