Translate with your voice, your camera, and your vocabulary notebook — all without sending a single byte to the internet.
Offline Translator is a privacy-first, on-device translator for Traditional Chinese and English, built on Apple's native Translation framework. No account. No ads. No tracking. Nothing leaves your phone.
WHY OFFLINE TRANSLATOR
Most translators ship your most sensitive moments — travel notes, medical phrases, contract clauses — straight to a foreign server. Offline Translator doesn't. Every translation happens on-device, powered by Apple's Neural Engine. Turn your phone to airplane mode and it still works.
FOUR WAYS TO TRANSLATE
1. Text. Type or paste. Character counter, save to vocabulary, copy with one tap.
2. Voice. Hold to speak, release to translate. Haptic feedback guides you.
3. Photo. Point your camera at a menu, sign, or textbook page. Vision OCR extracts the text, then translates on-device.
4. Dictionary / Vocabulary. Save any word or phrase with one tap. Revisit your saved list, grouped by date.
