## A1-C1 Description
Master English vocabulary that sticks.

Key Features:
• Smart flashcards with spaced repetition technology: review intervals adjust automatically based on your mastery of each word.
• Personalized daily texts that match your level and incorporate recently learned words, reinforcing vocabulary in natural contexts for correct conversational usage.
• Option to learn American or British English variants.


Why Our Method Works

Your brain learns best through active engagement and spaced reinforcement. Our app is built on scientifically validated principles:

• Spaced Repetition System: Our algorithm schedules flashcard reviews at increasing intervals, precisely when you need them to combat memory decay and boost long-term retention. Studies confirm this dramatically outperforms cramming.

• Active Recall: Forget passive rereading. Flashcards force your brain to actively retrieve information, strengthening neural pathways far more effectively. This is a powerful memory enhancer.

• AI-Powered Contextual Learning: Memorizing definitions isn't enough. Our AI generates daily personalized dialogues featuring the words you struggle with most, tailored to your proficiency. Encountering words in varied, meaningful contexts deepens understanding and makes them truly memorable.
