The language app for people who'd rather be watching

There is so much to entdecken

Click any word in the subtitles of what you're already watching. VOX saves it with the audio, the scene, and the sentence — and brings it back as a flashcard until it's yours.

When “one more episode” counts as studying

Watch as usual. Click what's new. Review it tomorrow.

While you watch

Subtitles become clickable

The extension shows dual subtitles: the show's line and yours below it. Click a word and its meaning in that sentence appears right over the scene.

One click

The moment is captured

Word, audio around it, scene thumbnail, full sentence, all saved without pausing the show.

Tomorrow

It comes back as a card

Five minutes of review with the exact scene it came from. Easy words fade out; hard ones return sooner.

35+ languagesFrom German and Japanese to Tamil and Ukrainian. Subtitles, books, and explanations follow your pick.
6 platformsWatch what you love and keep the words: every subtitle is clickable, every click is saved.
7 days freeFull access from the moment you start it, no card required. The trial simply ends if you don't subscribe.

Not watching? Read.

Upload an EPUB, PDF, or text file and read it in the built-in reader. Tap any word to see what it means, or translate the whole sentence in place, and save it with its sentence. Your position follows you across devices.

Every article is a lesson

One click puts any page into reader mode: its words become clickable, exactly like subtitles, and a whole sentence translates right under itself when one word isn't the problem. Words you save while browsing join the same deck.

Stuck on a word mid-article?

Right-click it anywhere on the web and choose Explain word. You get a plain-language breakdown on the spot, and the word joins your dictionary with the sentence you found it in.

Does it work with my own books?
