Open Access Helper

 This browser extension helps you find an open-access version of a scientific article.

The Open Access Helper extension works on the same principle as Unpaywall, and uses its API.

In addition, you can extend the possibilities of the extension by activating, via the settings, CORE Open Access and/or the Open Access Button.

Open Access Helper is compatible with Safari, Chrome, Edge and Brave.
