💡 Why we built Nexus Historia
Alternate history is not about replacing facts with fiction.
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.

💡 Bright idea
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.
@commutebuild I have been working on the following, and it is completed. Guided Classroom Timelines let teachers release evidence-led branches while students explore, reflect, and build private routes. Compare anonymised Student A/B/C outcomes and discuss how evidence shapes historical understanding.

How do Guided Classroom Timelines work?
Teachers create or select a Living Timeline, choose the historical lens, release branches as the lesson develops, and pin primary sources to key decisions.
Students join through their classroom code, explore the released history, then create a private route where they can make choices, add branches, and write reflections. Their work never changes the teacher’s master timeline.
Teachers can then compare anonymised Student A/B/C routes, identify where interpretations diverged, and lead a discussion about evidence, assumptions, causation, and consequences.

One shared history. Many reasoned routes.
