Sumitomo Mitsui Card

AI drafts for contact-centre email and chat replies

WorkingCompany's own claim

Problem

Contact-centre operators needed to prepare answers using internal information. Early AI drafts were often judged unhelpful.

Approach

Sumitomo Mitsui Card worked with ELYZA on a system that retrieved internal information to generate reply drafts. Email use began in late June 2024, followed by chat in December. The company collected problems identified by operators and improved the retrieval data.

Results

85%drafts judged useful in March 2025, up from 46% in July 2024, according to the companyCompany's own claim[1]

Takeaway

The usefulness measure reflected operator judgments about drafts. It did not measure independently verified answer accuracy.
