A commentary by the writer 针尖, carried by Huxiu AI and republished by Tmtpost, describes Chinese and Korean education entrepreneurs packaging East Asian exam-training methods into AI apps sold overseas. It reports that Korean adult-education product Speaker launched in the second half of 2024, raised $78 million from Accel and within about a year ranked first in Korea's online English education market; that ByteDance's Gauth had over 200 million global installs and 53.41 million monthly active users as of September 2026 (the same article elsewhere says 300 million users); that Zuoyebang's Question.AI stayed in the top five of the North American iOS education chart; and that Yuanfudao's Uknow.AI ranked first in user activity among similar apps in Vietnam. It also covers Korea's QANDA, Socra AI's Santa with an ETS content-licensing deal, Japan's Qubena selling through public-school procurement and AvoLingo's B2B engine, distilling three paths: tools first, exam culture as a moat, and B2G/B2B differentiation.
