Each question is spoken by that person — listening, speaking, sentence building and real conversation, a little every day. ■ Four languages English, Spanish, Chinese and Japanese. Choose the one you want and the course is assembled in it. ■ A course built from the people you chose Historical figures and classic literature. The names you pick become the order of your level-by-level curriculum. ■ Lessons in their own voice Every question comes from that person, and each correct answer is praised in your native language. ■ Talk with them Speak and listen as if you were on a call. (The conversation is an AI re-creation, not a real statement by that person.) ■ A little every day One more round today and a daily streak keep the habit small enough to keep. ■ Plus subscription Learn as much as you want, with no heart limit. Everyone in the app is a public-domain historical figure or a character from classic literature. Admiration is the best teacher. Start today.
