Capacities replaces the traditional file-and-folder model with an object-based approach: people, books, projects, and ideas each become structured, interconnected entities. Daily notes serve as a frictionless inbox, while automatic backlinks and related-content surfacing help you rediscover connections you didn't know you'd made. Trusted by 50,000+ knowledge workers, it aims to mirror how the brain actually works rather than how computers were designed in 1984.
Best for: Knowledge workers, researchers, writers, and note-taking enthusiasts who want a connected, object-based PKM without heavy configuration

Pros
- Genuinely novel object-based paradigm reduces folder-filing overhead

Cons
- Advanced features like AI and calendar are locked behind the paid Pro plan, which may feel expensive for casual users
- Less mature and feature-complete than established competitors like Obsidian or Notion (e.g., no community plugin ecosystem)
- No true offline-first local storage — data is cloud-hosted, which is a dealbreaker for privacy-focused users
- Object model has a learning curve for users accustomed to traditional folder hierarchies
- Mobile app experience lags behind the desktop/web version in functionality
- Smaller template and integration library compared to Notion or Obsidian
