Build the English vocabulary you actually use — your way.
WordStudy turns anything you read or watch into study material, then helps every word stick. Add words the way that fits you, practice at the intensity you're in the mood for, and grow your English one word at a time.
ADD WORDS FROM ANYWHERE
• Paste a YouTube link — get the new words from the subtitles, filtered by your CEFR level
• Paste any text — an article, a chapter, song lyrics
• Snap a photo — book pages, menus, signs
• Pick from 40 themed collections — IELTS, Business, Travel, Phrasal Verbs, Idioms, Modern Slang and more
• Or add a word by hand
84,633 English words are recognised instantly — each with a translation in your language, a CEFR level (A1–C2), a definition, example sentences, and pronunciation audio ready to learn. The interface is available in 18 languages.
PRACTICE YOUR WAY
Not every session needs the same effort:
• Full cycle — 4 exercises back to back (flashcards, quiz, matching, spelling) to lock a word in
• A quick single exercise — including practicing a word inside a real sentence, or finding its synonyms
• A light game — swipe through words, match pairs, find words in a grid, or solve a crossword built from your own words
• Home-screen widgets — a word a day or a full practice session, right from your home screen
Three levels of effort. You choose.
ON YOUR TERMS
• Reminders when you choose — daily, specific days, your own time
• Revisit learned words whenever you want
• Gentle spaced repetition quietly backs you up — learn at your own pace
• Works offline, syncs across your devices
WHY VOCABULARY
Your vocabulary is your English. Roughly 2,500 words let you follow everyday conversation, 4,000 cover most TV, and 8,000+ get you thinking in English. WordStudy sorts words by CEFR difficulty, so you learn what's one step above you — not random hard words you'll forget.
Great for building toward IELTS, TOEFL, CAE, work English, or just understanding the videos you love.
