Reviewers largely praise Capacities for its object-based approach, saying it hits a rare balance between structure and flexibility for notes, bookmarks, journaling, research, and project tracking. Many prefer it to Notion, Obsidian, Roam, or Logseq because the UI feels cleaner, faster, and easier to work in, especially for linking information without heavy setup. The main caveats are a learning curve, limited offline support for some users, missing power-user features like deeper customization or imports, and concern that paid plans may be expensive.
