Here's a comparison of Scribd and VPDFS.com:
Founded in 2007, Scribd is often called "the Netflix for documents." For a monthly fee (around $11.99), users get unlimited access to a curated library of over 200 million documents, including academic papers, audiobooks, sheet music, and magazine articles. In 2023, Scribd split its service into three distinct apps: (for ebooks/audiobooks) and SlideShare (for presentations), though the core document repository still operates under the Scribd name. scribd vpdfs.com
