Yes, Emergent Mind is 100% focused on AI/ML papers from arXiv. I think it makes more sense to focus on a niche because you can tailor everything to that niche, vs creating a general research paper site which won't wind up speaking to any audience well.
For anyone curious about Emergent Mind: it surfaces trending AI/ML papers by monitoring social media (HackerNews, Reddit, X, YouTube, and GitHub) for discussions about papers, then ranks them based on the amount of engagement they're getting (similar to how HackerNews uses upvotes). Then, for all trending papers, it automatically summarizes them using GPT-4o and links to relevant discussions so you can learn more.
We're working on a bunch of new capabilities that we'll announce soon too.
