History books cover one place at a time, so comparing places is hard. Chronarium gives each place, person or theme its own lane, stacked over the same years, so you can compare Rome and Han China at a glance. Mac app, or Chrome or Edge, no install.

I've always liked rereading my old history textbooks. What I wanted was to see events and periods laid out in space, and timelines do that well. The trouble is one timeline turns into a mess the moment you compare two places or periods, like Rome and Han China.
Three things it does differently. Every place, theme or person gets a lane, and all lanes share one time axis, so contemporary events line up. You can zoom from centuries down to a single year. And any event opens into a concept map of its people, causes and consequences. Closing the map puts you back at the same spot in time.
There is a free trial with no card. After that it is $39 per year, or $79 once for a lifetime licence. You can try it in Chrome or Edge with nothing to install. One licence covers both.
How do you keep track of history or timelines today?
