Many note-taking apps can mimic the functionality of the Zettelkasten system but have certain limitations like few backup options, and loss of insight links in case of a shutdown of the app. Others offer pristine functionality of the idea filing and linking system but have the same proprietary and database concerns.
The best way is to go manual and build a word file using hypertext links, notes, and references.
One can try a mix-and-match approach, making sure that one is able to:
- quickly start a new idea or note.
- quickly link two or more notes.
- able to retrieve a note easily.
- is synced and is usable in multiple devices.
