Every Android reader either mangles study material or wants an account first. GemReader does neither. Textbooks, lecture PDFs and interactive workbooks in one offline library. Workbook answers save themselves. Highlights become a spaced-repetition deck inside the reader — no export step — and existing Anki decks import. Everything is encrypted on the device. No account, no cloud, no telemetry, no ad SDK. Everything in the app today is free and stays free.
On money, so nobody has to guess: everything in the app today is free, with no ads and nothing gated, and it stays that way. We do plan a paid version later, but it would be built out of features that don't exist yet — not a wall put up around what you're installing today. It isn't open source, and I'd rather say that plainly than be vague about it; the manifest and the network behaviour are both fair game to check.
I'd genuinely like feedback on the study loop — highlight, review, repeat — and on what's missing for the way you study. I'm here all day.

I’m thrilled to be a launch partner for GemReader! 💎
Beyond creating a beautiful, joyful reading experience, our top priority was simple: surface your highlights, notes, and hidden gems seamlessly.
But just as importantly—in a hyperconnected world designed to monetize your data—we built GemReader to be completely private. What you read and write is your business, period.
That’s why we’ve gone to great lengths to build this right:
End-to-End Protection: Your data is heavily encrypted both at rest and in storage.
In-Memory Processing: We process your notes and reading data in memory so it doesn't leave unnecessary trails.
It required a ton of extra engineering effort, but keeping your personal library completely shielded from unwanted eyes is a payoff we think is 100% worth it.
