Woordje - Vocabulary Trainer

Learn vocabulary smarter with spaced repetition. Import words from Duolingo, practice with quizzes and flashcards, and track your progress.

Woordje helps you remember vocabulary for any language using FSRS — the same spaced repetition algorithm trusted by millions of Anki users. Import your word list from Duolingo with our free Chrome extension, or add words manually. Then practice daily with smart sessions that adapt to your memory. Words you struggle with come back sooner. Words you know well space out further. Every review is optimised for long-term retention.

HOW IT WORKS Woordje schedules your reviews using the FSRS algorithm, which predicts when you're about to forget a word and brings it back at exactly the right moment. You'll spend less time reviewing and remember more.

PRACTICE YOUR WAY Choose from three exercise types: multiple choice quizzes, tap-to-reveal flashcards, or type-from-memory challenges. Mix them together or focus on one. Practice in both directions — recognise the word or produce it from memory.

TRACK EVERYTHING See your daily streak, estimated CEFR level, vocabulary breakdown, and weekly activity. Every word shows its current recall strength so you know exactly which words need attention.

IMPORT FROM DUOLINGO Install the free woordje Chrome extension to automatically capture your Duolingo vocabulary. Words sync to your account and are ready to practice immediately.
