RavenDOI was born from the desire to help those who believe that knowledge should be accessible to all without restrictions. RavenDOI will speed up your search for scientific articles by transforming the DOIs (scientific article numbers) on your page into clickable links to the articles in question on the site you have indicated in the extension like https://sci-hub.tw for example. To activate this extension on the site you are on, simply open the extension and click on the switch button. In your extension bar, you can see the RavenDOI ON/OFF badge that tells you if the site you are on is activated. This extension is open-source and free of charge. It contains no analysis tools and only stores information as part of its use and only in your browser. We invite you to contribute to RavenDOI and the other projects available on our website.
