QOwnNotes is the open source (GPL) plain-text file markdown note taking application for GNU/Linux, Mac OS X and Windows by Patrizio Bekerle (pbek on GitHub and IRC), that (optionally) works together with the notes application of ownCloud or Nextcloud.
You are able to write down your thoughts with QOwnNotes and edit or search for them later from your mobile device (like with CloudNotes) or the ownCloud / Nextcloud web-services.
The notes are stored as plain text files and you can sync them with your ownCloud or Nextcloud sync client. Of course other software, like Dropbox, Syncthing, Seafile or BitTorrent Sync can be used too.
I like the concept of having notes accessible in plain text files, like it is done in the Nextcloud notes app, to gain a maximum of freedom, but I was not able to find a decent desktop note taking tool or a text editor, that handles them well in conjunction with ownCloud or Nextcloud.
Out of this need QOwnNotes was born.
