I use audiobookshelf to manage my TTRPG pdfs. It can correlate multiple files under one “Title” which makes organizing ttrpg stuff simple and it’s a nice interface. Plus it’s self host able so I can share it with the other people at my table. I just wish the PDF reader was a little more robust but it mostly does the job.

Unless you’re like me and the websites you use for work require it and don’t work in literally any other browser (I have tried everything)
