KB Kookmin Bank launches 'KB AI' service for financial searches and transfers

KB Kookmin Bank has unveiled a generative AI service that understands everyday language and guides customers from financial information searches through to account inquiries and transfers.

The bank said it has launched "KB AI," a generative AI-powered conversational financial service, within its KB Star Banking app.

KB AI analyzes the meaning and context of a customer's input, allowing users to find the services they need without knowing precise financial terminology or menu names. The service provides integrated natural-language search across menus, financial products and frequently asked questions within KB Star Banking.

The service goes beyond search to support actual financial transactions. If a customer types "Show me last month's debit card transactions," the system retrieves the relevant history; a request such as "Send my son 100,000 won ($73) for allowance" connects directly to the transfer service.

Customers do not need to navigate separate AI screens for different functions. Searches, inquiries and transfers are all accessible within a single chat window, reducing the steps users must take to find and move between features.

The bank also expanded multilingual support for foreign customers. Following the introduction of AI-powered translation for its KB Certificate issuance service in June, KB Kookmin Bank has now applied translation to the KB Star Banking membership registration process — covering everything from account opening to certificate issuance. The number of languages supported in the multilingual menu has also grown from 11 to 16.

The AI service operates within the bank's internal environment, isolated from external networks. The bank said it has applied encryption to the transmission of financial and personal data, maintaining the same level of security used for existing financial transactions.

"We hope this service makes it easier and more convenient for customers to access financial services," a KB Kookmin Bank official said. "We will continue integrating AI technology across a range of financial services to deliver new experiences for our customers."

Meanwhile, KB Kookmin Bank has been broadening its use of AI across operations. On Sept. 9, it deployed a self-developed "complaint counseling AI agent" in the field. On Sept. 3, it held the "2026 Group Integrated AI Agent Competition" to identify AI agents applicable to real-world business tasks — all part of the bank's push to use AI to deliver better financial experiences for customers.
