Preprint Reader

Preprint is a fast, focused reader for the latest research from arXiv, bioRxiv, and medRxiv.

Browse a feed built from the subjects you follow, search across three sources, and read papers in a clean native PDF reader. Save what matters, download for offline reading, and keep track of what you have read.

SEARCH THREE SOURCES
Search arXiv, bioRxiv, and medRxiv from one place, and switch source with a tap. arXiv papers open in the native reader. bioRxiv and medRxiv papers open in a built-in web view.

A FEED THAT IS YOURS
Follow categories from any source and your feed fills with their newest papers, newest first. No algorithm and no noise, just the fields you care about.

READ AND ANNOTATE
A distraction-free PDF reader with highlights, bookmarks, a table of contents, and light or dark reading modes. Download papers to read offline.

YOUR READING, TRACKED
The You tab shows a reading activity map, your current streak, and how much you have read across sources.

STAY ORGANIZED
Group papers into collections, tag them, and mark them read or unread. Follow authors to get a notification when they post something new.

PRIVATE BY DESIGN
No account and no tracking. Your library syncs privately through your own iCloud. Clear your history or reset everything whenever you want.
