Capacities.io

verifiedFreemium

Object-based note-taking and personal knowledge tool that links everything as connected objects instead of files and folders.

What it does

Capacities is a note-taking and personal knowledge management app that treats everything you capture as an 'object'-a person, book, project, or idea-with structure and properties. Objects link to each other to form a connected network, with daily notes as an inbox and AI-surfaced related content. It emphasizes no lock-in, full export, and EU-hosted, GDPR-compliant storage.

How to use: Start by creating a free account. Use the app to type notes, tag content with keywords, link to individual blocks, and connect your calendar. The mobile app allows you to search, upload, and take notes on the go.
