I love all these Roam Research style tools--always felt this was a really cool idea.

If anyone is interested in open source options, I'd recommend:

Foam - A Roam-inspired tool for markdown note taking--ahem, personal knowledge management (same features as Organizedly)--that runs on VSCode/Codium. I personally use and love it. Syncs across all my devices with Git, and deploys easily on free-tier Vercel, which is a nice way to check my agenda or read a note on my phone. https://foambubble.github.io/foam/

org-roam, for those emacs/org-mode people. I always wish I had the fortitude to become productive in emacs, but it seems it never will happen. https://github.com/org-roam/org-roam
