Flashcards, varied quiz questions, and a smart spaced repetition system (SRS) make sure new words actually stick in your long-term memory. Free. In 8 languages.
A vocabulary trainer helps you practice new words with purpose, instead of reading them once and forgetting them just as fast. SRS stands for Spaced Repetition System – a method for scheduling review that resurfaces each word right as you're about to forget it. The result: less time spent, more words that actually stick. Jaaluu combines SRS with flashcards and seven different question types – built directly into news articles, videos, books, and the AI chat.
Without repetition, your brain drops new words within a few days. SRS steps in right before that happens, resurfacing words at exactly the right moment.
Instead of drilling every word equally, the system focuses on the ones you haven't mastered yet – saving you time.
Thanks to gradually growing review intervals, vocabulary moves into long-term memory instead of fading away after the test.
Flashcards plus seven question types keep repetition from ever feeling monotonous, training several senses at once.
