This is more designed for a self hosted server, so if you want multi-device web access then it's a great solution. I can download a PDF on my android phone and upload it to my paperless-ngx instance in a couple of clicks and easily edit the tags as necessary. It's great for travelling as you're not reliant on having a locally installed application on your chosen device with you, and of course it would still be available if you lost your main device and only had your phone on you.
