About Prep Vocab
Learn English and Chinese the way they should be learned —
fast, smart, and built for real practice.
Prep Vocab is your AI-powered companion to learn English and
Mandarin Chinese, prep for exams like HSK, IELTS, TOEIC and
TOEFL, and build a daily study habit that actually sticks.
1. SCAN ANY NOTE → AUTO FLASHCARDS
Snap a photo of your textbook, notebook, or screen. Prep
Vocab's OCR engine recognizes English words and Chinese Hanzi
instantly and turns each one into a rich flashcard with
pronunciation (IPA or pinyin), meaning, audio, and example
sentences. No more retyping vocabulary by hand.
2. SPACED REPETITION
Prep Vocab learns which words you forget and brings them back
at the perfect moment — in either language, in one daily
review.
3. INSTANT AI PRONUNCIATION SCORING & FEEDBACK
Our AI breaks down every syllable — English stress and vowel
sounds, Chinese tones. See exactly which sound you got wrong,
why, and how to fix it. Real-time, syllable-level feedback.
Build a daily habit you can keep.
WHO IS THIS FOR
• Learners preparing for HSK 1–9, IELTS, TOEIC, or TOEFL
• Beginners building English or Chinese vocabulary from scratch
• Intermediate learners breaking through plateaus
• Bilingual learners studying both languages side by side
• Self-studiers who want their AI tutor in their pocket
• Anyone tired of static flashcards and gamified taps that
don't translate to real language skill
Start free. Learn every day with Prep Vocab. Pass your exams
confidently.
