Capacities
Capacities is a connected note-taking and personal knowledge management app for linking ideas, tasks, media, and structured objects.
Capacities lets people capture daily notes, create structured objects such as books, projects, and meetings, link related content, and browse their knowledge graph. It includes block-based editing, templates, multiple views, media embeds, search, and integrations for capturing content and managing tasks.
Pro adds AI assistance, smart queries, calendar integrations, task management, media analysis, version history, and API access. The product is designed for individuals rather than teams and does not provide real-time collaboration. Heavy AI use may require the optional Plus add-on or top-ups.
