Automatic sentence mining: capture from your real life, no manual cards
Automatic sentence mining is when the app captures the sentence and builds the flashcard for you, instead of you hand-typing every card into Anki. TangoLango does it from your real life: photograph a sign, paste a message, or snap a menu, and it becomes a native-audio card, scheduled so you keep it.
- Capture from a photo, a screenshot, or pasted text
- The app picks the i+1 sentence and records the audio
- FSRS scheduling, 24 dialect-pure tracks
Why people want to automate it
Because the method works but the manual part is a chore. Hand-mining a card means reading, looking a word up, copying the sentence, finding audio, and pasting it all into Anki, a couple of minutes each. Do that after a long day abroad and you skip it, and the deck dies. Search "automate sentence mining" and you mostly find dev scripts and corpus miners built for people comfortable in a terminal. What's been missing is a version for your phone that captures the language you actually run into.
What "automatic" actually covers
It depends on where the sentence comes from:
- From video: Migaku overlays Netflix and YouTube subtitles and builds a card in one click, audio and screenshot included. If you learn from shows, it's the slickest option going.
- From a text corpus: open-source miners scan a big pile of text and surface the sentences with just one unknown word. Powerful, but you're wiring up tools.
- From your day: this is the gap. None of the above mines the sentence you actually met at the counter, on the sign, in the group chat. That's the one TangoLango fills.
How TangoLango automates it
You capture the thing that stumped you and the app does the rest:
- Capture. Photograph a sign or a label, screenshot a message, or paste text.
- Mine. TangoLango finds the sentence at your level, one new step past what you know (Krashen's i+1), and checks it against your track's dialect.
- Card. It writes the meaning and records native audio, so you train your ear too.
- Schedule. FSRS brings it back right before you'd forget.
No deck to build, no tabs. Your review pile becomes the exact language your week keeps handing you, in whichever of the 24 tracks you're learning. This is sentence mining with the grind removed, and if you want the tool comparison, here's the best sentence mining app for it. To see how it fits with the other approaches, start with the methods directory.
"The Reddit threads all ask the same thing: can something just mine the sentences for me? That's the whole app. You point your phone at the sign you couldn't read, and it hands you the card."
Frequently asked questions
Can sentence mining be automated?
Yes, in parts. Video tools build a card from a subtitle line in one click, and open-source miners pull good sentences out of a text corpus. What was missing was mining from your actual life. TangoLango captures the sentence from a photo or a pasted message, picks the one at your level, and builds the audio card for you, so the only manual step left is the review.
Is automatic sentence mining as good as doing it by hand?
The learning principle is the same, because the card is still a real i+1 sentence reviewed with spaced repetition. What changes is whether you keep it up. Hand-building cards is where most people quit, so automating that step is usually the difference between a deck you feed daily and one you abandon. You lose a little fine control over each card and gain the habit.
Does automatic sentence mining work from Netflix?
From video, yes, with a tool built for it: Migaku overlays streaming subtitles and clips the audio into a card. TangoLango works from a different source, the language around you in real life (signs, menus, messages), rather than on-screen subtitles. If your main input is shows, use a video miner; if it's your day abroad, that's what we capture.
