All great recommendations here. But I’ve heard good things about PdfDing. I haven’t used it myself but have followed development since the developer is quite active.

Not what you’re asking about, but this guy was very inspirational for me wrt making latex diagrams easily.

Yeah I was just about to point that out for ya.

Paperless ngx has been a game changer for me. I only wish I had a better scanner, or more specifically, a sheet feed scanner which would make scanning stacks of papers way easier.

I’d say give it a shot. All your PDFs are stored nicely in one directory (PDFs are sorted in app by tags) so it’s easy to migrate if you need.
