My brother is a historian, this sounds like something he would love using and maybe even contributing given his extensive knowledge! Let me know if you are looking for someone knowledgeable
It's really interesting application ! My brother really enjoying it. Can't wait to see the next version of it. One suggestion if you can add persona for hard maths and science formula, so that they can talk to it. and they tell their story that how they form. Just like we tell our growth story from childhood to till now.
