Ask HN: How do you organize your list of academic papers?

I started reading a lot of research papers as of late, especially in Machine Learning. I keep a list of links to papers I want to read, or have already read, so I can easily get back to them.

I've been using Google Keep to do this:

- 1 note per topic (e.g.: Recurrent Models, Vision, Memory, etc), with checkbox enabled, and labelled "Papers"

- 1 link + paper name per checkbox item, marked as "done" if I've read it

This is not an ideal system, since it...

- breaks Keeps' search functionality (Keep highlights notes that match your search, not individual checkbox items)

- makes it very hard to reorganize items in separate notes (you have to copy-paste)

So I was wondering if y'all knew of a better way to organize academic papers. Is there a better tool out there I should look at? Is there a better way to use Keep? I've been suggested to use 1 note per paper, which also allows me to write down thoughts after reading the paper, but that also means cluttering my Keep with tons of notes and it becomes harder to organize papers by topic.
