LangBlitz: Vocabulary Builder

Build an English vocabulary that actually sticks.

LangBlitz is an English vocabulary builder that helps you learn, expand, and remember words for the long term. Discover a Word of the Day, strengthen your vocabulary with smart flashcards and quizzes, and use FSRS-powered spaced repetition to review words when you're most likely to forget them.

Whether you're an ESL learner, preparing for an exam, improving your professional English, or simply expanding your vocabulary, LangBlitz helps you turn new words into lasting knowledge.

Rate a flashcard Again, Hard, Good or Easy, and your review schedule adjusts automatically, so you spend less time on words you already know and more on the ones that need it.

LEARN WORDS, NOT JUST DEFINITIONS
Explore 5,000+ curated words across 119 topic groups, organized by CEFR level from A1 to C2. Every card goes beyond a dictionary entry: definitions, nuance, example sentences for everyday, academic and professional contexts, synonyms, antonyms, collocations, word family, etymology, mnemonics, common mistakes, and adjustable US/UK pronunciation, so you understand how a word is actually used. Take fast-track quizzes to skip levels you already know and start practicing at your preferred CEFR level.

NATIVE-LANGUAGE DEFINITIONS IN 29 LANGUAGES
Learn words more effectively with word definitions in your native language. Short native-language explanations are available for all 5000+ words in:
Arabic, Bengali, Chinese (Simplified), Chinese (Traditional) Dutch, French, German, Gujarati, Hindi, Indonesian, Italian, Japanese, Kannada, Korean, Malay, Malayalam, Marathi, Polish, Portuguese, Romanian, Russian, Spanish, Tagalog, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu, and Vietnamese.
