I was lucky to get desktop access but behind the usual reference management tools (citations, adding PDF’s and highlights), I don’t find anything else. I can’t extract annotations, no Dropbox integration and costs $5 per month. Will you pay for it?
I am not convinced although, I still feel that it has potential. I like the recommendation engine- which suggests equivalent papers.
I am also planning to work with the Refden developers and see how it goes.
It’s accessible here.
