    Hi, I've just finished a rebuild of this function and added a lot of new features: info, page index, minimap, inverted index,... I think it may be useful for inspection, debugging or just as a learning resource showcasing the PDF file format. This is a pet project and I would be happy to receive some feedback! Regards

    I built EmbedPDF: an MIT-licensed, open-source PDF viewer that aims to match all of Adobe Acrobat’s paid features… for free. Already working: - Annotations (highlight, sticky notes, free text, ink) - True redaction (content actually removed) - Search, text selection, zoom, rotation - Runs fully in the browser, no server needed - Drop-in SDK for React, Vue, Preact, vanilla JS Why? Acrobat is heavy, closed, and pricey. I wanted something lightweight, hackable, and embeddable anywhere. Demo: https://app.embedpdf.com/ Website: https://www.embedpdf.com/ GitHub:…

    Hi HN, I'm a film director by trade, and I prefer writing my stories in plain text rather than using clunky screenplay software. Standard markup like Fountain doesn't work for me because I write in mixed languages, so I use Markdown with a custom syntax I invented to resemble standard screenplay structures. This workflow is great until I need to actually generate an industry-standard screenplay PDF. I got tired of manually copying and pasting my text back into the clunky software just to export it, so I decided to write a script to automate the process. That's when I hit a wall. I tried…

    I started writing this book 10 years ago in JavaScript, got through a few chapters (asymptotic notation, basic techniques, start of sorting), and then abandoned it. Recently I picked it back up, converted everything to TypeScript, and used AI (Zenflow [1] + Claude Opus 4.6) to complete the remaining chapters. I provided the structure, direction, and initial chapters; the AI generated the bulk of the remaining content under a spec-driven workflow. The book covers roughly a first 1-2 year CS curriculum: sorting, dynamic programming, graph algorithms, trees, heaps, hash tables, and more. All…

    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!

    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:&#x2F;&#x2F;pdfbolt.com&#x2F;try Templates use Handlebars. Your API call sends a templateId +…

    Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https:&#x2F;&#x2F;typeitjs.com&#x2F;build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…

    If you just want to use it, try here - https:&#x2F;&#x2F;pdf2md.trieve.ai . I think the LLM's are astoundingly good at converting complex powerpoint style infographics. I wouldn't normally think folks on HN would find this interesting as the general concept has been posted about already in the past few months. We were heavily inspired by Zerox[1]. However, the stack we went with was fun and over-engineered which is more likely to create interesting discussion. We use all the same tools at Trieve (our main product), but wanted to see if they would be a good fit for something that needed to…

    Hey HN, Sharing a web app I built for converting PDFs to Markdown. I was tired of broken tables and formulas, so I focused on making sure those elements (along with headings and text) convert cleanly.
