Display a bell emoji on HN comments you haven't read yet

Visit gist.github.com ↗Alternatives

In plain words

This browser extension adds a bell emoji to unread comments on Hacker News, helping users quickly identify which responses they haven't yet viewed. Designed for frequent Hacker News readers, it simplifies comment tracking by providing a visual indicator without requiring additional clicks or navigation. The tool integrates directly into the standard HN interface and is distributed as a GitHub gist.

    I built an interactive HN SimulatorNov 2025 · news.ysimulator.run · ▲538

    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…

    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…

  • Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

    Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
