LINE Yahoo has released its AI agent Agent i as a standalone app. It is available on iOS first, and an Android version is planned to follow in stages.

Agent i is not entirely new. Users of LINE may know it as the purple gradient icon at the top of the app. The service has been available since April 2026, when it merged Yahoo! JAPAN's AI Assistant with LINE's LINE AI. The new release gives it a dedicated app of its own.

What the app does

Users can sign in with either a LINE account or a Yahoo! JAPAN ID, though some features work without logging in. As an agent, it notifies users about the latest news on keywords they register, price drops on products and upcoming events.

Purpose-specific "domain agents" now cover a cumulative total of 40 areas, including beta versions. In September, an "oshi-katsu" agent was added for fans: it organizes the latest news, ticket information and merchandise details about the artists or characters they follow.

Being a full app also means it can run as a home-screen widget, which is a practical advantage over using it only inside LINE.

Why it matters

Agent i is built around everyday Japanese services, which sets it apart from general-purpose assistants such as ChatGPT and Gemini. For the large base of LINE and Yahoo! JAPAN users, a standalone app puts that local focus one tap away rather than tucked inside a messaging app.

No date has been given for the Android release beyond the company's statement that it will arrive progressively.
