Direct answer
What is Capacities?
Capacities is an object-oriented note-taking and personal knowledge management tool that replaces rigid folder hierarchies with connected objects, daily notes, backlinks, and AI assistance.
Capacities offers a personal knowledge management workspace centered around 'objects' rather than traditional files and nested folders. Users define structured object types—such as projects, books, people, meetings, or ideas—each holding distinct properties while remaining linkable to any other piece of information. The workflow emphasizes frictionless daily note-taking as an intake stream, from which thoughts and tasks are converted into structured objects. The platform includes networked note-taking capabilities such as bidirectional linking, automatic related-content detection, smart queries, and calendar integrations. For professional and intensive use cases, Capacities provides integrated AI workflows, including contextual AI chat with your notes, AI autofill for object properties, and media analysis. All core personal features—such as device synchronization, custom object types, offline support, and full data export—remain available in the free version.
Unlike standard document editors or folder-based note tools, Capacities organizes information around typed objects with defined properties and surfaces unlinked connections automatically across your workspace.
