Products that do what GPT Classifies HN Titles does
With all the "what can GPT do", I went to dabble with it to see if I could do something that plays to its strengths rather than just speculating about "would it be good at that?" https://gist.github.com/shagie/ff2f67b33bb517f6a297e2da66530cf4 The basis for the prompt is: Classify following titles into one or more of {US Politics}, {World Politics}, {Technology}, {Security}, {Current Events}, {Boasting}, {Curiosity}, {Unknown} The results from the front page as I type this: 34152137 Technology: Lite XL: A lightweight text editor written in C and Lua 34151880 Curiosity:…

I’ve been hacking on a project called Bookshelf (https://www.bookshelf.diy/). It lets you take an archive — say, your Substack export, a bunch of PDFs, or even saved HTML files — and turn that into a retrieval-backed GPT that your readers can query. The idea is: instead of scrolling archives, they just ask questions. Answers are pulled only from your original content, with citations. It’s aimed at writers and researchers who want their work to be more discoverable — but without spinning up vector infra or fiddling with RAG pipelines. For context: I’ve always gone back to Paul…

Hi everyone, I read HN every day, but there was always more great content than I had time to read. I know there are already several HN summarizers on GitHub, and I tried some of them. They just didn't fit the workflow I wanted, so I decided to build my own. My project is a self-hosted app that automatically fetches top stories, summarizes them with AI, translates them into your preferred language, and prepares a personalized daily briefing in a nice customizable UI while you sleep. Maybe I'm not the only one who wanted this kind of workflow. I'd love to hear your thoughts, especially on what…

Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

It it always bugged me when I read or share an article, the discussion lives separately from the article. I imagined being able to add Google-Docs or Notion style comments on any website. We save a snapshot of the website and allow adding discussions that live side-by-side and directly reference parts of the article. HN articles are automatically indexed in https://cooo.link/hackernews and you can add any website, PDFs on https://cooo.link/ Built with SvelteKit, SingleFile(for archiving page), Railway. Solo dev. Would love feedback if you found it interesting!…

Hey all, we've seen increasing interest for leveraging GPT's capability but basing it off of your own data so we launched a new feature "Ask Relevance" a little while ago and our users have loved it. There have been some great tutorials on how you can do this and we thought we'd share our approach with the community as we believe it's very accessible. Under the hood, it's using vector search to extract relevant content from the dataset and then using that to feed it into GPT. The post features a video where you can see it in action answering specific questions about the Relevance AI…

We did a quick side project over the weekend and called it HN Trends (while posting we realized there was an older site with the same name so hopefully there is no confusion). We wanted to see what was trending in terms of keywords (buzzwords, tech, etc) and found a nice API. URL: http://www.hntrends.com Let us know what you think - thanks!

I'm building an AI platform, FlowChai and found a neat use case for it today that I thought would be useful to HN readers. I use GPT4 heavily for writing / editing code, but a major downside is that it doesn't know about new projects. I made the connection today that I could upload the zip file of a Github repo to FlowChai and then write prompts just like with ChatGPT with code questions. While the original intent for this platform is more around natural language, it's neat how this works so well. It's powered underneath by pgvector and OpenAI embeddings.

We’re George and Ann, and want to share a Hacker News specific browser extension that we have been working on. We all love the rich discussions in HN, but navigating long posts with multiple threads can sometimes be challenging. You get lost in the depth and breadth of the discussion. There are a few AI-based summarization tools, but they typically focus on summarizing the article rather than the comments, and thus miss the essence of threaded discussions. So, we built Hacker News Companion, a browser extension that makes it easy to navigate discussions and understand diverse viewpoints…

I'm building a Telegram bot to practice Dutch. GPT-4o-mini kept picking vocabulary words I already knew, so I built a classical NLP pipeline to do it instead. It takes a short text + learner level (A0–B1) and returns the best words to study, using Stanza for parsing and corpus frequency ranks (SUBTLEX-NL, srLex, SUBTLEX-US) for scoring. Wins at A1/A2, loses at A0 where the LLM picks more obvious words. I also tried adding multi-word phrases (ADJ+NOUN, VERB+NOUN, phrasal verbs) backed by NPMI-scored collocation whitelists. Couldn't beat GPT there because it just "knows" which phrases…

Been feeling a bit left out in this fast paced world of ML/AI, so built my first ML project since college. The idea is to scrape the most recent HN article titles and use TF-IDF and cosine similarity as metrics to rank articles that you're interested in to filter out only relevant things. Hopefully a fun project for beginners to get inspiration to jump into this world.

Hi HN, I'm Chun Rapeepat. Last week I started playing with GPT-4 and tried different ways to use it to optimize my dev workflow. It was fun, and I was just blown away by what GPT-4 can do. The idea of CodePrompt first came to mind when I read "Show HN: GPT Repo Loader – load entire code repos into GPT prompts" [1]. It was precisely what I wanted to do! So I tried it. The GPT Repo Loader works pretty well on a small codebase; However, due to its limitations in loading all files and content into the prompt, I still ran into token context limit issues and needed to copy/edit the code…

Hi HN, Today we're launching a tool to help you evaluate and test prompts for Generative AI. We have been building different GPT3 apps and noticed a gap in tooling to help developers assess the quality of different prompts. Our tool helps you template and test on different datasets and LLM models like GPT-3, GPT-3.5 and open source models like flan-t5-xxl. We are just getting started and would be delighted to receive your feedback.

I've been lurking on HN for years. You know the drill: interesting headline, 200+ comments, you dive in thinking "I'll just skim for 5 minutes"... and an hour later you're 36 chambers deep in a thread about memory allocation patterns in Postgres and you've completely forgotten what the original article was about. I don't just want a "summary" (which usually just shortens the noise). I want the meta-consensus: "What is the actual trade-off being debated? Who is winning the argument? Why does this matter?" So I built HNSignals. Think of it less like a "summarizer" and more like a Chief of…

I love HN, but lately I have been sick of reading the same dismissive criticisms over and over again. Along with political arguments that have been litigated to death, people's issues with smooth scrolling on blogs, etc. Many of these comments do not get flagged for whatever reason. So I made a service to automatically classify whether comments violate (a modified form of) the HN guidelines automatically. In addition there's a Chrome extension to collapse these comments (if they violate your score thresholds) so you don't have to read them too. You can also just watch guideline violating…

I vibe-coded a small project that turns the “Ask HN: Who is hiring?” thread into searchable job data using OpenAI, PostgreSQL, and Metabase. It pulls the thread using the Hacker News API, uses GPT to extract fields like company, role, location, salary, and contact, stores everything in PostgreSQL, and spins up Metabase so you can explore and search the results. Right now it runs locally, but would anyone be interested if I built this out a bit more and made a public dashboard?
