LangoVid gets you fluent by watching an endless feed of bite-sized video clips right at your level, so learning feels like scrolling — not studying. No drills, no grammar tables. Watch a 15-second clip, answer a quick quiz, scroll to the next. That's it. The feed keeps rolling — and so does your progress. Learn Spanish, French, Italian, German, Japanese, Korean, Turkish or Hindi — more languages coming soon. THE LANGOVID METHOD — WHY IT WORKS LangoVid is built on comprehensible input. Decades of research point to the same conclusion: we pick up languages through exposure to speech we can actually follow — much the way children absorb their mother tongue — not by memorizing rules and conjugation tables. Every clip features natural, realistic speech in everyday situations. Because you understand what you're watching, the language sinks in on its own — vocabulary, grammar, and pronunciation absorbed in context, one clip at a time. A FEED THAT ADAPTS TO YOU The quick quiz after each clip does more than lock in what you learned — it tells LangoVid exactly what you understand. The feed uses that to keep serving clips in your sweet spot: easy enough to follow, fresh enough to keep you hooked. All videos are AI-generated, which means endless variety — new scenes, voices, topics, and stories every day, tailored to your level and your interests. HOW IT WORKS • Watch a bite-sized clip — around 15 seconds • Read along with subtitles, and tap any word to see what it means • Answer a quick quiz to check your understanding • Swipe to the next one — the feed adapts as you go No prep, no setup, no planning your study session. Just open the app and immerse yourself — LangoVid fits into any spare minute of your day. YOUR VOCAB, FROM YOUR CLIPS Hear a word worth keeping? Save it straight from the subtitles or the quiz. LangoVid turns your saved words into flashcards and brings each one back just before you would forget it, using spaced repetition. Every card is a word you met in a real scene, not on a list. LANGUAGES Spanish, French, Italian, German, Japanese, Korean, Turkish and Hindi, all with subtitles and translations. Japanese clips include furigana, and tapping a word shows its hiragana reading; Korean and Hindi clips show romanized transliterations, so you can follow along from your very first clip. LangoVid also comes in Spanish, Portuguese, French and German, with every translation in that language. FREE TO START Your first clips every day are free. Subscribe for the unlimited feed and keep your streak going. Cancel anytime. Press play. Understand. Get fluent.
