visionOS · One-time purchase · No subscriptions
Worldline Arc turns Earth into a source-backed spatial story engine for visionOS. Stand beside a living globe, move through time, follow narrated journeys, and inspect the maps, sources, and context behind each story.
Living globe
Grab, spin, scale, and inspect a polished Earth with source-backed layers and an immersive observatory stage.
Explore across time
Move the timeline to reveal routes, places, and historical context without treating uncertainty as certainty.
Living story arcs
Start a curated journey, pause on a beat, and inspect its route, narration, map, and sources together.
Historic map fold
See historical cartography as a source object first, then place it on the globe as an interpretive spatial layer.
Source cards
Every shipped map, route, story, and layer points back to a ledger, attribution, license posture, and known caveats.
Play to learn
Lightweight geography games reuse the same trusted spatial data instead of separate trivia.
How it works
Open Worldline Arc and enter a room-scale globe stage with the guide already present.
Choose Explore, Stories, or Play, then land on a place, route, map, or source-backed layer.
Ask what you are seeing. The guide answers from visible layers and source context instead of model memory.
Start a story, pause to inspect a beat, ask a question, and return to the same synchronized globe.
