Liulishuo

The company's core offering is its mobile app, "英语流利说" (English Liulishuo), which functions as an "AI English Teacher." This platform utilizes deep learning and adaptive learning technologies to provide personalized lesson plans for users. A key asset is the company’s proprietary database, considered the world's largest collection of Chinese speakers' English speech, which powers its speech recognition and multi-dimensional scoring engine. The platform provides users with instant, granular feedback on pronunciation and fluency, covering listening, speaking, reading, and writing. To enhance user engagement, the app incorporates gamified features and social elements, fostering an active learning community. Liulishuo operates on a "freemium" business model, attracting a large user base with free content and then converting them to paid subscribers for access to premium, personalized courses. Its product suite has expanded to include specialized apps like "LiuLi Reading," "Kids Liulishuo" for children, and "IELTS Liulishuo" for test preparation, as well as providing learning services to corporate clients.

A significant milestone for the company was its initial public offering (IPO) on the New York Stock Exchange (NYSE) on September 27, 2018, under the ticker symbol "LAIX," raising approximately $71.9 million. This move was intended to fund further research and development and expand marketing efforts. However, the company faced challenges in maintaining its stock performance. In April 2022, the NYSE initiated delisting proceedings for LAIX after its market capitalization fell below the required standard.
