LogSeq stands for Logical Sequence. They pride themselves on their journaling feature which offers the same STRUCTURE of infinitely-nested notes.
If you want to test drive a free SaaS alternative that works similarly- try WorkFlowy. You can use a burner email and not provide payment info.
The concept of these apps is nested information. Everything is stored within individual nodes. This means your lists grow over time, and can evolve into multiple lists. This is organic information management, the same way our brains work naturally.
I do not use journaling at all myself. The base features of the app, creating new "pages" and entire graphs which contain my SPECIFIED data, is the value. LogSeq allows us to actually manage the notes we store.
On the note of journaling- I actually use a hacky workaround to replace the journal button with an "index" button which functions as a table of contents for the graph I am working within. This is pretty much what I consider the optimal note-taking environment that users are looking for. And there are plenty of drawbacks in using LogSeq and this workaround. We know the experience can be better one day, but LogSeq is king for now.
