Japan's LINE Yahoo Launches Standalone iOS App for AI Agent 'Agent i' with Price-Drop Alerts
LINE Yahoo releases standalone iOS app for Agent i, adding price-drop alerts and expanding domain-specific agents.
Japanese internet giant LINE Yahoo Corporation launched a standalone iOS application for its AI agent "Agent i" on November 10, 2026. Previously accessible only within the LINE or Yahoo! JAPAN main apps, the service can now be launched with one tap from the home screen. An Android version is expected to roll out subsequently.
Agent i was introduced in April 2026 by integrating Yahoo! JAPAN's "AI Assistant" and LINE's "LINE AI." The new standalone app features a "Task Function" that allows users to register keywords for continuous monitoring of latest news, product price drops, or event schedules, sending app notifications when tasks are completed. It also supports quick access to new chats, image input, and voice input via home screen widgets.
The number of "Domain Agents" has expanded to a cumulative 40 (including beta versions), featuring an "Oshikatsu" (fan support) agent launched on September 24. This agent organizes the latest information, events, tickets, and merchandise for users' favorite artists or characters.
Users can log in with a LINE account or Yahoo! JAPAN ID; some functions are available without login, though free-form text input requires authentication. According to reports, Agent i utilizes the Gemini Enterprise Agent Platform (formerly Vertex AI) or OpenAI APIs under the hood. The app is rated 13+ on the App Store, with guidelines advising against use by children under 13.
