German artificial intelligence translation startup DeepL on Wednesday launched traditional Chinese as a language option as it looks to expand its presence in Asia. DeepL, one of Europe's high-profile AI companies valued at $2 billion, sells translation software aimed at businesses rather than everyday consumers. Traditional Chinese is a written form of Chinese used in Taiwan and Hong Kong. Both locations are key business hubs for technology and finance — a factor that attracted DeepL to launch its latest language in those markets.
