24 alternatives to WhatHappened – HN summaries, heatmaps, and contrarian picks

Hi HN, I built WhatHappened (whathappened.tech) because I have a love/hate relationship with this site. I love the content, but the "wall of text" UI gives me FOMO. I was spending too much time clicking into vague titles ("Project X") or wading through flame wars just to find technical insights. I built this tool to act as a filter. It generates a card for the top daily posts with a few specific features to cut the noise: 1. AI Summaries: It generates a technical TL;DR (3 bullet points) and an ELI5 version for every post. 2. The Heat Meter: I analyze the comment section to visualize the…

WhatHappened processes top Hacker News posts daily and presents them on cards with AI-generated summaries (both technical and simplified versions), a heat meter showing comment section tone distribution, and contrarian… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    I love Hacker News but I rarely have time to read full articles / comments, so I built a simple site to summarize the top posts & comments to make it easier to get a big picture. A few implementation details: - It pulls the top stories from the HN Firebase API (`/v0/topstories`) - Filters stories with >200 points - Uses Claude Sonnet for post + comment summaries - Tries to capture the sentiment of the comments (still working on improving this) - Refreshes both posts + summaries hourly It has already helped me I hope it helps you! Please let me know if you have any feedback --…

    Hey there HN! I wanted to share a pet project of mine. I built HackYourNews [1] to scratch a personal itch: Knowing which stories to focus on while browsing aimlessly (though there is a certain joy in that, as well!) HackYourNews uses OpenAI's gpt-3.5-turbo to summarize the destination article as well as the comments section. Summarization of the article is always cached, while summaries of the comments are regenerated if the comments count is >10% (or >10 comments) different. While I styled the homepage to welcome HNers, my preferred view is the Mobile view, accessed from the navbar. This…

    Hey HN! Just for fun, I built an interactive Hacker News Simulator. You can submit text posts and links, just like the real HN. But on HN Simulator, all of the comments are generated by LLMs + generate instantly. The best way to use it (IMHO) is to submit a text post or a curl-able URL here: https://news.ysimulator.run/submit. You don't need an account to post. When you do that, various prompts will be built from a library of commenter archetypes, moods, and shapes. The AI commenters will actually respond to your text post and/or submitted link. I really wanted it to feel…

    Hi HN! I’ve been lurking for a while, but out of fear of being steamrolled by HN readers or maybe just natural introversion, I’ve always been too scared to post or comment. Which is why 1. this is my first real Hacker News submission 2. my friend Michael and I built "Fake" Hacker News, a place to post and see what AI-generated HN comments might say. Here’s a video of me using fakeHN to test this very submission: https://www.loom.com/share/4b9f4f9d7c77489a86baeb92ec55a1ed?... And an example of one of our generated posts:…

    I made a little website with a server that collects only HN submissions with > 500 upvotes chronologically. https://hn.moritz.pm/ It's quite simple because I wanted to learn from the project. But I think it's useful, to get a summary of what was important over the last days. The UI is almost identical to the HN frontpage, you can click on the comments to view the thread and on the username to see the profile. The rest of the cards takes you to the submitted URL.

    Hi! I’m Julien and I built a recommendation engine for Hacker News. I feel like this website is a gold mine. Every day, I find some very interesting stories about a topic. And sometimes, I want to find other stories covering that same topic but I can’t. Hacker News has years of history of awesome discussion and ressources. Unfortunately, I think HN Algolia isn’t helpful in searching these old threads. As a student, I want to learn a lot from this website. This is why I created HN Recommend. Input a sentence or the URL of an article, and get the most popular and similar posts from Hacker…

    I built this tool to help me find interesting discussions on Hacker News. I love reading HN discussions almost more than the articles themselves. However, I found that full text search, although highly performant, is not always good at surfacing interesting discussions on a certain topic -- especially if you don't know what to search for exactly. I built this by scraping the most recent ~6 million posts (that's about 2 years of history) and putting the resulting posts and their vector embeddings into Postgres. Let me know what could be improved, and if you'd like a more detailed writeup of…

