Researchpal

ResearchPal is a extension for Chrome and Edge that lets researchers save, scan, and manage research PDFs directly from the browser toolbar into their personal PDF library.
Core Features
Quick Save — If you're on a PDF page, the popup pre-fills the URL automatically. You can enter any PDF URL and a title to save it to your library in one click.
Bulk Scan — Navigate to any page listing multiple papers (e.g. a university archive or journal index), click "Scan Page," and the extension automatically detects all PDF links on that page. You can then selectively check/unchecked files and bulk-download them with a real-time progress bar.
Library Browser — A built-in tab lets you browse all saved PDFs, showing file size and relative save time
