What is Capacities?
Capacities is a personal knowledge management tool designed to help individuals capture, organize, and connect their thoughts and ideas in a natural, intuitive way. Built by a user-focused team funded by its community rather than venture capital, it addresses the problem of scattered notes and lost insights by turning everything you care about—people, books, projects, ideas—into structured, linked objects. Unlike traditional file and folder systems, Capacities creates a living network of your knowledge, allowing you to link anything to anything and discover connections automatically. Its core capabilities include daily notes as an inbox, object creation with customizable types, backlinking, and automatic related content suggestions. It fits knowledge workers such as writers, researchers, students, developers, and founders who want a distraction-free, powerful space to think and create without complex setup or overwhelming customization.
