Hey HN, maker of papertok here - thanks jslakro for posting this!

Quick intro: I'm a 19-year-old physics student from Spain. papertok is a feed-style app (think TikTok) for browsing scientific papers, pulling from arXiv, OpenAlex and PubMed. It's fully open source (MIT): github.com/mugar123/papertok

Built it because reading papers felt like work and browsing them should feel like scrolling. Happy to answer anything - and brutal feedback very welcome, that's what I'm here for.
