About this app



Unlock a new language by using the apps you already love, every single day. Our unique approach helps you learn naturally by immersing you in your favorite content on YouTube, Spotify, and more.



Learn Any Language, From Any Language


Our most powerful feature: you are not limited to learning from English. You can learn any language from your own native language. Imagine learning Japanese from a video in German, or learning French with subtitles in Spanish. Your language journey is truly yours. This makes it easy to:



  • Learn Korean from English

  • Learn Spanish from Hindi

  • Learn Japanese from German

  • Learn English from Spanish

  • Learn French from Arabic

  • ...and any other combination you can imagine!



A Revolutionary Way to Learn with Video


Our learning experience works directly on top of the YouTube app.



  • Dual Language Subtitles: Watch any video with subtitles in two languages simultaneously. Follow along with the original audio and see the translation in real-time.

  • Learn from Your Native Language: Watch a video in your own native language, and our app will intelligently highlight important idioms, expressions, and hard words, showing you how they are used in the language you want to learn! You build vocabulary from content you already understand perfectly.



Immersive On-Screen Learning


Your learning doesn't stop with video.



  • On-Screen Magnifier: Drag our floating magnifier over any text in any app—a game, a blog, or a social media feed—to get an instant translation and identify key vocabulary. It's the only on screen translator you'll ever need.

  • Floating Lyrics: Turn your music session into a study session. See synchronized, translated lyrics float over any music app.



Your Smart Vocabulary Engine


When you discover a new word or phrase, simply add it to your personal Leitner-based vocabulary box.



  • Master Your Vocabulary: Our smart review system helps you master these words without being annoying. It gently reminds you with floating flashcards at the right moments, while you're using other apps. It's highly effective, and it never interrupts your flow.
