本当の違い
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 Plugin ecosystem (1000+). Roam Research counters with Block-level references and Daily notes workflow.
Obsidian's Achilles heel: no real-time collaboration — syncing across devices requires paid add-on or diy solution. Roam Research's: no free plan, web-only (no native desktop), and the community has shrunk as obsidian and logseq grew. 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 つながったアイデアで思考し、ブロックレベルのリンキングが欲しい研究者やライター向け matters more, Roam Research is your pick. Neither is a bad choice — but one will fit your workflow better.
