## What is Duck Study?

English vocabulary from the shows and movies you watch.

Name a show or a movie you watch in English. Duck reads its subtitles, finds the words and phrases you don't know yet, and turns them into flashcards at your level. You keep the ones you want and study them a few minutes a day.

LEARN FROM WHAT YOU WATCH
• Search for a show or a movie and add it to your list
• Make cards for the episode you will watch next
• Keep or skip each suggested card, so your deck has only the words you need
• Every card comes with the real line from the scene

STUDY THAT FITS YOUR LEVEL
• Duck finds your level in a short first session and keeps you just above it, where you learn fastest
• Spaced repetition brings each card back at the right time: hard cards sooner, easy cards later
• Two answers only: you know it, or you are still learning it
• Practice for stubborn cards: see the meaning and type the word
• Study your cards without a connection; your progress syncs when you are back online

AN AI TUTOR THAT KNOWS YOUR CARDS
• Ask about any word or phrase and get a short, clear answer
• One tap turns the answer into a card
• Ask the tutor to edit or delete a card, and it waits for your OK
• Paste any text, such as an article or song lyrics, and get its vocabulary as cards
• Get explanations and examples for the card in front of you

YOUR DATA IS YOURS
• No passwords: sign in with a code sent to your email
• Delete your account at any time from Settings
