本当の違い
Obsidian offers a free tier while Reflect doesn't — that matters if you're bootstrapping.
Obsidian stands out with Local-first markdown files and Bidirectional linking. Reflect counters with End-to-end encrypted notes synced across devices and AI assistant for summarizing, rewriting, and organizing.
Obsidian's Achilles heel: no real-time collaboration — syncing across devices requires paid add-on or diy solution. Reflect's: no free tier whatsoever — $10/mo is steep when obsidian does backlinks for free with local files. Pick whichever weakness you can live with.
結論
If you value local-first markdown files and 自分のデータを自分で持ちたい、パーソナルなナレッジグラフを作りたいパワーユーザーや開発者向け, go with Obsidian. If 暗号化やスピードを犠牲にせずroamスタイルのネットワーク型ノートが欲しいプライバシー重視の思考家 matters more, Reflect is your pick. Neither is a bad choice — but one will fit your workflow better.
