FullChinese is a GammaKite company started 12 years ago with the purpose of designing a learning ecosystem to allow learners of chinese to reach fluency level, in which they can read as they would with their native tongue. FullChinese was started by recognizing that language learning apps were designed for beginners but rarely for intermediate and more advanced learners. The goal of FullChinese was to go all the way. FullChinese serves as an academic learning tool (i.e., texts, quizzes and listening practice) and centralizes many language-learning features (i.e., personal dictionary, in-app translation, customizable sentences) into one app. Engineers and linguists have been working together to fulfill their vision of a language oriented app. FullChinese has been used in the past 6 years in major universities in the US.
