Understanding RAG and AI Agents: A Comprehensive Guide by Tsutomu Kai

Introducing a New Perspective on RAG and AI Agents



On August 25, 2026, Tsutomu Kai, the CEO of SniffOut, will unveil his debut publication titled "Understanding RAG and AI Agents: A Comprehensive Guide." This insightful book aims to bridge the gap between learning concepts and practical application in the evolving field of AI. Available in bookstores across Japan and online platforms such as Amazon and Rakuten Books, this book is poised to be an essential resource for businesses looking to harness the power of AI technology.

The Need for Practical Knowledge



As companies explore the potentials of Retrieval-Augmented Generation (RAG) and AI agents, they encounter numerous challenges beyond theoretical understanding. Many fail to integrate these technologies successfully into their operations, despite promising Proof-of-Concept practices showing initial success. The disconnection between theoretical excellence and practical deployment often leads to disillusioned teams and unrealized goals.

In his book, Tsutomu combines his extensive experience, having supported over 200 companies in AI implementation and design, to elucidate RAG's accuracy and the strategies necessary to embed AI agents within organizational structures.
