Automatic Article Access
EndNote Click uses artificial intelligence to detect the user’s institutional or individual subscriptions, allowing instant access to journal articles with just one click. This feature saves researchers significant time and frustration by automatically identifying and leveraging existing subscriptions.
Open Access Alternatives
If a user lacks the required subscription to access an article behind a paywall, EndNote Click suggests free, alternative legal versions of the content that might be available on open access platforms.

Integration with EndNote
The extension allows users to send the reference of an article directly to EndNote Desktop or EndNote Online. When you click on the pop-up icon displayed by EndNote Click, the article is added to your EndNote Click locker. From there, you can export the reference to EndNote Desktop as a RIS file or push it directly to EndNote Web, which also attaches the PDF to the reference in your EndNote library.
Browser Compatibility
EndNote Click is available on multiple browsers, including Google Chrome, Microsoft Edge, Firefox, and Opera. Users can install the extension from the relevant browser store or through the Tools menu in EndNote Desktop if it does not install automatically.
Personal Account and Institutional Setup
To use EndNote Click, users need to create a personal EndNote Click account, which is separate from their EndNote online account. Users must also select their home institution to connect to the university’s subscriptions, ensuring access to institutional resources when using the extension off-campus.
Storage and Management
The free version of EndNote Click provides 100 MB of storage in the EndNote Click locker. Users can manage their storage by deleting PDFs from the locker after adding them to their EndNote library. This helps in keeping the locker organized and within the storage limit.
AI Integration
The AI technology in EndNote Click enables the automatic detection of user subscriptions and the suggestion of alternative open access versions of articles. This AI-driven approach streamlines the process of accessing research materials, making it more efficient and user-friendly.
Conclusion
In summary, EndNote Click combines AI-driven subscription detection, open access suggestions, and seamless integration with EndNote reference management tools to provide a streamlined and efficient way for researchers to access and manage journal articles.
