HNRelevant – Add a "related" section to Hacker News

In plain words

It is designed for Hacker News readers who want to discover related discussions more easily.

A browser extension that adds a "Related Submissions" section to Hacker News - imdj/HNRelevant

In the maker’s words, at launch

It's been 2 years since the initial release [here](https://news.ycombinator.com/item?id=36102610). The initial version was a very basic prototype which was not available anywhere beyond the GitHub repo. You had to install it as a userscript or load the extension manually. Since then, it remained simple…

  I was tired of opening 2 tabs for every HN link, so I made a userscriptJul 2026 · github.com · ▲433

  HN is great for the links people share, but a big part of the value I get comes from reading the discussion around them. I realized I was always opening the article in one tab and the comments in another, constantly switching back and forth. I figured there was probably a simpler way, so I threw together this userscript to merge the two. 1. Clicking a link from Hacker News opens the article with a side panel containing the discussion. It doesn't require your credentials, is resizable, and is easy to tweak if you want to customize it. 2. If you land on an article that has previously been…

  Hacker News user experience enhancement browser extension2023 · carina.app · ▲153

  Hello everyone! This is a browser extension that attempts to enhance Hacker News user experience, while your data is kept secure, and private (never leaves the browser). Browsers have evolved significantly since doing a v1 back in 2010, which was one of the contributing factors, for attempting a complete re-take few months ago. Personally, I was surprised how useful it turned out to be when browsing around HN. On the linked page you can find install link(s) from web-browser stores, and demo video/screenshots of the features[1] What do you think ? [1] including, browsing content with…

  I made a search engine for Hacker News2024 · hackernews.demo.vectara.com · ▲211

  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.

  I made a modern web UI for Hacker News2022 · modernhn.com · ▲308

  Hey HN, I made this free browser extension that modernizes the Hacker News design. I previously launched Modern for Wikipedia [1] here back in December, and it seemed like the obvious next choice to build one for HN too! So I've taken what I learned from building that, and have spent all my spare time this year building Modern for HN. I realize this won't be for everyone, but it was a fun project to work on, and I'm really happy with the result so far. Hope you like it too! Lots more planned for future updates, and suggestions welcome :) [1]…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
