Integration of communication windows into AI agents
To upgrade CX, LY will unify all communications with users, which was previously separated by channels, into one, into the LINE Official Account. This will allow users to first consult with an agent on LINE when inquiring about each brand or service.
Shohei Niki, LY Senior Product Manager, said that LY is creating a brand agent experience that users will recognize.
For the next generation marketing, LY will implement an AI agents into the LY service management screen. It will autonomously take action based on marketers' needs and provide end-to-end support for marketing from upstream to downstream.The agent begins talking with customers, and then real-time interactions begin. To support it, communication functions such as voice input and video input will be available.
To help partners exploit insights, LY will deepen understanding of user insights and even propose next steps through combination of search data, information delivery results, first-party data and so forth.
Furthermore, campaign design will be automated for the optimal communication plan based on budget and objectives, and proposes creative and targeting settings to match the plan autonomously. Niki said, “We aim to create experiences for partners to operate their businesses directly and intuitively.
