Build a vocabulary profile while you study. Mark words as known or learning, explore CEFR levels, pronunciation, examples, preferred-language translations and Deep Dive context, then revisit learning words with spaced review.
Swipe right to archive, left to study, and up to skip. Study hundreds of words frictionlessly.
The algorithm schedules flashcard reviews based on cognitive memory retention curves.
LexUp teaches English vocabulary while letting learners translate English words, definitions and examples into their preferred language.
Scientific studies show that passive reading (rereading lists of words) is one of the least effective ways to learn a language. True learning happens through active recall—forcing your brain to retrieve a word's meaning. LexUp's smart flashcards are designed to trigger active recall every time you study.
Each choice has a purpose. Known words help LexUp understand your current range; learning words enter a focused queue; skipped words can return later. Recommendations become more relevant as the profile develops.
Swipe Right means 'I know this word' to archive it. Swipe Left means 'I want to learn this word' to queue it for spaced repetition reviews. Swipe Up to skip.
Yes. Once a word is marked for learning, the app schedules review sessions at optimized intervals (e.g., 1 day, 3 days, 7 days) to maximize long-term retention.
