Mem vs Notion——どっちが優秀？
Memを選ぶべき人: 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
Notionを選ぶべき人: ドキュメント、Wiki、プロジェクト管理を1つのツールにまとめたいチーム向け
私たちの見解: Mem is easier to pick up, but Notion is more powerful long-term.
| Mem | Notion | |
|---|---|---|
| 料金 | Free tier with limited AI | Mem Plus $14.99/mo | Free personal plan | Plus $8/user/mo |
| 機能 | AI-powered search and organization, Automatic note connections, Smart collections, Meeting note capture, Chat with your notes | All-in-one workspace, Database views, Team wikis, API & integrations, AI assistant built-in |
| こんな人に最適 | People who hate organizing notes manually and want AI to surface the right information automatically | Teams that want docs, wikis, and project tracking in one tool |
| 学習コスト | 簡単 | 普通 |
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. Notion counters with All-in-one workspace and Database views.
Mem's Achilles heel: ai magic is hit-or-miss — sometimes surfaces gold, sometimes nonsense, and you lose control over structure. Notion's: gets slow with large databases and complex setups. 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 ドキュメント、wiki、プロジェクト管理を1つのツールにまとめたいチーム向け matters more, Notion is your pick. Neither is a bad choice — but one will fit your workflow better.
