I can't do without Obsidian now. Its default graph representation of knowledge matches how my scatterbrain works. It has the creature comforts I've come to expect: simple (local) text storage, a fast command/search palette, gobs of integrations (e.g. Excalidraw for my tablet). Watching one of my knowledge vaults evolve is incredibly satisfying.[1]
Obsidian is the only note app that I've stuck with. Notion/Apple Notes/Goodnotes/etc just had excessive pain points. Obsidian "just works" for my brain. Which is a relief, since the productivity app treadmill is exhausting.
