What is Capacities?
Capacities is a modern note-taking and personal knowledge-management tool built around an object-based model. Instead of organizing everything into folders and flat documents, Capacities treats your notes as connected objects — people, books, ideas, projects, meetings — each with its own structure, that link together into a rich, navigable network. This object-centric approach makes it natural to build a structured "second brain" where information is organized by what it is and connected by how it relates, rather than buried in a folder hierarchy.
Its strengths are structure, connection and a thoughtful, pleasant design. By giving different kinds of content their own object types, Capacities helps you capture and find information in a way that mirrors how you actually think, and the linking between objects surfaces relationships and context as your knowledge base grows. It strikes a balance between flexibility and structure that appeals to people who want more organization than a simple notes app but find heavier tools overwhelming. The clean, focused experience makes building and revisiting your knowledge genuinely enjoyable.
Capacities is a great fit for students, researchers, writers and knowledge workers who want an organized, connected, object-based system for their notes and ideas — a structured second brain that is still approachable. It sits alongside tools like Notion, Obsidian, Tana and Reflect in the personal knowledge-management space, distinguished by its object-based model. If you have struggled to keep your notes organized and connected and want a tool that brings natural structure to your thinking, Capacities is a refreshing, well-designed option worth trying.
