2026-08-19 — The classroom on a phone, the tutor in your language, covers on the shelf
The tutor replies in your language. Switch the site to 繁體中文（香港）, 繁體中文（台灣）or 简体中文 and the tutor answers in that register from the next turn, giving each technical term with the English in brackets the first time. Earlier turns stay as they were spoken.
Tell the tutor how you like to be taught. On the account page, pick up to three presets — the examples that land for you, and the way you like to be taught. The tutor reads them before every lesson.
Select any passage — in a chapter or in the tutor's message — to highlight it, ask the tutor about it, or have it translated or explained. Highlights are kept on this device.
One book page for reading and learning. Open a book from the shelf: its chapters are there to read, and, when you are signed in, to start, continue or restart a lesson.
The classroom fits a phone. One scroll for the conversation, a send button at the end of the field, and a light-bulb on the tutor's message when you want the answer shown — still one tap, still recorded honestly.
Books have covers, and the shelf follows the loop. Books · Learn · Cards · Approach · About · Account, and Feedback and What's new in the footer.
One live conversation per chapter. Coming back to a chapter continues where you were; Restart closes it and begins again — what you learned and your cards are kept.
Switching language keeps your lesson open. It used to land on an empty page.
The privacy policy and terms read in Chinese — three registers, with the English as the governing text.
