Add words from YouTube, any text, or 40 collections. Then practice your way: a full 4-step cycle, a cycle you build yourself, a quick exercise, or a relaxed game. Either way, words stick.
Three of the five import paths previewed below. Each one filters by CEFR level, skips words you already learned, and shows you exactly what's new, powered by a CEFR-tagged dictionary of 84,633 English words with translation and definition, ready to learn.
This recipe needs only five ingredients. Mix the flour with the eggs until the mixture is smooth, then bake for forty minutes. Serve each slice warm.

40 topics, and every word already has a translation and a level. Tap a collection to look inside.
Take the level test to see where you are, or jump straight into a collection that catches your eye.
Collections, YouTube subtitles, pasted text, camera scan, or just typing. Whatever fits the moment.
Cards → quiz → matching → spelling. Then take it further: a word in a real sentence, synonyms, irregular and phrasal verbs, or a quick word game. The algorithm decides when each word comes back.
Roughly: 2,500 words = follow daily conversation. 4,000 = understand most TV. 8,000+ = think in English. Every mastered word is a step.

WordStudy is a vocabulary builder rather than a beginner course, and it works at every level from A1 to C2. Just starting out? Use translation mode and the starter collections. Already reading comfortably? Switch to English-only definitions and go after the harder words. It fits whether you're preparing for IELTS or TOEFL, working in English, or simply want to read and watch more freely.
Three things. First, words you've mastered stay mastered, with no surprise repetitions. Second, a bonus Context exercise lets you practice each word inside a real sentence, not just in isolation. Third, five different ways to add words, so whatever you're reading or watching becomes study material.
Every one of the 84,633 words has its own level, from A1 (beginner) to C2 (proficient). When you import a video or a text, only the words above your current level are kept, so you never wade through vocabulary you already have.
Yes, five ways. Pick from 40 themed collections, paste a YouTube link to extract subtitles, paste any text, scan with your camera, or just type words manually. All flow into the same study queue.
No. When you finish a word through the 4-step cycle, it's marked mastered and leaves the review queue permanently. You'll only see it again if you choose to look it up.
Paste any YouTube URL. The app reads the subtitles, filters out words below your level, and gives you only the new vocabulary worth learning. Works with TED talks, interviews, documentaries, podcasts with captions.
After the 4-step cycle (flashcards, quiz, matching, spelling), Context is a bonus exercise: you see a real example sentence with the word missing, and you fill it in. That's how a word goes from «I recognise this» to «I can use this».
Yes. Free tier: 4 collections, 100 YouTube words per month, the level test, the full 4-step cycle and word games, and 2 free tries of every Premium exercise. No card required.
$99 one-time. All 40 collections, unlimited imports, all 15 exercises and games, your own exercise cycles, all CEFR levels, and every future update. No subscription, nothing to renew.
Yes. The dictionary and your word list live on your device. Daily study works without internet. Sync runs in the background when you reconnect.
Monthly and annual subscriptions cancel from your Apple ID or Google Play settings. Lifetime is a one-time purchase, so there is nothing to cancel.
Either in-app (Profile → Settings → Delete account) or via wordsstudy.com/delete-account. Both wipe your data permanently.
WordStudy is built for exactly this: paste any YouTube link and it extracts the subtitles, filters out words below your level, and turns the new vocabulary into study cards. Each word arrives with a translation, CEFR level and definition from a dictionary of 84,633 English words. A vocabulary builder for every level, free on iOS and Android.
WordStudy uses spaced repetition with one difference: once you master a word through its 4-step cycle (flashcards, quiz, matching, spelling), it stays mastered, with no surprise repetitions. If you start forgetting one, the app brings it back. A bonus Context exercise has you use each word in a real sentence, moving it from «recognise» to «can use».
WordStudy suits exam prep because it targets vocabulary growth at whatever level you're on right now: take the level test, then add words from 40 themed collections, YouTube, pasted text, or a camera scan. Every word is CEFR-tagged (A1–C2) so you focus on the band you need. The free tier covers the level test and starter collections; no card required.
Roughly: ~2,500 words to follow daily conversation, ~4,000 to understand most TV, and 8,000+ to think in English. WordStudy grows that vocabulary at your pace, from anything you read or watch, with a CEFR-tagged dictionary of 84,633 words.
You pick the meaning you actually met. 7,646 words in the dictionary carry more than one translation, and each one is labelled with the sense it belongs to — pitch, for instance, is a sports field, the height of a sound, and a sales talk. Add a word like that and WordStudy shows you the options instead of silently taking the first. This works in all 17 translation languages.
Different jobs. Duolingo teaches a course from scratch; Anki is manual flashcards you build yourself; WordStudy grows your vocabulary fast from your own sources: YouTube, text, books, or 40 ready collections. Every word arrives pre-loaded with translation, definition and CEFR level, so there's no manual card-making.
Free to start. 5 minutes to add your first 20 words and try all the exercises.
