Notes & Knowledge
Personal and team knowledge bases.
Every note app is pleasant for a month. The question is what happens in year three — whether your notes are plain files you can open with anything, or rows in a database only one company can read. Structure is the second axis: Notion wants you to model your work, Obsidian just wants a folder.
Editor's pick
Obsidian if you expect the notes to outlive the app. Markdown files in a folder you control, and the exit costs you nothing.
