I wanted something with the ease of notepad, the structure of evernote, and the speed of redis.
Iterating over these features led me to Dendron and its been battle tested with my own collection of 30K+ notes
Obsidian (and other tools like it) focus on backlinks and using a graph to connect your ideas. This is valuable for connecting disparate ideas but its still hard to find any individual note once you have a lot of them.
Dendron helps you organize your notes into hierarchies that you can enforce using schemas (think type system but for your hierarchies)
The problem we're solving: once you have hundreds or thousands of notes, how do you find a specific one?
