Graph view

See the whole library at once.

Graph view maps every note and the links between them. It is the wide shot: the place where you notice you have written about the same thing five times in three different folders.
Every linked note plotted across the whole library
Spot clusters you never filed together
Jump straight from the graph into a note
Note stats alongside it for how your writing is spread out
Connections you did not plan
Two notes from different months turn out to be about the same thing.
Links do the work
Link note to note as you write and the map fills itself in.
Where your attention went
Note stats show what you have actually been writing about.

Your Notes Are Worth More Than You Are Getting Out of Them

Download Grape, point it at a folder, and see what one week of notes looks like when you can ask them questions.
