Ask HN: Thoughts on building an AI Twitter search tool?

Here's my dilemma: Twitter (to me) is fairly toxic and I get no joy in using it. However, it's still the best place I've found to find revenant news about topics I care about.

AI has had so many initiatives for creating content and pushing content into our feeds... seems really fun to think of how AI can help platform users for a change.

I'm hoping to build or find something that can search twitter for me and present a list of tweets, filtered on sentiment. Obviously a topic like "CSS" is full of rants and debates and self-promo, but I think current AI could actually do a reasonable job of surfacing the interesting bits.

Just curious if anyone could point me towards the "stack" they'd use for such a project. I'm a seasoned web developer but a bit novice about AI and struggling to sort where to begin. Many thanks for any replies! Plan to open source whatever I build for this.
