    Zim is more like simplenote, or a desktop wiki. It is missing most of the functionality of onenote.

    Markor is light, fast and uses Markdown text so your notes can be read on all devices. With OneNote you need the app to open your notes.

    Open-source, feature-filled and uses open formats so it is future-proof. Actively updated with new features. A great app for notes, to-do lists and jotting down thoughts and ideas.
