Longyan

Read Chinese anywhere. Understand what it actually means.

Longyan (龙眼) is a passive Chinese reading assistant for learners who want to understand what a text actually means, not just what a dictionary says. How it works: Highlight any Chinese text on any webpage. Longyan instantly surfaces: Word-by-word pinyin with per-syllable tone coloring Contextual English translations Semantic gap explanations- flagging when the English loses cultural weight, register, or implied meaning that exists in the Chinese Why it's different: Most translation tools give you the 80% match. Longyan exists for the other 20%: the cultural context, the weight of a word, the nuance that doesn't survive a dictionary lookup.
