It’s perfect! Do you guys already do this?
I open a letter, I take it’s picture with FairScan. The FairScan-folder on my android device gets syncthinged to the ingest folder for Paperless-ngx on my “server”. Paperless imports it, deletes the file and sets the new documents tag to inbox. I decide if the document goes to the binder for important stuff, or if I just toss it in a binder with all the paper I most likely will never touch again. Next time I look at Paperless, I edit all documents with the inbox tag and remove the tag.
Paperparrot is flawless. The dev is also very responsive and helpful.
They also offer a similarly flawless app called Plappa as frontend for your audiobookserver.
Running both, super happy.
