Store description excerpt
Yuchang helps non-native English speakers read, say, and draft the English of academic and technical work — with a special strength in mathematical notation. Read equations aloud, fix grammar and word choice, and turn rough phrasing into polished English for papers, talks, and Q&A. Everything runs on your device — no account, no sign-up, and your text never leaves your iPhone. 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. Made by Bon Standard. Apple Intelligence is a trademark of Apple Inc.
