How to Ground a Korean AI Agent in Real Demographics with Synthetic Personas

# Plain-English Summary Researchers figured out how to make AI chatbots that understand Korean culture and demographics better by creating fake but realistic user profiles based on real data. Instead of training AI on generic information, they gave it synthetic personas—like "a 35-year-old Seoul resident who works in tech"—so it could learn how different groups of people actually think and communicate. This approach helps AI assistants give more relevant and culturally appropriate responses to Korean users.
