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.
