  • Ask HN: What Are You Working On? (February 2025)

It's a PDF generation API with a template editor UI for setting up fields on PDF forms. It makes it easy to turn complex tax and immigration forms into simple type-safe APIs with strong validations. I've been having a lot of fun with AI agents lately. Have tried a lot of them - Cline, Roo Code,... - Source: Hacker News / 3 months ago

  • So you want to modify the text of a PDF by hand
    Great post. I've spend a lot of time reading through the PDF specification over the last ~5 years while building DocSpring [1], and I still feel like I've barely scratched the surface. Qpdf is a great tool. One of my other favorites is RUPS [2], which really lets you dig into the structure of a PDF.
