LEARN IN YOUR LANGUAGE • The interface and every grammar explanation in 34 languages — including Arabic, Bengali, Chinese (and Cantonese), Czech, Danish, Dutch, Farsi, Finnish, French, German, Greek, Gujarati, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Punjabi, Romanian, Russian, Somali, Spanish, Swedish, Thai, Turkish, Ukrainian, Urdu, Vietnamese — and English. • The example sentences stay in English — because that's the English you're learning to read and write. • Switch language any time from the globe; everything re-translates instantly.

WHAT IT TEACHES • Over 300 English grammar topics — each with a clear definition, right examples, and wrong examples with the mistake explained. • A built-in quiz that draws from what you've studied and re-rolls every time, so practice reinforces rather than repeats. • A guided Learning Path that takes you level by level. • Spaced-repetition Drill — flashcards that resurface at just the right moment to move grammar into long-term memory. • A Today dashboard with a daily streak, a goal, and a "continue where you left off" card.

HEAR IT TOO • Read-aloud narration on titles, definitions and examples in a clear English voice — great for pronunciation and for learners who take more in by ear.

PRIVATE BY DEFAULT • Everything saves on your own device — no account, no tracking, no sign-up. Works offline.
