I'm working on https://briefin.com/, which turns any topic into a newsletter.

I wanted to replace those passive social media feeds, where I'm just being served what gets clicks. I completely avoided any embeddings or typical rankings, using ai agents instead, to get precise results and things that are actually interesting to me.

Still working on the platform, but I made a tool that already turns Hacker News into a personalized daily digest here https://briefin.com/hackernews/ (with summaries of the discussions)

Let me know what you think :)
