Capacities

About

Capacities is a Mac app for capturing and organizing everything you think, learn, and create. Instead of filing notes into folders, it turns people, books, projects, and ideas into objects that you can link to one another, so your knowledge forms a connected network you can navigate as you think.

The app is built around a daily note that serves as an inbox, letting you capture thoughts without deciding where they belong first. Backlinks show every connection to an object at a glance, and Related Content scans your notes to surface places where you wrote about something without linking it, helping connections you already made come to light.

Capacities emphasizes simplicity: according to the site, there is no configuration, no markdown syntax to memorize, and no plugin setup, so you can open the app and start writing. The site also highlights a free tier and a Pro plan offered at a student discount.
