@ty.prompts.ai: Adobe wants a subscription so you can sign a PDF. These 5 free repos do the whole paperwork job and none of them send your documents anywhere. Stirling PDF is the big one, 89k stars, and its own README says it: edit, sign, redact, convert and automate PDFs without sending documents to external services. Paperless-ngx turns the pile on your desk into a searchable archive, or as it puts it, so you can keep well, less paper. MinerU handles the messy real world stuff, scans and Office files full of tables, and turns them into clean markdown. Unstract is the clever one: you describe the fields you want in plain English, invoice number, total, due date, and it hands you back JSON you can call as an API. And docling gets a document ready for your AI app in one step. Save this before your next tax season. Repos: 1. Stirling PDF - github.com/Stirling-Tools/Stirling-PDF 2.
