    and this is the best theme imo

    Another cool opensource note taking app that I can highly recommend is cherrytree.

    Athens is a knowledge graph for research and notetaking. Athens is open-source, private, extensible, and community-driven.

    Athens is a similar tool, and it is open source: https://github.com/athensresearch/athens
