I tried tons of personal knowledge management apps and eventually settled with Logseq. It’s incredible if you’re more of an outliner, the workflow just fits me like a glove. I just dump everything into daily journals and let the connections arise from there as I go.
My one big complaint is you can’t self host a self contained web version of it (meaning you still have to open a local working folder even if you do host your own, which defeats the purpose imo), which then forces you to either sync between devices manually or use their paid service. Since there are Windows and Android apps I make do with Syncthing, but it’s unnecessarily clunky.
