WorkingCompany's own claimOfficial ↗

Problem

Staff needed to summarise documents and find information about prefectural administration.

Approach

Osaka ran a generative AI trial from November 2023 through January 2024. It introduced a dedicated staff system in December 2024 through its internal chat tool. Functions included answering from internal information and summarising attached documents.

Results

about 88.8%trial survey respondents who considered generative AI useful for their work, according to OsakaCompany's own claim[1]
about 93.1%trial survey respondents who wanted to continue using it, according to OsakaCompany's own claim[1]

Takeaway

The reported percentages measured staff opinions during the trial. They did not quantify time saved after full deployment.
