Open Access Helper uses the trusted APIs from unpaywall.org and other sources to locate open access copies, making research more accessible for students, researchers, and curious minds. How It Works When you view a research article, the extension detects its DOI (Digital Object Identifier) and checks for an available open access version. Simply click the Open Access Helper badge to access the document!
