FIND OPEN ACCESS, LEGALLY AND WITH PRIVACY IN MIND

What comes to mind when you hear “Open Access”? Free! No paywalls! That’s right. But accessing free content can be complicated, with confusing terminology and various access points.

Open Access Helper simplifies this process. When it encounters a DOI, it queries the APIs of unpaywall.org and core.ac.uk to find available Open Access copies.

The app is free and it will always stay that way.

Your privacy is important. If you have any questions, don’t hesitate to reach out!
