What jidoujisho is
jidoujisho is an Android language-learning toolkit that combines video playback, reading, dictionary lookups, and flashcard creation. It can play local media, YouTube videos, Jellyfin streams, and direct URLs. Users can tap or drag over subtitles or paragraphs to look up words, and read books offline with its embedded ッツ Ebook Reader or manga processed with Mokuro. Flashcards can be exported to AnkiDroid with the current image and audio, with fields editable before export; AnkiDroid is also required for installation. The app supports Yomichan, Migaku, and ABBYY Lingvo DSL dictionaries, but does not include dictionary data, and structured-content Yomichan dictionaries are unsupported. It officially supports Japanese and English; other languages depend on dictionary format and search support. Installation requires Android 7.0 or later and uses an APK selected for the device’s architecture. The free, open-source project does not have an iOS version. It does not host media, and image-based PGS subtitles are unsupported.
