Short description
Zim is a graphical text editor and personal wiki that can be used as a personal knowledge base or notebook. Pages are stored locally in a folder structure in plaintext. Zim is available on Linux, macOS, and Windows.
Why I think this tool should be added
Privacy Guides currently doesn’t recommend any local knowledge base tools except Org-mode for Emacs which isn’t really ideal for non-programmers or anyone who doesn’t use Emacs. Zim is fully graphical and user-friendly but is still lightweight and doesn’t use Electron (all of the recommended cloud-based notebooks with desktop apps do).
Zim is open source and supports exporting documents into HTML, Markdown, and other formats. The rest of the criteria doesn’t apply since Zim doesn’t support cloud sync.
Although some of the cloud-based notebooks PG currently recommends may work offline, I still think offline-only notebooks should be recommended for those who prefer not to have cloud sync at all. As aformentioned, all of the cloud recommendations either use Electron or are web-only and there are plenty of reasons to avoid Electron like security issues and bloat issues.
