Capacities Review

Worth it

Should I use Capacities?

Capacities is a note-taking and knowledge management app that organizes your ideas as connected objects instead of files and folders. Available free on Mac, Windows, Linux, iOS, and Android. - capacities.io

· 1 month ago

Individuals who want object-based, connected notes should start with the free plan — it is low-risk and well reviewed. Teams, enterprises, and anyone needing end-to-end encryption should look elsewhere.
