I’m looking to organise my paper mail with the help of a scanner and some document management system for Linux.

Does anybody have any suggestions?

The paperless-ngx project is sort of what I’m looking for, but I don’t really want or need to run it in a selfhosted manner. I have a selfhosted server on which I could easily add it, but since I don’t really need or want this to be available online in any way (even on my local home network) I don’t really want that overhead.

I would prefer an application in the manner of what Calibre is for ebooks. That is, it operates on a locally stored library and that’s it. No web server.
