Problem

Sankyo Tateyama decided in June 2023 to use generative AI actively. It needed an internal assistant that could create minutes and answer questions from company documents.

Approach

The company built version 2 of its assistant, AI Futaba, in about one month on the open-source AWS project GenU. It uses Amazon Bedrock, Amazon Kendra for retrieval over internal documents, and some external models. It offers minutes creation with transcription and about 50 prompt templates for common business tasks. AWS Japan co-wrote the blog post.

Takeaway

Inconsistent product names in internal documents needed extra handling, such as metadata, before document search gave usable answers. The 15,000 annual hours saved are a projection, not a measured result.
