This tool allows users to quickly find and download academic papers through platforms like Sci-hub, and it includes options to search for books on sites such as Libgen and Anna's Archive. The intuitive toolbar button provides a straightforward way to access these resources, making it easier to obtain scholarly materials without extensive searching.

The extension also features a customizable mirror option, enabling users to select their preferred source between Sci-hub, Library Genesis, or Anna's Archive.
