AI Assistant in a Bank’s Customer Service Department: Responses with Source Citations

Background

In a bank’s advisory and customer service departments, every response was crafted manually. Employees searched internal documents, FAQ collections, and Microsoft 365, and then formulated the responses themselves. This took time. The responses were inconsistent, and the business units and the audit department were often unable to trace the sources.

Solution

Today, an AI assistant generates a draft response based on the bank’s public website content and links each statement to its source. It is integrated directly into the user interface and logs every step. Employees review the draft, make adjustments, and approve it. Since the system went live in August 2026, the time spent searching per inquiry has decreased by 30 to 50 percent, and the turnaround time until a draft is ready has decreased by 20 to 40 percent. Two additional units are currently adopting the modules.

Guten Tag, ich habe gestern Abend meine Debitkarte verloren. Was muss ich jetzt tun, und wie schnell bekomme ich eine neue Karte? Ich bin nächste Woche im Ausland unterwegs. Vielen Dank, M. Berger

Guten Tag Herr Berger, bitte sperren Sie die Karte sofort in der Banking-App unter „Karten › Sperren“ oder über die Sperrhotline. Die Ersatzkarte beantragen wir gleich für Sie; sie wird in der Regel innerhalb weniger Werktage zugestellt. Für Ihren Auslandsaufenthalt …
