- Video - mine a video + subtitle pair, with a screenshot and audio clip on every card.
- Audio - mine an audio file + transcript pair.
- Reading - mine manga (mokuro), novels (
.epub, Aozora.txt), or standalone subtitle files. - Settings - everything configurable, with a skippable first-run wizard.
- Animated screenshots - the card image can be a short looping clip of the line instead of a still (off by default).
- Extensive filtering: i+1, frequency limits, blacklist, wordsets, proper-noun name lists, and more.
- Offline Yomitan dictionary import - definitions, pitch accent, frequency - chained by priority.
- Word audio from on-device audio packs - the local-audio-yomichan collection or its generated android.db; sentence audio from your device's Japanese text-to-speech.
- Optional Jisho.org online fallback for definitions (slower, rate-limited).
- Interface translated into 11 languages besides English.
- Light and dark themes from ported palettes - Catppuccin, Dracula, Nord, Gruvbox, Solarized, and more. Android 12+ can take colours from your wallpaper.
How It Works
- Read the subtitles or text and split Japanese into individual words.
- Filter to content words you don't already know.
- Grab a screenshot and audio clip from the video for each line.
- Look up definitions in your configured offline dictionaries, optionally falling back to Jisho online if enabled.
- Send the finished cards to AnkiDroid.
- AnkiDroid installed from the Play Store or F-Droid.
- A 64-bit ARM (
arm64-v8a) device on Android 8.0 (API 26) or newer.
- Install AnkiDroid and open it once.
- Download
anki-miner-android-<version>-arm64-v8a.apkfrom the latest release. - Allow installing from unknown sources, then open the APK to install.

| No definitions found | Add a dictionary in Settings -> Resources, or enable the Jisho fallback (slower, rate-limited). |
| Setup notice on a mining tab | Open Settings and finish the flagged step (tokenizer, dictionary, or AnkiDroid). |
| Sentence audio missing or wrong | Install a Japanese text-to-speech voice in your Android system settings. |
| Word audio missing on cards | Import an audio pack or android.db under Settings -> Resources, and map the expression audio field. |
