About Capacities

Capacities is a modern note-taking and knowledge management app built around the concept of 'object types' — instead of just documents and folders, you create Books, People, Topics, Projects, and custom types that have their own properties and views. This makes Capacities feel more like a personal database than a note app. The Daily Note feature keeps a running journal while all notes connect through typed relationships. Capacities AI can draft, summarize, and extract structured information across your notes. Its clean interface and focus on reducing friction makes it popular among people who find Notion too heavy and Obsidian too technical.
