Problem

Customers needed a convenient way to check account information and pay credit-card bills through text messages. Their wording varied widely.

Approach

Capital One introduced Eno in an invitation-only pilot in March 2017. It used supervised machine learning to understand customer requests and refined the assistant from conversations. In October, Capital One made Eno available to millions of customers.

Results

Takeaway

Pilot conversations helped the bank train Eno on different ways customers asked routine questions. The bank reported participation without quantifying service-cost savings.
