It is a way to understand why real events mattered. By changing one decision and following the consequences, users practise: Critical thinking Cause-and-effect reasoning Evidence evaluation Historical interpretation Decision-making Creative and analytical writing We are building a place where historical accuracy and imagination can exist together—without confusing one for the other.

A classroom mode where teachers can lock certain timeline branches and pin primary source documents to specific decision points would make this way more useful for history lessons. Right now it feels more like a personal exploration tool, but that one feature could really open it up to actual curriculum use.
