Paperless-ngx

Paperless-ngx is the project that finally makes going paperless feel achievable rather than aspirational. The workflow is simple: scan a document, and Paperless automatically OCRs it, extracts text, suggests tags and categories using machine learning, and files it in a searchable archive. The email consumption feature is particularly clever — pipe your invoices and receipts through a dedicated email address and they're processed automatically. The search is fast and accurate, making it genuinely useful as a document management system rather than just a digital filing cabinet. What impressed us is how well the ML categorization works after just a few weeks of training. The Docker setup is straightforward, and the web interface is clean and functional. The only real barrier is the initial setup: you need a scanner and some patience to get your existing paper organized. But once it's running, it runs forever.

Best for users who are comfortable following setup instructions or running a self-hosted tool.
