Ask HN: Does a genius.com-like app to annotate ArXiv papers exist?
I believe the "Librarian" Chrome extension - https://fermatslibrary.com/librarian - from Fermat's Library should do that, but I'm not certain if the comments are shared across users.
If you download the PDF, you can annotate PDFs locally. Why not do it that way?
It's about the crowd-sourcing aspect of genius.com.
Experts in the various fields could annotate papers in order to make it easier for non-science-savvy people to get what is going on.
This is an interesting idea. I think the problem with such an app is that reviewers and publishers have sort of a monopoly on papers, which makes it hard from a business perspective
