Subtitles that meet you where you are.

I swap a few words of each line into the language you’re learning. Swipe the subtitles for more or fewer, right up to the whole line.

NewHeardKnownYou can say itYou can use it

Ask about any line, or any word.

Point at a word for its meaning and reading. Ask me why she said it like that, and I’ll answer with the scene in mind.

Say it out loud. I’m listening.

Talk to me by voice, right over the video. Say a line back and I’ll help with your pronunciation and tone.

Flashcards, made from your shows.

Save a word and I’ll make it a card, with the line and the scene it came from. I bring it back right before you’d forget.

A quick question when a scene ends.

When a scene ends, the subtitles glow. Click them for one quick question about what you just watched. Answer it to keep your streak, or skip it.

Five minutes a day. Watch yourself improve.

A short session made from what you watched: a line to say back, your cards, one challenge. Watch your words climb, as you start understanding more and more of the shows you watch.

Your next episode could teach you something.

We’ll email you when Duet is ready. Nothing else.
