Washin Co., Ltd. releases AI marketing book free in four languages for commercial use

TOKYO, November 1, 2026 - Washin Co., Ltd. (IDAEO) today announced that it has released TK Lin's book "IDAEO: Market Strategy for the AI Era" free of charge in Traditional Chinese, Simplified Chinese, English and Japanese under the CC BY 4.0 license, which allows commercial use. The free release began on October 26, 2026. The book, written by TK Lin, has nine chapters and 36 figures and is available as a web edition, PDF, mobile PDF (A5) and EPUB. Its conclusions are checked against 105.5 million cumulative requests to the author’s websites recorded by Cloudflare by October 8, 2026. It affects small businesses, marketers, teachers and researchers, who can now use the full book at no cost. It matters because customers increasingly ask AI before choosing a business, and whether AI reads, names and describes a business correctly is a different matter from keeping a search ranking.

Readers can now read the web edition or download PDF, mobile PDF and EPUB versions at no charge. With credit to the source, they can share the book, teach from it, adapt it and use it commercially without requesting permission. That permission does not expire. Readers who want to be notified of new editions can register their use for free by December 31, 2026; registration is optional.

Cloudflare recorded 105.5 million cumulative requests to the author’s websites by October 8, 2026. The total includes requests from AI, search engines and automated bots. It does not mean AI used the content. The Cloudflare dashboard is not public, so outsiders cannot verify the count directly. The book says the figures cannot be compared directly with traffic to a single merchant’s website and identifies the source, scope and unit of its measurements.

The book draws on TK Lin’s tests of AEO, GEO, SEO, LLMO and AIO knowledge and literature on the author’s own website. It offers reading paths for shop owners, marketers, researchers and people without a marketing or website background. It asks readers to examine whether AI reads, names and describes a business correctly, then check the results against data. No secret method guarantees a ranking.

In the preface, TK Lin describes Washin Cat Village as “trying to use AI to make itself known around the world” and says the book shares hands-on experience with small and medium-sized businesses. The preface credits businesses in Taiwan and Japan that used TK Lin’s AEO checker as a reason for putting the lessons into a book.
