# PaperDance（纸上跳舞）

> PaperDance is a free web app for browsing arXiv papers like a short-video feed: describe a research topic in plain language and swipe through full-screen cards (key figure, TL;DR, abstract, affiliations, authors, venue, citations; Chinese cards add a one-line takeaway and three bullets). It covers 249,000+ arXiv papers in cs.AI, cs.LG, cs.CV, cs.CL, cs.RO, cs.IR, cs.SD, eess.AS and eess.IV from September 2024 onward, updated twice daily. Likes, saves and comments personalise the feed; the library exports to BibTeX, Markdown, CSV and JSON.
