Capacities

Capacities is a personal knowledge management and note-taking app for individuals who want to capture ideas as connected objects instead of files in folders.

Key capabilities include:

• Object-based notes: create custom object types (for example, people, books, projects) with properties, templates, tags, and page layouts such as profile or encyclopedia.
• Linking and discovery: link anything to anything, view automatic backlinks, and surface unlinked mentions to reveal hidden connections across notes.
• AI assistance (Pro): an AI assistant for chat plus commands like summarize and translate, along with property auto-fill to help structure objects faster.
• Queries and automation (Pro): smart queries (object, search, tag), calendar integration that can create objects from events, task actions that send tasks to external managers, formulas in tables, and a public API (beta).

Pricing: Freemium (free tier available; Pro adds AI, queries, calendar, tasks, and more).

Notable for its offline mode, graph views for visualizing relationships, full export to standard formats, and integrations including Readwise, Kindle, Raycast, Web Highlights, and Zapier across Web, Desktop, iOS, and Android.
