The Real Difference
Both offer free tiers, so the real question is what you get when you start paying.
Obsidian stands out with Local-first markdown files and Bidirectional linking. Tana counters with Supertag-based schema system and Live search nodes.
Obsidian's Achilles heel: no real-time collaboration — syncing across devices requires paid add-on or diy solution. Tana's: steep learning cliff — the supertag concept is powerful but takes days to grok properly. Pick whichever weakness you can live with.
Bottom Line
If you value local-first markdown files and power users and developers, go with Obsidian. If power users who want matters more, Tana is your pick. Neither is a bad choice — but one will fit your workflow better.
