Object-based notes for building a personal knowledge base
Capacities is a note-taking app that organizes knowledge as objects such as people, books, meetings and ideas, each with its own properties and templates, instead of folders. Objects link to each other through backlinks and a graph, daily notes collect everyday thoughts, and the Pro plan adds an AI assistant. It is developed by a small team in Germany.
