Paperless-ngx is a life-saving tool if you want to digitize and self-host all the documents, invoices, and receipts in a centralized store. I use it because I accumulate hundreds of purchases, documents, paperwork, contacts, quotations, and more in a year. While keeping a physical copy is a good practice, most of these resources exist in either image or PDF format. Paperless-ngx auto-tags documents, which makes it very easy to narrow down your search. I integrated it with Paperless AI a while ago, which utilizes a local LLM to a***yze my entire collection.
