What jidoujisho is
jidoujisho is a free, open-source Android toolkit for language immersion that combines video playback, reading, dictionary lookups and flashcard creation. It plays local media, YouTube videos, Jellyfin streams and direct URLs. While viewing subtitles or reading paragraphs, users can tap or drag across text to look up words in dictionaries. The app supports offline books through its embedded ッツ Ebook Reader and manga processed with Mokuro. Users can edit flashcard fields before exporting cards, including the current image and audio, to AnkiDroid. The app works with Yomichan, Migaku and ABBYY Lingvo DSL dictionary formats, but does not include dictionary data; Yomichan dictionaries using structured-content are not supported. Other listed services include ChatGPT, Bing image search, Forvo, JapanesePod101 audio search, and example sentences from Massif, Tatoeba and ImmersionKit. Japanese and English are officially supported. Installation requires Android 7.0 or above and AnkiDroid. The project is released under the GNU General Public License 3.0.
