Capacities
Notes as objects — people, books, projects — linked into a network that mirrors how you think.
Standout features
Capacities treats every note as an object — a person, a book, a meeting — with its own type and properties, not just a page.

- AI and integrations sit behind Pro.

Capacities resonates with people who never gelled with folders — they like notes as typed objects and say the app feels faster and cleaner than Notion. The free tier is praised as unusually generous. The common caveats: AI and integrations sit behind Pro, the object model takes a beat to learn, and mobile lags desktop. For object-minded PKM, sentiment is positive.
Capacities is built by Capacities Labs GmbH, a German studio behind the object-based knowledge app.
