Capacities

Capacities is a networked note-taking tool built to help you capture ideas, connect them, and turn scattered thoughts into a coherent knowledge system. Think of it as a “studio for your mind”: a calm, focused space where notes aren’t just stored, but related to each other so your thinking can evolve over time. Instead of keeping information in isolated pages, Capacities encourages you to build a living web of concepts—useful for learning, research, creative work, and day-to-day planning.

You can write quick notes or longer documents, then add structure with tags, links, and contextual backlinks that show how one idea references another. Block linking lets you reference a specific paragraph or section, making it easy to reuse snippets across projects without duplicating content. Capacities also supports custom object types with properties, which is helpful if you want your notes to behave more like a database—e.g., tracking books with fields for author and status, meetings with attendees and outcomes, or projects with milestones.

Getting started is straightforward: create a free account, begin writing, and gradually connect your content as patterns emerge. Daily notes can be used to plan and reflect, while calendar integration helps tie your tasks and sessions to real time. On mobile, you can search your knowledge base, upload content, and take notes wherever you are, so your system stays accessible and up to date. more
