KakaoBank

Conversational AI assistant in the banking app

KakaoBank said its conversational AI service passed 5 million users in about a year

WorkingCompany's own claim

Problem

Customers needed help finding banking functions and understanding financial information. KakaoBank sought to make those services accessible through conversation.

Approach

KakaoBank launched AI Search in May 2025, then combined financial calculations and transfers with information retrieval in KakaoBank AI. An April 2026 update added investment-information and card-benefit searches.

Results

more than 5 millionservice users in about a year after launch, reported by KakaoBankCompany's own claim[1]

90%+answer satisfaction after improvements, reported by KakaoBankCompany's own claim[1]

Takeaway

The user count measured service reach. It did not establish a reduction in customer-service costs.
