jidoujisho review
A free Android immersion toolkit for learners mining personal media into AnkiDroid cards.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
jidoujisho is a free, open-source Android application for learners who study through native media rather than a fixed lesson sequence. It brings video and audio playback, subtitle and paragraph dictionary lookups, EPUB and HTMLZ reading, Mokuro manga support, lyrics, sentence mining, and flashcard creation into one toolkit. Its strongest audience is Android learners with personal media libraries who want to turn authentic content into study material, especially those already using AnkiDroid or Japanese-learning resources.
The standout feature is its media-to-flashcard workflow. Learners can look up words from subtitles and paragraphs, capture image and audio context, and export cards to AnkiDroid. The app also supports YouTube closed captions and auto-generated captions, Jellyfin libraries, direct URLs, WebSocket connections for texthookers, and dictionary systems including Yomichan, Migaku, and DSL. Offline EPUB, HTMLZ, and HTML manga reading broadens the input formats beyond video, while optional ChatGPT interaction adds grammar information and examples.
This breadth makes jidoujisho more of an immersion workbench than a conventional language course. Its Android-only platform is a clear constraint, and its published positioning emphasizes input, lookup, reading, and card creation rather than a broad set of structured practice activities. Learners who want control over their own media, dictionaries, and review pipeline should find the open-source model appealing. Those seeking a guided curriculum, wider platform coverage, or a clearly defined catalog of supported languages should choose a more structured alternative.
