archive vs Folio

It's arXiv preprint search & PDF viewer app. All features are completely free to use. arXiv.org e-Print archive https://arxiv.org/ URL scheme: preprint:// Note: - This app uses arXiv APIs. - This app is run by an individual and has nothing to do with arXiv. Thank you to arXiv for use of its open access interoperability. --- * arXiv arXiv (pronounced "archive"—the X represents the Greek letter chi [χ]) is an open-access repository of electronic preprints and postprints (known as e-prints) approved for posting after moderation, but not peer review. It consists of scientific papers in the fields of mathematics, physics, astronomy, electrical engineering, computer science, quantitative biology, statistics, mathematical finance and economics, which can be accessed online. In many fields of mathematics and physics, almost all scientific papers are self-archived on the arXiv repository before publication in a peer-reviewed journal. Some publishers also grant permission for authors to archive the peer-reviewed postprint. Begun on August 14, 1991, arXiv.org passed the half-million-article milestone on October 3, 2008, and had hit a million by the end of 2014. As of April 2021, the submission rate is about 16,000 articles per month. Quoted from: https://en.wikipedia.org/wiki/ArXiv

Folio turns staying current with research into something you actually look forward to. Instead of cluttered tables and endless tabs, you get one paper per screen — swipe up for the next, just like your favorite feed. Pulled live from the open-access world: arXiv, bioRxiv, medRxiv, OpenAlex, Europe PMC, and Semantic Scholar. Whether you're a researcher, a grad student, or just science-curious, Folio meets you where your attention already is. WHY FOLIO • One paper at a time - a calm, full-screen feed instead of noisy lists • Real coverage - millions of preprints and papers across physics, biology, medicine, CS, and beyond • Math that renders - equations display properly, not as broken symbols • Save & tag - build your own library and organize it your way • Tune your feed - pick the sources and topics you care about • Fast and private - your library and settings live on your device, no account required OPTIONAL AI (BETA) Want a hand making sense of a paper? Folio's optional AI features can: • Summarize at your level - explain-like-I'm-12, standard, or expert • Ask the paper - get answers grounded in the abstract • Translate - read papers in your language • Synthesize - pull themes across a set of papers AI is completely optional and off by default. The whole app works without it. During the beta, AI runs on your own Anthropic Claude API key, stored only on your device — there's no subscription and nothing to buy inside the app. NO ADS. NO TRACKING. NO ACCOUNT. Folio doesn't sell your data and doesn't show ads. Your saved papers, tags, and settings stay on your device. Science moves fast. Folio helps you keep up - one swipe at a time.
