ContextVoca

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.
