Roam Research is a newly developing tool created by Conor White-Sullivan that focuses on creating a graph of notes instead of the traditional hierarchical system of most note-taking systems.
However, it is closed source and (thankfully) open source alternatives like [[https://github.com/jethrokuan/org-roam][Org-roam]], [[https://github.com/andjar/dokuroam/][Dokuroam]], and [[https://github.com/athensresearch/athens][Athens]] started to fill our Roam-voided hearts.
