About OpenQuiz AI: Vocabulary Quiz
Memorise the words, then say them — in any of 50+ languages. OpenQuiz AI turns a photo of your textbook into flashcards, schedules your reviews with spaced repetition, and lets you practise real conversations with an AI that scores your pronunciation.
BUILT FOR EXAM CANDIDATES
• IELTS Speaking: Parts 1–3 with an AI examiner, band-style feedback and model answers
• TOEIC, TOEFL, PTE and Cambridge vocabulary: create sets from your own materials or study shared ones
• JLPT N5–N1, HSK 1–6 and TOPIK I–II: exam-tagged word sets with a review plan that fits your test date
• School exams: paste the word list, get flashcards, dictation and quizzes in seconds
HOW IT WORKS
1. CREATE — photograph a page, paste text or type a list. AI adds meanings, example sentences, pictures and native audio.
2. MEMORISE — flashcards, dictation, fill-in-the-blank, quizzes and games, timed by spaced repetition so you review just before you forget.
3. SPEAK — start an AI Call on any topic. The AI uses your new words, corrects your grammar, scores your pronunciation, and a coach mode guides you phrase by phrase.
LEARN ANY LANGUAGE
English, Japanese, Korean, Chinese, Spanish, French, German and 50+ more — with definitions in your own language.
