Korail has blocked the AI agent Pickle, which plans and carries out tasks on its own. Pickle can no longer book or operate train tickets through Korail.
Key points
Korail recently began blocking automated programs, including macros (programs that repeat tasks automatically) and AI agents like Pickle.
Korail says the aim is a fair and stable ticket booking environment.
United Airlines in the United States also said it will stop AI agents from booking flights on its website and app.
Naver is considering allowing AI agent access only for its partner companies.
Why it matters
As AI tools increasingly buy goods and book tickets for users, companies are deciding whether to let outside AI in or keep it out.
