ContextVoca uses AI to turn photos and text into your personal vocabulary list — then quizzes you until you own those words. [SNAP - LEARN - REMEMBER] Point your camera at a book, menu, sign, or any text. Our OCR engine reads it, and our AI extracts the vocabulary words most worth learning. No more manual lookup — just learn. [AI-POWERED WORD EXTRACTION] ContextVoca's LLM engine analyzes your captured text and selects the most meaningful words for your level. It strips away common words and surfaces the ones that will expand your vocabulary fastest. [SMART QUIZ SYSTEM] Our adaptive quiz engine schedules reviews based on how well you know each word. The more you struggle with a word, the more often it appears — so you never forget what you've worked hard to learn. [CONTEXT-BASED LEARNING] Every word is stored with the sentence or phrase it came from. Seeing a word in context is proven to dramatically improve retention compared to isolated flashcards. [KEY FEATURES] - OCR text recognition from photos and camera - AI keyword extraction - Spaced repetition quiz (multiple choice + fill-in) - Context sentences saved with every word - Vocabulary statistics and learning streaks - Word tagging and custom categories - Available in English, Korean, Japanese, and Chinese [SUBSCRIPTION PLANS] - Free — up to 100 words, core features - Basic — up to 1,000 words, all features (monthly or yearly auto-renewing subscription) - Pro — unlimited words, all features, priority support (monthly or yearly auto-renewing subscription) Prices are shown on the in-app subscription screen.

영어 공부 오래 했는데 실제 영어는 왜 안 들릴까요? 단어를 몰라서가 아닙니다. 실제 대화에서는 단어를 또박또박 읽지 않고 뭉쳐서(연음) 말하기 때문이에요. "Where are you?" → 실제로는 "워이유?" "What did I?" → "워르라이?" "Is that a?" → "이재러?" Cantok은 이 '연음'을 귀로 직접 풀어내는 훈련을 합니다. ■ 아하 카드 — 연음이 들리는 순간 들어보기 → 맞춰보기 → 아하! → 모핑 → 확인. 5단계를 거치며 뭉쳐 들리던 소리가 또렷한 문장으로 바뀌는 '아하 순간'을 경험하세요. ■ 받아쓰기 — 진짜 들리는지 확인 들리는 소리 그대로 단어를 순서대로 맞춰보세요. 비슷하게 들리는 함정 보기까지, 끝까지 들어야 풀립니다. ■ 연음 퀴즈 — 처음 보는 문장에서 확인 배운 소리를 한 번도 안 본 문장에서 다시 만나요. 연음 152종 전부, 1,064문항 · 전 문항 음성 수록. ■ 쉐도잉 & 통역 — 듣고 따라 말하기 문장을 듣고 따라 말하면 단어별로 체크해줘요. 한국어를 영어로 바꿔 말하는 통역 모드까지. 따라 말한 뒤에는 두 소리를 파형으로 나란히 볼 수 있어요 — 어디가 길고 짧은지 눈으로 확인해요. ■ 패턴 학습 실생활에서 바로 쓰는 표현 패턴을 반복으로 익혀요. ■ 이런 분께 · 듣기만 하면 막히는 분 · 자막 없으면 영화·미드가 안 들리는 분 · 단어는 아는데 회화가 안 되는 분 설치 후 14일은 전 기능을 무제한으로 무료 이용할 수 있어요. 체험이 끝나도 연음·아하 카드는 매일 무료로 제공되며, 더 많이 학습하려면 프리미엄으로 무제한 이용할 수 있습니다. 지금, 안 들리던 그 소리를 들어보세요. ※ 앱 내 음성은 AI 음성으로 제작되었습니다. 이용약관(EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
