We launched a closed alpha last week, and our first users are quite pleased with it. One user asked for author-based search for paper recommendations yesterday, and we shipped it within an hour.
Our goal is to make it easy to stay up to date with relevant research and enjoy engaging with it.
We have lots of cool features planned, we’re still very early, and we’d love to iterate with feedback from the HN community.
