Anki's interface really discourages me from using it. Quizlet seems like a much better alternative (though spaced repetition requires a subscription).

A while back I was looking for something that would index my external hard drives so I could browse them and view file metadata. None of the options seemed appealing.

I really want a personal, locally-hosted wiki that lets me write in Markdown, keep revision history, link between documents, and attach files. Having inline-executable code like Jupyter would be cool also. I've bought a few versions of VoodooPad only to be disappointed by how basic it is.
