LY Corporation has unveiled the blueprint for its company-wide AI transformation (AX) strategy, spearheaded by generative artificial intelligence. Over the past year, AI has written 20% of development code, and the company also showcased an internal tool that allows non-engineers to build AI agents in just one day.
LY announced on the 6th that it held its technology conference “Tech-Verse 2026” on the 29th of last month, conducting a total of 15 sessions centered on AI and core technologies.
The keynote addresses were delivered by Park Ui-bin, LY’s Chief Technology Officer (CTO), and Namiki Ryota, LY CTO and head of the Domain AI CBU & AI Strategy Planning Group. They spotlighted the advancement plans for the generative AI agent “Agent i” and the current status of the AX initiative aimed at transforming the entire organization into an AI-centric entity.
Agent i is a generative AI agent service launched by LY in April. It currently assists users with their daily lives across a cumulative 22 domains, including shopping, going out, and food recipes. LY plans to evolve the service by organically linking multiple AI agents to more accurately grasp user intent and proactively suggest necessary information before users even search for it.
The technical foundation for this was also revealed. LY has internally developed an “Agent Builder” that allows even non-AI engineers to create AI agents within a single day. Furthermore, the company has built a solution that connects AI agents to internal data and application programming interfaces (APIs), while tracking and managing the connection status of each agent in real time. This approach simultaneously secures development speed, safety, and governance, the company explained.
Personalization features will also be significantly strengthened. LY introduced concepts for a “long-term memory” feature that selectively stores conversation histories with users for extended periods, and a “memory integration” feature that links Agent i conversations with Line and Yahoo Japan service usage data in real time. These are key mechanisms designed to provide optimal responses tailored to a user’s situation without requiring separate prompt input.
As AI agent competition shifts beyond simple chatbots to how naturally they can connect real actions such as search, shopping, reservations, and payments, LY’s position—holding both the Line messenger and Yahoo Japan services—draws attention. However, how to link data between services while ensuring personal information protection and internal controls is expected to be a core challenge for the AX strategy.
LY is also accelerating the AI transformation of its own organization. The company stated it has established a five-stage roadmap to convert over 100 services, some operating for more than 30 years, into AI-centric platforms, and is gradually reorganizing internal systems, data, and workforce capabilities.
Notably, in the development process, the focus is on actively introducing AI from the planning and design stages, rather than merely using it as a coding assistance tool. To this end, the company has concurrently worked on structuring internal documents into formats easily understood by AI and visualizing relationship maps between services.
As a result of these company-wide efforts, LY explained that AI-written code accounted for 20% of the total over the past year. This is a noteworthy achievement considering the large-scale systems that have been in operation for an extended period.
This year, LY plans to push forward with AX at the organizational and service levels with greater speed, moving beyond individual productivity improvements. The company stated, “In line with our ‘WOW OUR Users!’ mission of delivering experiences beyond imagination, we will continue to accelerate service development and talent cultivation in the AI domain, further speeding up our AX initiatives.”
