Cool, reminds me of "Roam Research" which calls itself a tool for "networked thought" [1]
Implementing the Zettelkasten is an explicit use-case for Roam, as documented here: https://roamresearch.com/#/v8/help/page/VURQiVZQR
There are these two articles that can show new users what this app is about:
- https://www.nateliason.com/blog/roam
- https://www.reddit.com/r/RoamResearch/comments/eho7de/buildi...
There is also https://www.remnote.io/ , but it's too complex and clunky right now, at least for me.
