QANDA is an AI-based learning platform developed by Mathpresso Inc., a South Korea-based education technology company. It uses optical character recognition technology to scan problems. Students can take a photo of a problem and receive step-by-step solutions within five seconds. QANDA supports all subjects including math, science, English, and social studies. [1]

History

CEO Jongheun ‘Ray’ Lee first came up with the idea of QANDA during his freshman year in college. While he was tutoring to earn money, Lee realized that the quality of education a student receives is greatly based on their location. Lee saw his K-12 students were regularly asking similar questions and realized that these questions are from a pre-selected number of textbooks currently being used in schools. He decided to team up with his high school friend, Yongjae ‘Jake’ Lee to build a platform where by way of using a mobile app to scan and submit questions, students can ask and receive detailed responses.[2][3]

In June 2015, Mathpresso, Inc. was founded in Seoul, South Korea.[4] Since its inception, it got its backing in Series B funding from investors namely Legend Capital, InterVest, NP Investments and Mirae Asset Venture Investment.[5]

In January 2016, Mathpresso's first product QANDA was launched. It supported a Q&A feature between students and tutors.[6]

In October 2017, QANDA introduced an AI-based search capability that permitted users to search for answers in seconds. [6]

As of 2021, QANDA is used in over 50 countries and has achieved a no.1 on the education chart in 6 countries, surpassing similar apps. [7]

Features
