•  Use card creator mode to quickly search images and definitions with imported photos and text

 Current state of the project

jidoujisho is still in development, and is currently in hiatus. The project will receive fixes to critical bugs and issues. Rollout of new features will resume in time.

Built for the Japanese language learning community, the application is free and open source software, and is available to download here on GitHub. Current features planned on the roadmap are listed below, but as of now there is no estimate on any updates.

Please note that the development of the app switches between changes being implemented and being left alone for daily use. Update frequency may depend on the gravity of any issues that arise. Hiatuses provide practical insight on usage and where development should go next.

 Next Up

•  Fixes for slow video loading due to scoped storage and H.265 video playback
•  Use of the AnkiDroid API instead of share intent to streamline card export and Anki output customisation
•  Morphological analysis of subtitles for better text selection
•  Improved monolingual dictionary support
•  Various immersion modes for oral practice
•  Include pitch accent information in dictionary and exported cards
•  Reader enhancements for manga and novel sentence mining
•  Instant queries and offline use via support of Yomichan archive format dictionaries
•  Improve text segmentation and custom dictionaries query results
•  Dedicated Android TV experience with a remote control
•  HTML summary tags for dual query mode

 Stretch Goals

•  Extensive language support with text segmentation for other languages
•  Tinker around with releasing the app on other platforms if possible

 Using the application

 Supported Formats

jidoujisho will take video and audio formats as supported by VLC. Subtitles may be embedded within the video being played and selected during playback.

If you wish to use external subtitles, they may be in SRT, ASS or SSA format and you may import them during playback through the menu. You may switch between different audio and subtitle tracks. Image-based subtitles such as PGS are not currently supported.

YouTube closed captions are taken from TimedText XML, which is only publicly exposed to videos that have user-generated Japanese subtitles. Here is a fair sample of YouTube videos with such subtitles showcasing some very practical application use cases. If unavailable, Japanese automatic captions can be queried from videos. Please be aware that critical inaccuracies are to be expected in such cases.

A primer on the basics of the application is as follows.

•  Download and install the latest beta onto your Android device
•  Watch a video with the Player selecting from your local media library or picking a YouTube video
•  Start a novel with the Reader to launch ッツ Ebook Reader to read an EPUB or HTMLZ file
•  Read manga from your Tachiyomi library with the Viewer and launch Kaku to pass text to the app
•  Select text with tap to select or drag to select
•  When the dictionary definition for the text shows up, the text is the current context
•  Closing the dictionary prompt will clear the clipboard
•  Switch between dictionaries by holding on the headword or swiping vertically in the pop-up dictionary
•  You may swipe vertically to open the transcript in the player, and pick a time or read subtitles
•  Swipe horizontally in the player to repeat the current subtitle audio
•  Swipe left or right on dictionary results to scroll through multiple definitions
•  In the Viewer, users can pass text to the app by holding onto Kaku‘s results box

 Exporting to AnkiDroid

•  You may also export the current context to an AnkiDroid card, including the current frame and audio
•  Having a word in the clipboard will include the sentence, word, meaning and reading in the export
•  You may edit the sentence, word, meaning and reading text fields before exporting to AnkiDroid
•  The front of the card will include only the sentence
•  The back of the card will include the audio, image, reading, word and meaning
•  You may apply text formatting to the card with the AnkiDroid editor once exported
•  Customisation of the Anki export is possible by changing the default template in AnkiDroid

 Advanced User Tips

•  If your subtitles are off, you can set the delay or pad the exported audio time with an allowance
•  A resume button is at the top of the main menu, and returns to last video or book
•  Users may select Context from a dictionary result to go back to the exact duration in video or scroll position in book
