  • Ask HN: What Are You Working On? (February 2025)
    I'm still working on DocSpring [1], originally launched on Hacker News in October 2017 under the name "FormAPI." 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

Qpdf is a great tool. One of my other favorites is RUPS [2], which really lets you dig into the structure of a PDF.
