本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Mem stands out with AI-powered search and organization and Automatic note connections. Tana counters with Supertag-based schema system and Live search nodes.
Mem's Achilles heel: ai magic is hit-or-miss — sometimes surfaces gold, sometimes nonsense, and you lose control over structure. Tana's: steep learning cliff — the supertag concept is powerful but takes days to grok properly. Pick whichever weakness you can live with.
結論
If you value ai-powered search and organization and ノートを手動で整理するのが嫌いで、aiに自動で適切な情報を出してほしい人, go with Mem. If 構造化された検索可能なノートで、自分だけのパーソナルosを構築したいパワーユーザー matters more, Tana is your pick. Neither is a bad choice — but one will fit your workflow better.
