Hi Hacker News,<p>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).<p>The extension adds the summarize buttons to the HN front page and article pages.<p>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.<p>[1] <a href="https://chromewebstore.google.com/detail/hacker-news-tldr/oobfhfehiidchknmihplkgknbjolanlk" rel="nofollow">https://chromewebstore.google.com/detail/hacker-news-tldr/oo...</a><p>[2] <a href="https://addons.mozilla.org/ru/firefox/addon/hacker-news-tl-dr/" rel="nofollow">https://addons.mozilla.org/ru/firefox/addon/hacker-news-tl-d...</a>
Related: to save on cost, Hacker News is already summarized and available in feed form which I find better than the default front page where you have to read the same headlines repeatedly because the order of the headlines changes on the front page.

I also dislike how the titles on hacker news are so short that often they dont give enough information. e.g. headline: "Amazon Penterhorse". What is that?? that doesn't exist but the point is I have to click through to see it and its annoying. And on some posts when I click on some links the person's blog post is just way longer than my interest level so it doesn't get the point across. These summaries are just the right length.
This is so weird, why does every user has to use their LLM subscriptions/keys instead of just storing the summarization of the HN posts as a static website somewhere? (e.g. summarize once for all users)
I've been pretty happy lately with my setup.<p>Arc browser lets you hover over a link to show a card that summarizes the article.<p>With Claude Projects, I'm able to quickly build an Arc "Boost" User Script for any site, so I have one to export the HN homepage to JSON to import into an LLM. And I have one on comment pages to do the same. I have a userscript to remove pagination so I can infinitely scroll and then export.<p>Ad I have a Claude Project specifically for identifying/categorizing comment threads by the patterns of knowledge crystallization etc. It's been fascinating so far.
Finally!<p>I tried to build something like this a few years back [0], I thought it was a great idea, but LLMs were not available yet, and I was busy with a hundred other things.<p>You can see an example of the summary there.<p>[0]: <a href="https://github.com/simonebrunozzi/MNMN">https://github.com/simonebrunozzi/MNMN</a>
I added something similar into my feed reader. Even summarizes comments. The problem is paywalls, sites that heavily use Javascript, and other bot protection measures (such as OpenAI's blog which I found a little bit ironic). But I guess you might be able to get around bot protections and JS if it's a browser extension.
