QOwnNotes is the open source (GPL) plain-text file notepad with markdown support and todo list manager 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 own your own notes! All notes are stored as plain-text files on your desktop computer.
- Sync them over devices (desktop & mobile) with your ownCloud or Nextcloud sync client.
- Use ownCloud Notes to edit your notes in the web.
So 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.
