I built a system that monitors ~200,000 news RSS feeds in near real-time and clusters related articles to show how stories spread across the web. It uses Snowflake’s Arctic model for embeddings and HNSW for fast similarity search. Each “story cluster” shows who published first, how fast it propagated, and how the narrative evolved as more outlets picked it up. Would love feedback on the architecture, scaling approach, and any ways to make the clusters more accurate or useful. Live demo: https://yandori.io/news-flow/

An honest to god, non-algorithmic reverse chrono list of tech news that passes my signal-to-noise tests, updated hourly. A lightweight a page design as I've been able to keep; simple, clean, fast. No commercial features or aspirations - this is a passion project, something I've been fooling around with on and off for decades. There's a "Top" view too with an LLM edited front page & summary, and categorized views for a large number of topics - see the Directory. A few more buried features to explore, but the fundamental use case is pop in, scan, exit - fast and concise. Your feedback would be…

Hi HN! Excited to show off the project we've been working on for the last couple months. We started with an idea for a crazy twist on prediction markets: You come up with a question for traders to predict, and then decide the outcome yourself. For example, you could create a market on “Will my date with [X] go well?” Anyone can bet on it, and the bets create a forecast on the chance your date goes well. After the date is over, you get to judge the result and reward the traders who picked the correct side. There are so many ways for this mechanism to go wrong: the creator of the market can be…

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…

Hey HN - my friend and I built Prediction Hunt, a site that aggregates data from prediction markets like Kalshi, Polymarket, and PredictIt into one simple dashboard. It updates every few minutes, shows probabilities for each event, and even highlights arbitrage opportunities when markets disagree. I made it after getting tired of flipping between tabs just to see how each market was pricing the same question. Would love feedback on the product, data accuracy, and any ideas for what you'd want to see next.

One year ago, I downloaded the news.arc code and decided that I would teach myself programming by building a better aggregator. At that time, I had some rudimentary HTML knowledge, and little FORTRAN under my belt. I knew that I wanted an aggregator that could support a wide range of submissions, and one that could scale without losing quality for the user. Hubski is what I have to show for my time and effort. The easiest way to describe Hubski is to say that it uses a commenting system akin to HN or Reddit, but uses a sharing scheme like Twitter. You have a personal feed comprised of the…

Hello HN I visit a few sites news sites daily and wanted to see the headlines all on one page and also have it update itself throughout the day. It is not finished yet, but is usable enough to share. If you want to make a custom page, you can click the 'build your custom page' at the top, and select the feeds that are of interest to you. I haven't implemented it yet, but the feeds can be re-ordered as well, you just need to enter their names in the address bar, for example to show Tech Meme, BBC News and Tech Crunch you would write: nuntium.co.uk/f/?tm,bbc,tc Then bookmark that…

Hi everyone, Not happy with the current news aggregators and thrilled about ML models for text processing, a colleague and I built an aggregator fully based on Doc2Vec: https://www.quicknews.ai/. We currently poll ~120 news sources every 15 minutes, and construct a personalized news feed for every user. There are plenty of ways in which Doc2Vec is used here: 1) Clustering the articles into topics 2) Deduping overly similar articles when generating the feed 3) Routing notifications about breaking news to interested users 4) Calculating similarity between…

I kept losing track of what was happening in AI. It's scattered across Reddit, Discord, Twitter, arXiv, GitHub, Hugging Face. Things slip through constantly. So I built Latent Signal to consolidate it for myself. It's a curated feed for AI news. Right now it's just me, but the goal is for the community to help surface what matters. Covers LLMs, image gen, video, audio, 3D, world models, tooling, and more. The design is entirely inspired by Hacker News. Currently pulling from these sources: - Reddit - arXiv - Hugging Face - GitHub - Hacker News - Lobste.rs You can browse immediately without…

Some people have called StreetEYE 'HN for investors', but it's a little different. You can go to Bloomberg, Reuters, WSJ, FT and hit a page with the most-read stories, but now everyone shares everything on social networks and blogs, so we can try to make one page with the most popular news across all sites and blogs - find the top people who share news, and combine algorithmic, professional, and crowdsourced curation to make the best front page across financial media. StreetEYE is more like a mashup of HN, Techmeme, Google News, Flipboard, Buzzfeed. For now, no comments or submissions to…

Hi HN, I've been a daily user here for almost 15 years. Over that time, my interests have shifted. I find I'm now more interested in deep-dive technical posts and personal blogs than the big tech announcements that often dominate the front page. The "top" feed was starting to feel stale, and I was spending more time digging through "new". So, I decided to build what I wanted: a personalized "For You" feed. Link: https://hn.shaped.ai It's a simple concept: you log in with your normal HN credentials, and as you favorite stories, it learns what you're interested in and re-ranks the…
