About

CantonAI

Features
Read full description

Understand Cantonese and express yourself more naturally. Type in Mandarin or Cantonese—or simply speak—and CantonAI turns your words into a two-way translation with pronunciation and Jyutping. Then ask the AI Cantonese tutor about that exact sentence to understand tone, usage, and context instead of stopping at a literal translation. SAY IT THE RIGHT WAY • Translate between Mandarin Chinese and Cantonese • Choose a natural, polite, or formal tone • Adapt wording for friends, elders, work, travel, or everyday conversation • Explore alternative wording, literal meaning, usage notes, and useful terms TALK FACE TO FACE • Hold the Mandarin or Cantonese button to speak • Recognize, translate, and read the result aloud • Correct an inaccurate transcript and translate it again • Replay either side whenever you need to listen again TURN TRANSLATIONS INTO LEARNING • Ask the AI tutor questions with the current translation supplied as context • Check whether a sentence sounds natural, polite, or right for the situation • Learn Jyutping, tones, everyday slang, and differences in usage • Add a useful translation to My Phrases with one tap • Listen, review, and mark phrases as mastered TRANSLATE TEXT AROUND YOU Use the camera to recognize short text on menus, signs, and other everyday materials, then view its translation. Text recognition happens on the device. Recognized text is used for AI translation only after you give permission. BUILD A PRACTICAL HABIT Daily tasks, tone practice, a daily expression, and a learning streak help turn occasional lookups into lasting progress. Translation history keeps the latest 30 items, while important phrases can be saved for later review. Continue with a stable device-bound guest identity or use Sign in with Apple to synchronize history, favorites, progress, and settings. Camera, microphone, and speech recognition permissions are requested only when you use the related feature.
