This userscript enhances webpages by detecting DOI links and showing a popup with free PDF sources when you hover over them. It checks availability across Sci-Hub, LibGen, Anna's Archive, Sci-net, and Google Scholar. The popup is dynamically positioned near the mouse and neatly organized into four rows for clarity. It works on all websites and only activates on mouseover to reduce network load. The script is ideal for researchers seeking quick access to academic papers.
