Folio: Research Feed

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.
