LinguaMiner
Learn languages from the videos you love
Turn the videos you already watch into Anki flashcards. Everything runs on your own machine — no accounts, no subscriptions, no API keys, and nothing you watch is ever uploaded anywhere.
You open a video — a local file, a YouTube link or an HLS stream — and it plays with word-by-word clickable subtitles. Click a word you don’t know and you get its lemma, part of speech, dictionary senses and how common it is. Keep it, and an Anki card is built for you: the sentence audio trimmed with ffmpeg, a short animated clip of that exact moment, and the sentence with a translation.

Start here
- Installing LinguaMiner, step by step — written for people who have never opened a terminal.
- How to use it — every feature, in the order you meet them.
- Adding a language — what has to exist for a language to work, and where each candidate currently stands.
Or run it with Docker
No installer, no Python — one command, then open http://localhost:8977:
docker run -d --name linguaminer -p 127.0.0.1:8977:8977 \
-v linguaminer-data:/data --add-host=host.docker.internal:host-gateway \
ghcr.io/thecopybookhare-cmd/lingua-miner:latest
Details — Anki from inside the container, your own videos, updating — are in the README.
What else it does
- Word states synced from Anki. Red is new, orange is learning, unmarked is known — read back from your actual review intervals. A chip tells you what percentage of the video you already understand.
- i+1 recommendations. A word lights up only when it’s unknown, frequent enough to be worth your time, and not a proper noun.
- Bring the vocabulary you already have from Migaku, jpdb, LingQ or an Anki deck, so those words don’t start out red.
- Read books too. Import a
.txtor.epuband you get the same clickable words, the same popup, and cards read aloud by Piper. - Condensed audio. Export an MP3 with only the dialogue of an episode — a 50-minute show becomes about 20 — for passive listening.
- Your own dictionaries, including Yomitan format.
Thirteen languages
Catalan, Spanish, French, English, German, European Portuguese, Italian, Dutch, Russian, Mandarin Chinese, Cantonese, Japanese and Korean — translating into Spanish or English. Learning Spanish? RTVE Play, Spain’s free public streaming service, works straight from Watch online, subtitles included.
Transcription is Whisper, translation is CTranslate2 (OPUS-MT, or NLLB-200 for pairs OPUS doesn’t cover), speech is Piper. Each language downloads its own models the first time you use it.
