Well... I have mine in Emacs/org-mode/org-roam managed notes, integrated being in a single integrated platform with no need of extra code, with my mails (notmuch), contacts (org-contacts), financial transactions (beancount), file (org-attach-ed) etc down to the infra/OS config (NixOS tangled from org-mode, org-babel blocks, as per the Emacs, zsh, mplayer, ... configs). The point is that with classic tools IS EASY, limited only by the current sorry state of IT things, with modern tools is a nightmare that demand much effort to be done.
