# Nerdi

> Nerdi is an iPhone app (iOS 17 or later) that shows three real research papers a day from 20 fields, from medicine to the humanities. Each paper comes with its original abstract, unchanged, and a free PDF when one exists. Nerdi uses no AI summaries. Papers come from OpenAlex, an open catalog of scholarly research. Reading is free; Nerdi Plus ($29.99 a year in the US) adds an unlimited library, notes, offline PDFs, BibTeX/RIS export and sync. Made by Koray Özcan, a solo developer in Turkey.

Every page on this site has a Markdown version: add `.md` to its address, or send `Accept: text/markdown`.
