I think it’s trying to be a markdown-based Obsidian/Logseq zettelkasten with built-in support for (1) interfacing with reference managers and (2) exporting/publishing with LaTeX/pandoc.

If you want to see it and get an idea about what it does and how it’s supposed to be used, go here:

Finding that information took some digging — although there is a visual on the homepage after scrolling several screens down (at least on mobile).

Constructive feedback for the team: I find the website and documentation difficult to use because they present details first and main ideas later. See if you can put the bottom line on the top line.

Also, as I navigated through the site, every time I followed a link I got asked, again and again, whether I wanted to opt out of cookies and data collection. Answering once should be enough.
