Gengo.app: Learn Japanese with Manga & OCR Dictionary
Gengo.app lets you read manga and light novels in Japanese while instantly looking up unfamiliar words with a built-in OCR dictionary.
Overview
Gengo.app transforms your favorite Japanese manga and light novels into powerful language-learning resources. By combining a sleek reading experience with an integrated OCR dictionary, it removes the friction of flipping between a reader and a separate dictionary app, letting you stay immersed in the story while still catching every unfamiliar kanji or phrase. Simply import your own image files, folders, or ZIP archives, and the app handles the rest, scanning the text on the page so you can tap and translate on the fly.
Inspired by immersion-based learning philosophies like AJATT and building on the legacy of the Android app Kaku, Gengo.app was created to fill the gap left by the lack of a reliable cross-platform alternative. Rather than grinding through flashcards in isolation, learners can dive straight into native content they actually enjoy, picking up vocabulary and grammar naturally through context. It's a tool built by and for language learners who believe the best way to learn Japanese is by consuming authentic material.
