Access millions of research papers for free

Open Access Button is a Chrome extension designed to break down barriers in academic research. We believe that knowledge should be accessible to everyone, regardless of institutional affiliations or subscription access.

Our extension automatically searches for open access versions of research papers and academic articles across thousands of repositories, preprint servers, and institutional databases. When you encounter a paywalled article, simply click the Open Access Button to find freely available versions.

We support the open access movement by connecting researchers, students, and academics with the scholarly content they need. Our mission is to make research accessible to everyone, promoting the free exchange of knowledge and advancing scientific discovery.

The extension integrates with major open access repositories including arXiv, PubMed Central, institutional repositories, and countless other scholarly databases. Our technology uses advanced algorithms to match articles with their open access counterparts, ensuring you find the exact paper you need, even when it's behind a paywall on the publisher's website.

Whether you're a student working on a thesis, a researcher conducting a literature review, or an academic preparing for publication, Open Access Button helps you access the information you need without financial barriers. Join thousands of researchers worldwide who rely on our extension to access scholarly content and contribute to the global movement toward open science.
