Service Client de Yuchang: Academic English

READ EQUATIONS ALOUD
• Paste LaTeX or type an equation and Yuchang reads it back in natural spoken English — "the integral from zero to one of x squared with respect to x."
• Covers the notation that's hard to verbalize: fractions, integrals, sums, limits, matrices, Greek letters, superscripts and subscripts.
• Tap to listen, then practice your own pronunciation and compare.

TIDY UP YOUR DRAFT
• The Syntax Checker rewrites rough sentences into clear, formal academic English — fixing grammar and stiff word choice — and shows exactly what it changed.
• Works fully offline with a built-in rule engine, and adds on-device AI for more detailed suggestions on Apple Intelligence devices.
• Input is screened for appropriate content and is never sent to a server.

FIND THE RIGHT PHRASING
• Academic Phrases — a library of English phrasing for proofs, definitions, and arguments to start from.
• Presentation Phrases — turn rough phrasing in your own language into polished English for talks and Q&A. Requires Apple Intelligence.
• Glossary — look up mathematical terms with meanings in your language and English pronunciation.

WHAT NEEDS APPLE INTELLIGENCE
• Presentation Phrases requires Apple Intelligence (iPhone 15 Pro and newer, iOS 26 and later) — it has no offline mode.
• The Syntax Checker works offline with its rule engine and adds Apple Intelligence for richer suggestions when available.
• Equation Reader, Academic Phrases, and Glossary work on any supported device — no AI required.
• When AI is used, it runs entirely on-device: no model download, no network calls — so it keeps working with no signal, even on a flight.

SPEAKS YOUR LANGUAGE
• Interface and explanations in English, Korean, Japanese, Simplified Chinese, Traditional Chinese, and Spanish.

PRIVACY-FIRST
• No account. No tracking. No analytics. Data Not Collected.
• Works offline, even in airplane mode.
