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\nPoint 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.
