Travellers in Korea are surrounded by signs, menus and notices they cannot read. A translation app turns the letters into words, but standing in front of a sign you need more: why is it here, and what should I do now?

Nunchi is a mobile web app that answers that. Take a photo or pick one from your library, and tap the Korean text. SAM 3.1 finds the sign region, and Muse Spark 1.3 reads it together with the whole scene. It returns:
- what the sign says and how to read it
- why it is there
- what you should do now
- a bridge to your own language (e.g. 일방통행 = 一方通行 for Japanese speakers)

The answer is read aloud in Japanese, English or Chinese, and "Tell me more" adds web-grounded detail with sources. It runs in the phone browser with no install.
