Our verdict
Obsidian's promise is simple: your notes are local Markdown files and will still open in twenty years. On top of that sit more than two thousand community plugins, enough to assemble boards, calendars, paper management and even a small CRM. The price is tinkering — and real collaboration depends on third-party sync.
ข้อดี
- Data is entirely yours, plain Markdown with no lock-in
- The plugin ecosystem has almost no ceiling
- Works offline and opens instantly
ข้อเสีย
- No real-time collaboration out of the box
- Plugin quality varies and over-tinkering is easy
- Mobile sync needs a paid plan or self-hosting
