Binge videos in another language. Walk away with the vocabulary.

You lose hundreds of words and phrases from videos you watch. Yuki pulls out what's worth keeping, matches it to your level, and turns it into flashcards you'll actually review.

How it works

1. Paste a link or text

Drop a YouTube link or any text in a language you're learning. Tap recognize — Yuki does the rest.

2. Pick the words you need

Yuki extracts words and phrases matched to your level. All are selected by default — just remove what you already know and add the rest to any deck.

3. Review and remember

Yuki schedules flashcard reviews using spaced repetition. Words come back right before you forget them.
