What can Murata Coworker actually do?

Beyond general writing, summarizing, idea generation and research, it offers Murata-specific functions: "PPT Add-on" for presentation creation, "Translator" for translation, a "RAG system" link for internal data, "Researcher" for investigations, and "Help Desk" for IT service management. Senior manager Kenta Suzuki said that after its release, the number of people making their own PowerPoint presentations internally dropped sharply.

How is Murata handling the risks of AI agents?

Murata says it drafted AI agent governance guidelines jointly with AWS, covering risks specific to agents such as input, the reasoning process, memory, multi-agent setups, and use of external tools and data. It also sets risk-level criteria and a policy for human-in-the-loop intervention, and uses Amazon Verified Permissions for fine-grained authorization combining RBAC and ABAC.

Murata's in-house AI "Murata Coworker" hits 30,000 users

Send on LINE

3 Key Points

What happened
Murata Manufacturing's in-house generative AI "Murata Coworker" has reached about 30,000 cumulative users and about 20,000 monthly active users, with usage rate rising from 16% in July 2024 to 52% in July 2025.
Why it matters
The tool is credited with cutting about three work-hours per person per month and driving efficiency savings in the range of several billion yen annually, moving AI from a pilot into everyday company operations.
What to watch
Murata says it will next build an AI agent platform and expand into Physical AI and digital twins; the test is whether its jointly developed agent governance guidelines keep pace with agents that autonomously access tools and data.

WHO IT HITSCorporate IT and DX teams at large manufacturers rolling out internal generative AI now have a worked example: a homegrown assistant reaching roughly 30,000 users with published adoption and time-savings figures. Companies weighing agentic AI will also watch Murata's governance and authorization designs, which it says it developed with AWS.