    Hi HN, I spent a few weeks looking at the top HN posts of all time. This included exploration, clustering, creating visualizations, and zooming in on what (to me personally) seems like some of the best discussions on here. Three things in this post: 1- The interesting groups of HN posts 2- The interactive visualizations that you can explore in your browser 3- The data from this exploration -- this includes CSV of the titles as well as the text embeddings of 3,000 Ask HN articles. Blog post about this whole process here: [1] ============ 1- The interesting groups of HN posts From the…

    Hey HN. I created this website. https://pj4533.com/hn-overlooked/ It's just a simple web app that discovers overlooked posts on Hacker News. I created it because I was often coming to Hacker News and realizing that I was missing a lot of stuff, and there just didn't seem to be an easy way to surface content that was interesting to me but just didn't bubble up to the top of the page. So I built this. I got the idea a while back, one night when I was recording (you can watch it here, it's pretty funny: https://youtu.be/FDyDb4sX30w?si=E3rby-DaGWA6gy0R ). But I…

    I love HN but always felt the search with algolia is okay but does have some limitations. Since I work at Vectara I decided to try and create a better search for HN. It's based on data from roughly the last 6 months of HN stories and comments. Would love to hear feedback and how useful this is relative to the existing search.

    Hi folks, I've built an alternative Hacker News front page. It is inspired by and meant to be a replacement for hckrnews.com. I built this because HN is woefully underfeatured, but most sites that try to improve it seem to assume that the visual design is the problem. hcker.news tries to maintain HN's familiarity while adding useful enhancements. There are three primary views: - Timeline View: Browse top stories by votes or comments grouped by day, week, or month (e.g., top 20 per day, top 100 per week). - Aggregate View: See top stories by votes or comments over custom time ranges. - Front…

    http://www.hnshowcase.com Moses (nnythm) and I browse Hacker News daily. Show HN posts are some of our favorite parts of HN. We wanted to create a way to browse Show HN articles, even those that might not quite make it to the front page. We created http://www.hnshowcase.com last weekend to make discovering projects posted on HN easier. It searches all "Show HN" posts and generates a thumbnail view for each of them. You can sort by submission date, points, and number of comments, and navigate with left/right or j/k keys. We used the following technologies: HN Search API, Pyramid web…

    HN Summary is an open source bot which sumarizes top stories on Hacker News and publishes the summaries to a Telegram channel. Whenever a new story appears on the Hacker News API /topstories.json endpoint, this bot summarizes it (currently using OpenAI GPT-3 text-davinci-002) and sends the story title, summary, and url to the hn_summary channel on Telegram. The purpose of this project is to help build intuition on the capabilities of the current generation of large language models while making a broader swath of top Hacker News content more easily accessible. It could also serve as a…

Here's a screenshot: https://github.com/haojiang99/hacker_news_reader/blob/main/s.... As a daily HN reader, I've always struggled with keeping track of interesting posts I want to read later. Browser tabs pile up, bookmarks get forgotten, and I lose track of what I've already read. I needed a way to: 1. Browse HN efficiently (across all sections - hot, new, show, ask, jobs, best) 2. Quickly mark posts as "todo" for later reading 3. Mark posts as…

    HN has some of the best discussions on the internet, but I don’t love reading 100 comments to find 10 great insights. This site analyzes top HN threads with LLMs and summarizes the key ideas, disagreements, and resources — while preserving links to the original discussion. Useful for revisiting old threads as well. Updated daily, manual-assisted for quality, no spam, fan project only. Would love thoughts from the community. https://hn-discussions.top

    Hey folks, http://dstill.ai/hackernews is alternative frontend for Hacker News, with some features on top: (1) AI powered summarizations. Summaries are generated for the link, for the post and for the discussion. Summaries are automatically generated for selected top stories, but you can also generate them on demand — currently this requires supplying your own OpenAI api key (which gets stored in your browser in localStorage). When you generate a summary, everyone else can see it and benefits from it as well. Here are some examples: Summary of a long discussion:…

    A year and a half after I published https://HackYourNews.com, I've rewritten it to be neater and added support for more news sources. HackYourNews.com v1 had a great response on HN [1] and consistently sees ~2k weekly unique visitors. There were many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper dark mode, correct rendering on mobile devices, and more cogent summaries. This rewrite is the result. gpt-4o-mini reduces the cost of summarization to an absurd degree, so it's now sustainable to keep this free service going! Someday, I hope to use…

    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…
