Editorial Verdict
AI-researched, not hands-on testedObsidian's local-first, open-file-format model is genuinely rare -- notes stay private on your device, work offline, and the free tier has no artificial limits. The honest tradeoff: there's no built-in real-time collaboration or cloud sync (third-party setup or paid Obsidian Sync required), and the Electron-based app is noticeably resource-heavy.
