I was thinking about #Obsidian, a growing knowledge base and linking. In the beginning, as you make notes on a topic, you don't make links because you don't know the facts are related yet. It would be cool, and maybe a good use of AI, if there were a tool that could go back and link all your notes and build the knowledge graph. Think of one of those boards in detective shows where they just start pinning facts to the board. Victim, crime scene, suspect 1 then some clue is revealed and everything links up and you have a case.
