Bring-your-own-key browser extension for summarizing HN posts with LLMs
Hi Hacker News, I developed an open source browser extension for summarizing Hacker News articles with OpenAI and Anthropic LLMs. It currently supports Chrome [1] and Firefox [2] (desktop). The extension adds the summarize buttons to the HN front page and article pages. It is bring-your-own-key, i.e. there's no back end behind it and the usage is free, you insert your API key and pay only for tokens to your LLM provider.

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

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…
