Capacities vs Tana

Capacities is a personal knowledge management app built around structured, typed objects (notes, people, projects, books, etc.) rather than a flat pile of documents. Users start from daily notes and create custom object types as needed, and the app automatically surfaces connections between related content instead of requiring manual backlinking for everything.

Tana is a networked note‑taking and knowledge‑management platform that lets users organize information as data using a powerful supertag system. Instead of flat documents, each note can be tagged, linked, and queried, turning personal knowledge into a searchable graph. The service runs in the cloud, offering real‑time collaboration, automatic syncing, and integrations that let you bring data from other tools into your Tana workspace. Its design focuses on turning ideas into actionable, structured information without forcing a rigid hierarchy.
