Open Access Helper now brings a new type of Safari Extension to your Mac, which will signal the availability of an Open Access version of a paywalled scientific article!

Open Access Helper brings the power of and to your iPhone and iPad as an intuitive Safari Extension. 

Skip the publisher paywall for more than 30 million Open Access documents and unlock the power of your academic library with additional services, such as EZProxy-Linking and quick access to the library's link resolver.

If you like you can enable citation counts from and Open Access recommendations from

Additionally the app offers the ability to search for Open Access documents within the massive and collection, making academic research just that little bit easier.

Things you should know:

Open Access Helper works best, if you give it permissions to access all websites, so it can identify the Digital Object Identifier (DOI) of an article and query and/or for an Open Access copy for you. A small badge in the top right of the page will indicate whether an Open Access copy is available.

The EZProxy prefix for several hundred academic libraries worldwide can be added to the popover. EZProxy helps you gain remote access, but you will require a user-id and password from your library.

Lastly, Open Access Helper is my passion project. I am not affiliated with any of the services and / or libraries, who have so generously provided their APIs.
