Read research,
feed-first.
Your reading list is a pile of PDFs. PapyrAI turns it into a feed you can skim, then guides you through a classic three-pass method for reading papers. Spend seconds on the ones that don’t matter and real time on the ones that do.
First 2 papers free.
One-time unlock, no subscription.
§1 Method
Read in three passes.
Researchers don’t read papers front to back. They skim, then go deeper only when a paper earns it. PapyrAI builds that habit into every paper in your library.
- 1 Skim
Every card opens with the paper’s 5 Cs: Category, Contributions, Context, Correctness and Clarity. Decide in seconds whether it earns more of your time.
- 2 Understand
Walk through the figures, collect the references worth chasing, and write the summary in your own words.
- 3 Master
Challenge the assumptions, note the strong and weak points, and sketch the future work the paper leaves open.
§2 Toolkit
Everything a paper deserves.
Once a paper makes the cut, the tools to understand it are one tap away.
- One-page deep dive Abstract, methods, results, limitations, takeaway
- Ask the paper Chat about any paper in your library
- Compare Two papers, side by side
- Timeline Your library by publication year
- Topics Clusters of related papers
- Hero art A cover for every paper, made on-device
- arXiv import Paste a link, get the paper
- iCloud Drive folders Same library on iPhone and iPad
- Library by pass Parked, Done and Skipped shelves
§3 Privacy
Your papers stay
on your device.
Every summary, every answer and every cover is generated by an on-device model. Your PDFs are never uploaded, and there’s nothing to sign up for.

Questions, answered.
Are my PDFs uploaded anywhere?
No. PapyrAI reads PDFs from a folder you choose and runs every AI feature with an on-device model. There is no account and no analytics. The only network requests are arXiv downloads you start, App Store purchases, and optional iCloud sync of which papers used the free tier.
Is it a subscription?
No. Your first 2 papers get the full experience for free. After that, a single one-time in-app purchase unlocks an unlimited library, and you can restore it on all your devices.
Which devices does it run on?
iPhone 16 or newer, or an iPad with an M1 chip or newer (or iPad mini with A17 Pro), on iOS or iPadOS 26 or later.
Where do my papers come from?
Point PapyrAI at any folder of PDFs in Files or iCloud Drive, or paste an arXiv link to import a paper directly.
