The 20 Chinese-language episodes of the online TOPIK (Test of Proficiency in Korean) preparation course from 365ENM, a Korean education company, were produced by AIPARK with AiVATAR in 2023. The same course was supplied as 20 episodes each in Chinese, Vietnamese and Mongolian — 60 videos in total — using the same AI instructor throughout, with only the audio changed per language. 365ENM adopted the approach to cut the cost of filming instructor-led lessons. It is an example of extending one course build into three languages of Korean-language education content.
