Hello guys, I'm looking for a program to help me study, but I don't know if what I need exists or not, so I thought I'd ask you. I would like to have a program that allows to create encyclopedia entries from scratch. Or something like that. That is, I am not interested in downloading an offline version of an existing encyclopedia, such as Wikipedia, etc. What I would like is to be able to add entries to help me categorize and memorize each content already studied. Is there anything similar for linux?
