    Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

    Recently, I found myself having to read the book "C++ primer" and I just couldn't do it. Maybe my attention span is too little now with Claude and Codex, maybe I'm lazy... but I just couldn't get myself to focus. While reading, I needed something to do. I wanted to talk to the text, I wanted to leave notes, I wanted to use to use my keyboard to quickly flip through pages. The only good available option on a Mac was "Preview" and it was ok, but definitely not there. So I built Quincy primarily for myself. With it you can - "Talk" to the page you're reading, create a quiz about the page, and…

    Hi HackerNews, Lately, I have seen an explosion in posts offering paid APIs/services to get unstructured data into LLMs (i.e. langchain extract, ragflow, unstructured, unstract, just to name a few) and I have been largely disappointed by them, either because they fail to implement multimodal support, fail to give good context for "really tricky" PDFs / Word docs / Powerpoints, or are just plain difficult to use. In light of all these posts I figured I'd share my solution that has been working smoothly for me and my clients. I put it up on GitHub for free so you can check it…

    Hey so I am making my own book reader and wanted to share it with y'all on hackernews and I saw a submission talking about DRM free books[0] so I decided to submit this submission on Hackernews to show what I am upto :-D I prefer minimalism so I have created three different flavors of it depending upon the particular use-cases and I have linked the most minimalist one as the submission. If someone is interested in a Epub/pdf reader, I have recently made one: https://epub.mirror.forum/ After making that, I was also feeling the need of having standard book downloads and…

    Hey HN, I’m Carlos, dev & designer behind Hundred Docs. Here’s the deal: I’ve spent way too many days fighting PDFs in production. Two things drove me crazy: 1. Most doc tools give total freedom → anyone can make a layout disaster + UX is terrible. 2. PDF libraries are a nightmare to integrate So I hacked something that actually works: - You describe the doc in plain English - AI turns it into an editable template - Non-tech folks can tweak it visually - Devs just POST JSON to an API → get a professional PDF back Would love to hear what you think about the product idea and your experience…

    I’ve been frustrated with PDFs and found arXiv HTML lacking, so I built a fully interactive paper reader. Features: • Hover references, citations, equations • Light/dark mode • Auto-generated dependency graphs for definitions/lemmas/theorems • Table of contents that syncs with scroll • Highlighting + annotations • “Copy raw LaTeX” anywhere Featured paper: Video models are zero-shot learners and reasoners (Veo 3) https://www.sciencestack.ai/arxiv/2509.20328v2

    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!

    Hey HN, I built a PDF reader that can generate interactive visualizations right inside the document. The goal is to reduce the “intuition gap” when reading dense papers: select a concept, click Visualize, and it tries to produce a solid visual interactive app where you can rotate/zoom/step through (not just a text explanation). Upload any PDF, select text, click Visualize. Demo (no signup): https://zerodistract.com/try/pdf/67cdee74-810b-4f1b-af7d-010... Product link: https://zerodistract.com I’d love feedback, especially on what feels useful vs.…

    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…

    hey there hn! thought you would appreciate my brand new file format - i've spent over 40 minutes creating this standard. it's really hard trying to get your ideas shown to standards boards etc but i think with the great community here we can help get bioif support into all major browsers :) the spec is available over at the website, as is a reference implementation. it already has higher usage than jpeg-xl. - best
