About
Our books are drafted with BookOrchestra, a multi-agent writing system that splits planning, research, writing, editing and fact-checking into separate roles. The AI that writes a draft never approves it; the final call is always human.
The press is run by Kwangwoo Song, who spent about 30 years in B2B consulting before retiring in 2026. He grew up in Seoul and speaks Korean as his native language. In Korea the press also publishes Korean-language books on AI, careers and travel.
