Stock Inc. (Headquarters: Chuo-ku, Tokyo; President and CEO: Daisuke Sawamura; hereinafter "the Company") announces the official launch of its AI knowledge tool, "Narekan," on July 9, 2026.

Since its alpha launch in 2024, "Narekan" has been continuously refined through extensive dialogue with numerous "non-IT companies" and a commitment to a ground-up approach. We are now officially launching "Narekan" as it offers a comprehensive suite of features that support the entire lifecycle of knowledge, from consolidation and search to updating and utilization.

With this launch, we are repositioning "Narekan" as a product that "cultivates knowledge and unlocks corporate potential," supporting the sustainable growth of "non-IT companies."

AI Knowledge Tool "Narekan" for "Non-IT Companies"

"Narekan" is an AI knowledge tool designed for "non-IT companies."

It enables "non-IT companies" to centralize knowledge without confusion and make it readily usable through AI and keyword search. By combining this with a system that encourages natural participation from internal members, ensuring information is always accurate and up-to-date, we create an environment where knowledge continuously grows.

Furthermore, we provide robust support to ensure these systems become ingrained in the organization and lead to sustainable corporate growth.

"Narekan" has been adopted by many companies, including Shiseido Co., Ltd., Furukawa Electric Co., Ltd., and Kubara Honke Group, and is trusted as a partner supporting organizational knowledge utilization.

Background of Official Launch: Towards a Partner in Cultivating Corporate Knowledge

At the time of its development, "Narekan" was positioned with "a system for consolidating information" and "natural language search powered by AI" as its core strengths.

The experience of searching vast amounts of accumulated internal information using natural language has been highly praised by many users. However, through numerous conversations with users from "non-IT companies," we concluded that simply being able to "find information" is insufficient for successful knowledge management.

For companies to grow sustainably, they need a system that not only accumulates knowledge but also continuously cultivates it. Insights generated at the ground level should naturally spread throughout the organization and be stored as corporate knowledge. Furthermore, this knowledge must be continuously updated and nurtured. This cycle is the essence of knowledge management.

Therefore, "Narekan" aims to be a presence that maximizes the inherent potential of companies while supporting their knowledge management through five key features.

Comment from President and CEO Daisuke Sawamura

Our mission is to "remove the stress of information sharing from non-IT companies worldwide." Guided by this mission, we have consistently engaged deeply with people in "non-IT companies."
