FAQ

Is Capacities free to use?

Yes, Capacities offers a free 'Basic' plan with unlimited spaces, objects, and blocks, synchronization across devices, custom object types, and full import/export support. The core product will remain free forever.

How does Capacities compare to other note-taking tools like Notion or Obsidian?

Capacities differentiates itself by focusing on 'object-oriented' thinking, where everything is an interconnected object with its own structure, rather than files in folders. While it offers powerful linking like Obsidian, it aims for a more curated experience than Notion, with less emphasis on endless customization and team collaboration, and more on individual knowledge management.

What kind of AI features does Capacities Pro offer?

Capacities Pro includes AI integration that allows you to chat with any note, auto-fill properties for objects (e.g., author, genre for a book), and use smart commands like summarizing or translating text. The AI is contextual and grounded in your notes.
