Checks a paywalled article's DOI for a legal free copy posted by the author or publisher, usually through a browser extension.
Before you rely on itIt finds only copies the author or publisher has legally made free, so many paywalled articles return nothing, and installing the extension asks for an email address.
Install it once and it quietly tells you when a paywalled article you are reading has an authorised free version elsewhere.Telebem editors
