Problem

Kyoto Bank's internal chatbot depended on manually registered FAQs. Questions without entries still required human responses, while maintaining the FAQ collection added work.

Approach

The bank added PKSHA's generative AI document-search and answer-generation function to its existing chatbot in February 2025. It began operating against approximately 1,000 rules and manuals after several months of testing. The test reported 86% search accuracy.
