WorkingVendor case studyVendor ↗

Problem

Toyota Finance sends campaign emails and app push notifications to credit card members. Each message had to be checked against Japanese advertising regulations, and the checks took staff time.

Approach

Toyota Finance worked with IBM Client Engineering over about 10 months in an IBM Cloud sandbox. The team built a tool on IBM watsonx.ai and Red Hat OpenShift that proofreads text and checks it for compliance. The tool has been in use since November 2024. A second tool for drafting dealership FAQs was still in a verification phase.

Results

10%reduction in check time for text emails and app push notifications, with better accuracy and quality, per IBMVendor case study[1]

Takeaway

The first tool to reach production was a narrow back-office check. The FAQ tool for dealerships was still being tested.
