   Built a tool solve the nightmare of chunking tables in PDF vs. Markdown▲15

   Hey HN, solo dev here. After years of frustration with how LLMs handle complex documents, especially PDFs with tables, I decided to build a solution myself. My approach uses a Markdown conversion step to preserve the table structure, which seems to work surprisingly well for chunking. This little parser is the first public piece of a much larger, privacy-focused AI platform I'm building. I'm pretty much running on fumes financially, so any feedback, critique, or support is massively appreciated. Happy to answer any questions about the approach!

   Doctly AI – Accurate AI-Powered PDF to Markdown Parser▲7

   I’m one of the co-founders of Doctly AI. I wanted to share our story. We didn’t originally set out to build a PDF-to-Markdown parser. It all started when we were building a RAG solution for a company that deals with regulatory agencies. All of their data was in PDFs, and as it is apparently with lawyers, they like to print and scan documents to make it hard on their counterparts. These documents contained complex tables that barely make sense, are rotated, and handwriting is mixed in between. Many pages are number ruled and potentially rotated. We spent a lot of time trying to get clean data…

   Markdown Converter ▲12

   Hey HN I built MarkdownConverters.com — a tool that converts any file format (PDF, DOCX, PPTX, HTML, or URL) into clean, structured Markdown. I often needed to prep documents, reports, or scraped pages for AI pipelines, documentation, or version control, but existing tools either broke formatting, lost code blocks, or produced unreadable Markdown. So I built something that focuses on: • Accurate structure (headings, lists, tables, code, links) • Consistent Markdown output ready for LLMs or docs • Fast, browser-based conversion with privacy-friendly processing • Support for multi-format and…

    Papermill Press – An AI-friendly markup language for PDF generation▲18

    If you’ve generated PDFs from HTML, you’ll know the pain: headless Chrome in Docker, CSS hacks, content that flows over pages or table boundaries and other quality issues. The fundamental problem is that HTML was designed for screens, not print. We built Press, a markup-based document language where pages, content flows, and assets are first-class concepts. Content can flow across frames, columns, and pages without manual pagination. Pages are created dynamically based on the available content. Press templates separate layout from content. You can send markdown, Press markup, or a mixture of…

    Pdf-to-Markdown CLI▲6

    Hi HN! I'm proud to share that we've launched a free PDF-to-Markdown CLI built on our proprietary (you might know it from PSPDFKit) engine. Most extractors are either fast but lose structure (markitdown, pymupdf4llm) or accurate but slow (docling). Ours ties with docling on accuracy but is orders of magnitude faster. https://github.com/pspdfkit/pdf-to-markdown We'd love feedback on it, and ofc send us files that break it.

    PDFBolt▲16

    Hi HN, I'm Michał. I posted PDFBolt here about a year ago as a basic HTML to PDF API. Since then I've been rebuilding it around the thing that kept bugging me: every time a designer tweaked a layout, it meant a code change, a deploy, and a prayer that nothing broke in production. I wanted templates that live on the server and version themselves, so my API calls stay the same when the layout changes. Try the editor, no sign-up. Open a sample report, change the data, and download a real PDF: https://pdfbolt.com/try Templates use Handlebars. Your API call sends a templateId +…
