tzk (TiddlyZettelKasten) is a TiddlyWiki edition and associated CLI for maintaining personal notes in something approaching the Zettelkasten method. It’s updated periodically from whatever tooling I’m currently using in my own Zettelkasten. As such, it’s currently considered alpha-quality; while it ought to be very stable and there’s no meaningful risk of data loss, updating to a newer version might be difficult and I’m unlikely to accept patches unless they’re something I want in my own Zettelkasten. This is intended primarily as a nice starting platform on which to build your own tooling.
Some basic knowledge of TiddlyWiki is necessary and assumed.
Find a live version of the edition on the web with further instructions at https://sobjornstad.github.io/tzk/. You can find the documentation for the CLI (which handles creating the wiki, versioning with Git, and creating public and other derivative versions of the wiki) at https://tzk.readthedocs.io/en/latest/.
Since tzk is still in an alpha state, general instructions on how to use it are somewhat lacking at the moment. To fill in the gap in the meantime, I recorded an hour-long walkthrough showing how you might take notes using tzk; you can select individual sections to watch if that's longer than you want. Watch the video on YouTube.
