Quillnote is a free note taking developed by a Comp. Sci student at the University of Thessaly. It's fast, easy to use, and has tons of functionality including audio recording, markdown support, tags, and image attachments. Best of all it's Open-Source (GPL-3.0) and supports synchronization with Nextcloud (experimental)! On the downside search is fairly basic and hidden in a menu.
