What Is a Vocabulary Trainer with SRS?

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.

Beats Forgetting

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.

Efficient Learning

Instead of drilling every word equally, the system focuses on the ones you haven't mastered yet – saving you time.

Long-Term Retention

Thanks to gradually growing review intervals, vocabulary moves into long-term memory instead of fading away after the test.

Never Repetitive

Flashcards plus seven question types keep repetition from ever feeling monotonous, training several senses at once.
