Everything was happening at the same time
While Napoleon conquered Europe, the Qing Dynasty was at its peak, and the United States was just 20 years old. Eras is the first tool that makes that visible.
Click any event. See the whole world
at that moment.
We learn history as isolated chapters — Ancient Greece, Imperial China, Colonial America. But these happened simultaneously. Eras puts them on the same map, at the same time, for the first time.
10,000 Athenian soldiers defeat a Persian force twice their size, preserving Western civilisation at its most fragile moment.

History as it actually happened —
simultaneously, globally, causally
Simultaneity
See what was happening across the world at exactly the same moment. While Rome burned, Han China was inventing paper. Eras makes that visible.
Living Map
Borders shift as you move through time. Constantinople becomes Istanbul. Persia becomes Iran. The map reflects the world as it actually was.
Three Depths
A curated snapshot. A Wikipedia extract. An AI-generated narrative. Go as deep as your curiosity takes you, at your own pace.
Causal Threads
SOONSee how events caused other events across decades. The Fall of Constantinople triggered the Renaissance. History is a web, not a line.
People Timelines
SOONFollow a historical figure across their entire life. See every event Napoleon touched, from Corsica to Saint Helena, plotted across the world.
Quests
Guided journeys through history. The Rise of Islam. The Age of Exploration. The Road to WW1. Learn through narrative, not memorisation.
