LINE Yahoo will launch a standalone AI agent app in October.
The service now has 27 domain agents and 12 million daily users.
It targets Japan-specific tasks to compete with global AI firms.
What happened
LINE Yahoo announced it will launch a standalone app for its AI agent service "Agent i" in October, available on iOS and Android. This expands access beyond the current LINE tab and Yahoo! JAPAN icon.
Why it matters
Since the service began in April, the number of domain agents has grown from 7 to 27, and daily active users reached 12 million. The company plans to expand to 40 domains by October, positioning itself against global players like OpenAI and Google in the AI agent market.
What to watch
The company has pre-released prototypes for 8 new agents, including calendar, pet life, and short video creation. It also aims to scale its domain agents to tens of thousands, leveraging its unique data to reduce AI hallucinations.

LINE Yahoo's move to a standalone app comes as AI agents move from simple Q&A to executing tasks. The company emphasizes its "moving AI" concept, where agents perform actions rather than just answering. This shift is supported by a new internal development approach: about 20 working groups now use AI to create prototypes and iterate rapidly. The CPO says trial-and-error speed has multiplied tens to hundreds of times, cutting development from three months to much less. The company's competitive edge lies in its 30 years of accumulated data, used to embed accurate, domain-specific information into agents to prevent hallucinations. With a focus on Japan-specific domains, LINE Yahoo aims to differentiate from global rivals by dominating local daily tasks. The success of the standalone app will test whether it can attract users beyond its existing LINE and Yahoo! JAPAN base.
