本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Logseq stands out with Outliner-based note-taking and Bidirectional linking. Mem counters with AI-powered search and organization and Automatic note connections.
Logseq's Achilles heel: outliner-only format is polarizing — if you want freeform docs like notion, this will frustrate you. Mem's: ai magic is hit-or-miss — sometimes surfaces gold, sometimes nonsense, and you lose control over structure. Pick whichever weakness you can live with.
結論
If you value outliner-based note-taking and サブスク不要でroamスタイルの双方向リンクが欲しいプライバシー重視の思考家, go with Logseq. If 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 matters more, Mem is your pick. Neither is a bad choice — but one will fit your workflow better.
