arxiver is a Chrome add-on developed by olleh401. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This free program aims to simplify the process of downloading PDFs from arxiv.org by automatically setting the file name for you.

When you click on a PDF on the arxiv.org/abs website, arxiver will automatically enter the title of the paper as the file name. Additionally, there is a toggle feature that allows you to specify the download path for the file. By turning the toggle on, you can choose a specific location for the downloaded file, while turning it off will save the file to the default download folder.

While arxiver may have a simple functionality, it proves to be incredibly useful for those who find it tedious to manually set the title when downloading PDFs from arxiv.org. For more advanced features, searching for Arxive will provide you with additional options such as dividing the file name into title, author, and year, as well as the ability to rename tabs.
