Penguin Viewer: Manga Reader

Penguin Viewer is a fast, private reader for the manga, comics and webtoons you already own, with a translator built in that runs entirely on your device. Bring your own files, connect your NAS, and read on iPhone, iPad and Mac. No subscription, no ads, no account — just one optional lifetime purchase for Pro.

TRANSLATION THAT STAYS ON YOUR DEVICE Reading manga in a language you don't speak yet? Penguin Viewer recognizes the text on the page, vertical Japanese included, and lays the translation right over the speech bubbles.

• Runs fully on device, so your pages are never sent anywhere
• Pre-translate a whole book so every page opens already translated
• Download language models ahead of time and translate offline
