Hi HN,

TL;DR: I made a website that takes all the top stories on HN and categorizes them into one of ten topics of interest using LangChain and GPT-4.

I've always liked the idea of getting a personal mix of news tailored to my interests. Hacker News is pretty close to that ideal, which is reflected in the time I spend on here every day.

It's a great mix, but playing with LangChain, I got the idea for a weekend project. Roughly speaking most posts on HN fall into one of these categories:

   * Programming, Software & Computer Science
   * AI, Data Science & Analytics
   * Business & Entrepreneurship
   * Science & Research
   * Cybersecurity & Digital Safety
   * Design, User Experience & Creativity
   * Finance & Economics in Tech
   * Work Culture & Career Development
   * Media, Content & Communication
   * General & Diverse Interests

Using langchain with GPT-4 Turbo (JSON mode), I sort every top submission into one of the above. Costs for using the API are currently at 15$ a month, with few optimizations.

For ease of use I also added the possibility to consume the news topics via a responsive webpage, RSS and email digest (daily,weekly,monthly).

Like this idea. Now you earn one more user :)

A few minor comments.

1/ Current homepage is a bit overwhelmed to read.

2/ The API cost can be greatly reduced (eventually to zero) by caching results, and some text similarity tricks.

3/ Is this going to be a commercial product ?

Thanks a lot!

1) I guess you mean the wordclouds? If so I get your point :)

2) Yes, I though about training my own model eventually once I got enough data

3) No, it's going to be free (and ad-free) for the foreseeable future. I built this for myself and if someone else likes it even better.
