Nuance Translator

Nuance (ニュアンス) is a translation app for Japanese, Korean, Chinese, and Thai that focuses on meaning and tone rather than simply swapping words. In these languages, the right expression depends heavily on who is speaking, who is listening and the situation, and the same sentence can come across as warm or cold, polite or rude.

Nuance lets you choose a mood on its Emotion Dial, such as friendly, respectful, apologetic, thankful, or excited, and rewrites the translation so that feeling comes through in the target language. You can also describe the speaker and listener, including gender, age, and relationship, along with the setting (business, social, medical, romantic, and more) and the format, from speech and chat to email or a formal letter.

Using all of this, the app judges the time, place, and occasion (TPO) of your message and picks a suitable register and level of politeness before you send it. It is free to download and useful for travellers, students, and anyone communicating across Asian languages.
