Obsidian is the best knowledge management tool

everyone who collects lots and lots of information needs this knowledge management system. First all you do is download and go. No email no user name nothing. All files are stored locally (as simple text or markdown files) on your computer so you own and control all your data, Obsidian can disappear tomorrow and you can still access all your files and information. No subscription just download the software and you own it. Obsidian unlike things like notion has a graph view where you can see how all your ideas connect! It’s one of the coolest softwares I have downloaded in over a decade.
