Linglass turns YouTube into the most natural way to learn a language — watch what you love, with dual subtitles, and pick up words without it ever feeling like studying. Tap any word in the subtitles to see what it means in context (not just a dictionary definition), hear it pronounced by a native voice, and save it with one tap. Every saved word comes back at the perfect moment with spaced-repetition flashcards, so it sticks. DUAL SUBTITLES ON YOUTUBE Watch any YouTube video with subtitles in your target language and your own, side by side. Tap a word for an instant, context-aware translation. CONTEXTUAL TRANSLATION + PRONUNCIATION Get the meaning that fits the sentence, with phonetic transcription and native-voice audio. Built for understanding, not just lookups. AI GRAMMAR EXPLANATION Select a sentence and get a clear, structured breakdown of the grammar — each construction labelled with its CEFR / JLPT / HSK / TOPIK level, in your own language. SMART FLASHCARDS (SPACED REPETITION) Review saved words with the real video context — the sentence and the frame they came from. The FSRS algorithm schedules each card right before you'd forget it. TRACK YOUR PROGRESS Streaks, a review heatmap and clear stats keep you coming back. LEARN: English, Spanish, French, German, Italian, Portuguese, Russian, Japanese, Korean and Chinese — with the interface in 20 languages. FREE TO USE: 15 translations a day, 50 saved words, and AI grammar explanations every month. PREMIUM removes the limits — unlimited translations, unlimited saved words and far more AI grammar — with a 7-day free trial. Watch. Click. Translate.

Words in English, Japanese and Chinese show their level too. Along the way we fixed several bugs, including one where removing a saved word took an extra tap.
