Learn vocabulary. Remember forever. Fluenzi helps you build vocabulary with structured, CEFR-aligned word lists organized by language level. Start with the foundations at A1 and work your way through increasingly advanced vocabulary. Instead of simply studying word lists, you actively practice what you're learning. Use smart flashcards, match words with their translations, train your listening, practice dictation, and revisit vocabulary through spaced repetition. Vocabulary for your level Fluenzi's vocabulary is organized around the CEFR levels used for language learning across Europe, making it easier to focus on words appropriate to where you are now โ€” and see where you're heading next. Choose your language and level, then let Fluenzi turn that vocabulary into daily practice. Practice in different ways Use smart flashcards for active recall, train your listening skills, practice dictation, or challenge yourself to match words with their translations. Different exercises help you recognize and recall vocabulary from different angles. Remember what you learn Fluenzi uses spaced repetition to bring words back when they need your attention. Words you know well appear less often, while words that need more practice keep coming back. Learn by listening Listening Practice plays words in the language you're learning and asks you to translate them. Dictation Practice goes a step further: listen carefully and type exactly what you hear. You can also slow down pronunciation or hear a word again. Make the connection Matching Practice gives you a quick, visual way to connect words with their translations. Find the pairs, clear the board and keep going. Follow your progress See how much you've practiced, how accurately you're answering, and how your learning develops over time. Streaks and XP give you a little extra motivation to keep going. Designed for focused learning Fluenzi keeps the experience simple and puts practice first. Your learning history and preferences stay on your device, and you don't need an account to start learning. Whether you're starting a new language or expanding vocabulary you already know, Fluenzi gives you several ways to practice โ€” and a reason to come back tomorrow.
