Overview
Product summary
Review the store description, core capabilities, and common use cases.
Get full text of scholarly articles as you browse. When you view a research article, Unpaywall automatically looks for a copy in our index of 20 million free, legal fulltext PDFs. If we find one, click the green tab to read the article.
Unpaywall points you to legal, author-posted manuscripts that are hosted on university and government web servers. We are pointing to versions that have been posted with the full and explicit authorization of the publishers themselves.
These free, author-posted manuscripts are often called "Green Open Access" and are a longstanding and completely legal part of the scholarly communications ecosystem. The majority of scholarly journals permit authors to "self-archive" their papers on university and government web servers. It's these legally self-archived papers that Unpaywall helps users find. Any papers posted outside of publisher permissions are NOT included in our index.

i like i like you guys will love it bypass ai feature
it doesnt work.IDK
Literally saving my college career with the way I can actually access articles that are vital to my assignments and schoolwork without having to pay for it or go through ten pages to "sign in through my institution" just for it not to work.
Reading research papers for free is very user-friendly.
The best.
journals/studies behind an actual paywall are not free to access with this extension. The papers that show up with a green lock with this extension are already free and open access. Tried over 20 papers across several different providers. This extension acts like a download button for ALREADY open access and free papers and does not bypass a paywall. Not sure what the point of this extension is!
Doesn't work. Shows the green lock, but clicking on it does nothing, just asks for an account to that publisher's platform. Now if I had that we wouldn't be here would we.
Nou, die werkt niet hoor !
No sirve de nada. Pongo una estrella porque no deja poner ninguna, si no, ni eso.
Great app for downloading paper.
