Multilingual Magic

This is the opening of Chaplin's iconic speech from The Great Dictator—written in a mashup of Spanish, German, French, Chinese, Japanese, Korean, Arabic, Italian, Hindi, Russian, and Portuguese. Let's see how the Multilingual Translation prompt handles it:

Give it a shot: Lo siento, Aber ich möchte kein Kaiser sein. Ce n'est pas mon affaire. 我不想统治或征服任何人。私はすべての人を助けたいと思います - 가능하다면 - يهودي, غير يهودي - أسود - أبيض. Tutti vogliamo aiutarci a vicenda. इंसान ऐसे ही होते हैं. Мы хотим жить счастьем друг друга - não pela miséria uns dos outros.

📖 4. Vocabulary Builder

Learn new words, review them regularly, and make them stick for good.

Step 1
