Best reference manager for scientists

Paperpile today is simply the best reference manager for researchers, having used Mendeley, Papers, Zotero, and BibDesk in the past. All aspects of the experience and the app are polished and functional. Adding new papers, downloading PDFs automatically through your university proxy, annotating / highlighting, and organizing your library all work seamlessly. The citation experience in google docs is excellent even with many users even when not sharing the same paper library. The latex experience via Overleaf could be improved a bit with some kind of automatic BibTex export, but overall it’s better than any of the alternatives. Highly recommended.

Developer Response ,

Thanks, regarding Overleaf and BibTeX export. I hope we have some announcements about this soon 😀. In the meantime, we have put together a short survey on these topics to better understand our users' workflows and use cases:

Best reference manager + editor

Have you struggled deciding between Zotero, Mendeley, Endnote on the one hand, and Adobe Reader, Notability, LiquidText on the other? Have you wished there was an app that allowed for the editing flexibility of the latter apps, while retaining an organized version of your literature review? Well... look no further. This app is just excellent. Ever since I discovered it, I immediately jumped into the beta version and it has been a blast. I’m so happy to see it now open for everyone else.

I would recommend to everyone who is into academia or research. Amazing!

Love Paperpile though slightly frustrated with the iPad app

Have loved Paperpile ever since I’ve been in undergrad; it has been my go to reference manager and pdf annotator for years! I was so excited to see the app come to iOS, though I am seeing some issues with going back and forth from the iPad version and the web version. My annotations do not sync properly between the two. Paragraphs I highlighted on one are in complete different places on the other! Makes taking notes a little difficult. Hopefully this problem will be fixed soon, but I am so excited to see the app grow, and would recommend it to anyone !
