Hi, I have just open-sourced my take at a personal knowledge management system. There is also a free-to-use hosted version.
It is a web-based system, with the following features:
- typed relationships
- outline view
- easy picture upload
- private by default
- simple journaling
- publishing to reveal.js
- import from Evernote
After importing my Evernote notes I have started to use it on a daily basis. The UI is nothing fancy, but quite usable due to an integrated markdown editor.
If you are looking for a note taking app, why not give it a try and tell me what you think.
