Notion and Obsidian are two of the most popular note-taking apps, but they approach knowledge management very differently. Notion is an all-in-one workspace with databases and project management, while Obsidian focuses on plain-text Markdown files and a powerful graph-based linking system. Which one is right for you? Let's find out.

Choose Obsidian if you prioritize local-first, plain-text notes, long-term data portability, and the most powerful backlinking system available. For most knowledge workers, Obsidian wins on longevity; for teams, Notion is hard to beat.
