SoftBank’s venture capital arm and GSR Ventures led a $20 million Series B funding round in XueXiBao (‘study treasure’), a Chinese startup that has created an app to help junior high and high school students with their maths, science and English homework.

Students can upload content like text, maths problems and diagrams to the app which uses image and optical-character recognition to understand the data and provide answers and other relevant information.

According to XueXiBao, the app processes content in six seconds and is 85 to 95 per cent accurate. Students can also ask teachers questions by uploading a voice clip for a fee.

As students in China look for innovative ways to prepare for university entrance exams, online platforms like massive online open courses (MOOC) and TutorGroup, backed by SoftBank and Alibaba, are becoming increasingly popular.

However, XueXiBao is different in that it caters to a younger audience.

SoftBank has been investing in a number of mobile app companies recently. Just last week, it put $600 million into taxi app Kuaidi Dache.

SoftBank head Masayoshi Son has previously said the company will not slow down investments in Asia’s “massive wave of internet revolution”.
