Hanja Annotation — Clarifying Sino-Korean Vocabulary
A large share of Korean nouns originate from Chinese characters (Hanja). Because many of these words share the same pronunciation but different meanings, formal writing and academic papers often annotate the Hanja in parentheses to remove ambiguity. This tool scans your input against a built-in dictionary of roughly 90 common Sino-Korean words and automatically appends the matching Hanja right after each word.

Everything runs locally in your browser, so nothing you type is sent to a server. Words missing from the built-in dictionary won't be annotated, so double-check the result before using it.
