The king of PKMs. Where all my writing, clippings from all the resources, thoughts, planning, projects, daily journals live. Has all the aspects of a sustainable and enjoyable software model IMHO:
- majority of features free for life
- a sustainable business model beyond that
- a vital and passionate plugin developer and enthusiast community
- your data locally stored in plain text with no compromise in all the fancy features that competitors offer but instead lock your data in a database or cloud storage.
