What Users Say About Obsidian
Obsidian is the favorite of researchers, PKM obsessives, and writers who want local-first control over their notes. Users consistently praise the 2,000+ community plugins, the backlinks/graph view, and that the app is 100% free for personal use (including commercial). The complaints cluster around the collaboration story (not designed for it) and the initial setup friction — you're essentially assembling your own note-taking app from plugins.
Highlights
- 100% free for personal AND commercial use — no feature gates for solo users
- 2,000+ community plugins mean almost any workflow is buildable
- Markdown files on your disk — no lock-in, editable with any text editor
- Graph view and backlinks are best-in-class for idea-heavy knowledge work
- Optional Sync ($5/mo) and Publish ($10/mo) stay honest add-ons, not feature gates
Limitations
- Not built for team collaboration — concurrent editing and sharing are weak
- Initial setup requires choosing plugins, themes, and folder structures — blank-canvas fatigue
- Mobile app is capable but less polished than Apple Notes or Bear
- Web clipper is community-built rather than first-party
- No native AI features — everything AI flows through plugins with your own API keys
Best for: Researchers, writers, and knowledge workers who want full ownership of their notes in plain files, and who enjoy customizing their tools. The right pick for anyone who has outgrown Apple Notes/Evernote and wants a PKM system that will still be readable in 20 years.
