PaperPanda 2 is a Chrome extension designed to simplify the process of downloading scientific papers for research purposes. It addresses the common issue of accessing papers behind paywalls by providing users with a one-click solution to find and download PDFs from various academic sources. The extension is ideal for students, researchers, and academics looking to save time and effort while navigating the complexities of academic publishing.

The tool operates by utilizing its intelligent search capabilities to locate the DOI of the paper from the current webpage. It then queries multiple open access repositories, including OpenAccessButton and SemanticScholar, while also allowing users to configure their university library's domain for tailored search results. With PaperPanda, users can easily download the desired research papers directly to their desktop, bypassing the need for alternative platforms like Sci-Hub or Unpaywall.
