What it does

Every detail of reading,
considered.

01

Full EPUB 3.3 support

Rich layouts, custom fonts, CSS styling, and JavaScript-powered workbooks that actually save your answers. Everything the spec allows.

02

Beautiful library

Your collection, beautifully organised. Cover art, reading progress, last-opened books. A personal archive that feels considered.

03

Highlights & notes

Mark passages, write notes, revisit them later. Your annotations live with the book, exactly where you left them.

04

Offline. Always.

No internet required to read, annotate, or search your library. Everything works the moment you open the app.

Private by design.

No account required. No cloud sync. No analytics. No tracking. Your library and your reading habits belong to you alone. GemReader works entirely on your device — always offline-capable, always private.
