LangBlitz: Vocabulary Builder

Learning new words is easy. Remembering them weeks later is the hard part.

LangBlitz helps you build a real, lasting English vocabulary, whether you're preparing for an exam, sharpening your professional English, or simply want to remember more of what you read.

LangBlitz uses FSRS, a spaced repetition method that times each review to help you remember words for longer, based on how well you actually remember them rather than a fixed schedule. Rate a card 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.
