Linkeddit▲618The tool actually hit Product Hunt #1 back in February. Since then I’ve added a bunch more on top of the original version. Now you just describe the intent or goal for the leads you want, and it searches based on keywords and a bunch of other signals to surface the best ones for you. I also added a Reddit-powered content writer. Basically, you pick a topic or category, and it pulls the top posts from Reddit, analyzes what made them go viral, and helps you write content using the same patterns. Reddit is super underrated for content. If something blows up there, it almost always spreads to…

A01▲545Hey everyone, I feel like a lot of us have gotten used to social media as our main way to stay informed. It’s where we get our news, trends, opinions, and everything. But honestly, my attention has been wrecked by it. TikTok, X, Instagram... I go in to check one thing and suddenly I’ve lost 90 minutes. So I started wondering what if we could actually control what we see? Like, fully. What if we could own our feed instead of letting the algorithm choose what we scroll through? To play with that idea, I built a small demo app. You just type in what you want to follow, like “recent crypto big…

Hey HN! We're building an open-source CMS designed to help creators with every part of the content production pipeline. We're showing our tiny first step: A tool designed to take in a Twitter username and produce an "identity card" based on it. We expect to use an approach similar to [Constitutional AI] with an explicit focus on repeatability, testability, and verification of an "identity card." We think this approach could be used to create finetuning examples for training changes, or serve as inference time insight for LLMs, or most likely a combination of the two. The tooling we're…

Hi HN! This is a personal project I finally got round to completing and shipping. It’s a simple feed of articles written by real people with interesting things to say. I wanted to explore some new technologies I haven't had a chance to try before, mostly rust and LLMs. As I browse HN each day I find myself most drawn to the content on personal blogs: people who have interesting things to say, from their own point-of-view, on a whole range of topics. Rather than being interested in particular topics, I’m more interested in reading from interesting people. This isn't a particularly new idea,…

MacroPulse▲20Hi HN, my friend Ivan and I are retail investors and consume financial news regularly. We both think the current finance news is unwatchable, filled with exaggerated titles, writer bias and anecdotal details, so we built MacroPulse to make the financial news app we want. MacroPulse aggregates financial news, and the AI creates a single concise summary with key points for every stock daily. If you want to know the details, you can click the key points, the AI will give you extensive details. With the new format, I hope we can save you time while making you learn more about the details.…

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…

Capitally▲24Hey HN, As someone who geeks out on both investment data and privacy tech, I built Capitally to scratch my own itch. It's encrypted on-device so that once I can afford to hire a second engineer, he cannot peek into my own data! I wanted a way to monitor ALL my investments (stocks, crypto, real estate, angel investments, etc.) in one place and really dig into the data - but without compromising my privacy. Here's how Capitally makes that possible: On the data side: Import data from CSVs, spreadsheets, or any other source via a flexible no-code editor Map any data format into a standardized…

Hi HN, I’ve been working on Masari Cabal, a social platform designed for traders and investors who want focused discussions around markets like stocks, crypto, forex, and commodities. The main features: • Private channels for sharing market insights • A system where contributors can optionally monetize their content via private posts or group memberships • Clean, distraction-free design aimed at serious market participants The motivation came from frustration with how scattered and noisy discussions get on mainstream platforms like Twitter and Discord. My goal is to provide a space where…
