A warm, distraction-free reading surface with everything a page deep, always a click away.
The tide had turned by the time she reached the quay, and the whole harbour lay silvered under a low and patient moon. She opened the book where she had left it — a ribbon of gold between the pages — and let the evening settle around her like a shawl. There was no hurry here, no glare, only the soft amber of the lamp and the slow, deliberate turning of a page.
The powerful Readium engine plus the small touches you notice every evening.
Font, line spacing, margins, brightness, night and sepia modes — read exactly the way that feels right to you.

No ads, no profiling. Your library, notes and reading progress never leave your device.
A built-in amber filter warms the whole screen to cut blue light — kinder to your eyes on late nights. Four levels, always a click away.
Let the pages turn themselves at your own pace — Slow, Medium or Fast. Sit back, settle in and simply read.
Opens in a warm, easy-on-the-eyes light theme by default — with a one-click switch to a cosy dark mode whenever you like.

A note on Windows SmartScreen. Because Paperluna is a brand-new release, Windows may show a one-time “Windows protected your PC” notice the first time you run the installer. This is normal for new software that hasn't yet built download reputation — choose More info → Run anyway. The installer is digitally signed — the User Account Control prompt should show the publisher as ANTIDEMON SOFTWARE LIMITED, and the checksum above lets you confirm the file is genuine.
Download Paperluna and turn any evening into a quiet, unhurried read.
