Show HN: Bring-your-own-key browser extension for summarizing HN posts with LLMs

74 pointsby ivanyu5 months ago
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&#x27;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:&#x2F;&#x2F;chromewebstore.google.com&#x2F;detail&#x2F;hacker-news-tldr&#x2F;oobfhfehiidchknmihplkgknbjolanlk" rel="nofollow">https:&#x2F;&#x2F;chromewebstore.google.com&#x2F;detail&#x2F;hacker-news-tldr&#x2F;oo...</a><p>[2] <a href="https:&#x2F;&#x2F;addons.mozilla.org&#x2F;ru&#x2F;firefox&#x2F;addon&#x2F;hacker-news-tl-dr&#x2F;" rel="nofollow">https:&#x2F;&#x2F;addons.mozilla.org&#x2F;ru&#x2F;firefox&#x2F;addon&#x2F;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. <a href="https:&#x2F;&#x2F;hackernews.betacat.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hackernews.betacat.io&#x2F;</a> I also dislike how the titles on hacker news are so short that often they dont give enough information. e.g. headline: &quot;Amazon Penterhorse&quot;. What is that?? that doesn&#x27;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&#x27;s blog post is just way longer than my interest level so it doesn&#x27;t get the point across. These summaries are just the right length.

Would be nice to be able to provide your own endpoint so it could be directed to a local llm.

This is so weird, why does every user has to use their LLM subscriptions&#x2F;keys instead of just storing the summarization of the HN posts as a static website somewhere? (e.g. summarize once for all users)

I&#x27;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&#x27;m able to quickly build an Arc &quot;Boost&quot; 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&#x2F;categorizing comment threads by the patterns of knowledge crystallization etc. It&#x27;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:&#x2F;&#x2F;github.com&#x2F;simonebrunozzi&#x2F;MNMN">https:&#x2F;&#x2F;github.com&#x2F;simonebrunozzi&#x2F;MNMN</a>

I&#x27;d love it if it could summarize the HN comments as well.

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&#x27;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&#x27;s a browser extension.

This sounds possibly useful, but I just don&#x27;t trust extensions unless I can see the code.
