note Launches "AI Context Network," a New Infrastructure Where Fan Voices Drive Sales

note will begin offering "AI Context Network," a new feature that connects reviews and feedback submitted to note to product purchases and content viewing, starting March 31.

The AI Context Network automatically collects and organizes official information about products and works published in the world using AI, and automatically generates respective pages on note. It aggregates related reviews and feedback posted on note, creating a mechanism that leads to actions such as purchase, reservation, and viewing.

For example, when you open a page for a certain novel, you can read official information and fan reviews in a list, and proceed directly to purchase. The collected word-of-mouth and official information will not only be read by people but also serve as a reference source for AI when generating responses. note aims to build an information hub for products and works that reaches both people and AI.

The system is designed to support products and works across all genres, including books, video content, music, cosmetics, games, and events. As the first phase, note has partnered with KADOKAWA Corporation to enrich official information for approximately 7,000 of their published titles. note is now widely recruiting partners from various industries.

Background: How expressing passion leads to creators' sales

As a vast number of new content and products are released daily, the burden of information dissemination on companies continues to increase. For example, a cosmetics manufacturer faces significant effort just to update information on its own website, social media, and various platforms, and to track fan reactions every time a new product is launched. Meanwhile, fans are constantly sharing their thoughts on social media and note.

If fans who want to support what they love and creators who want to reach interested people can connect, it should create a much greater force. The trend of making purchase decisions based on trustworthy words from others is growing stronger year by year. However, such word-of-mouth is scattered across various platforms and sites, making it difficult to find when needed. AI is beginning to solve this problem. Since AI cannot experience or have feelings itself, it generates responses by referring to primary information written by humans. The value of such primary information will continue to increase.

note has many primary information posts filled with love for favorite things. Furthermore, note articles are not consumed transiently; approximately 40% are still read a year later (*1). The "AI Context Network" is a mechanism that organizes corporate product and work information and creates pages where word-of-mouth is aggregated, thereby connecting fan voices to sales. Since the collected information is also referenced via AI, a virtuous cycle of increasing traffic over time is created.

What is the AI Context Network?

The name "AI Context Network" embodies two intentions: using AI to organize information, and the page itself becoming a hub for primary information referenced by AI.

On note, a large volume of word-of-mouth about products and works is posted. Review and feedback articles submitted to official note posting projects such as "#GoodThingsIBought," "#BookReview," "#MovieReview," "#GoodHotelsIStayedAt," and "#DeliciousRestaurants" have exceeded 1.26 million in total, with the number of posts in the past year growing approximately 3.1 times compared to three years ago (*2). While many review sites focus on star ratings and short comments within a few hundred characters, note features deep experiential articles spanning thousands of characters.

The AI Context Network aggregates such word-of-mouth for each product/work and connects it to purchases or views. For example, opening a page for a certain movie displays official information, allows direct ticket purchase, and lists fan reviews and feedback. For a new cosmetic product page, users can read reviews from creators who actually used it and then purchase it directly from an e-commerce site. This experience will be realized for all kinds of products and works. Official partner work pages can offer more enriched information and promotional measures.

Currently, in addition to approximately 7,000 KADOKAWA titles, the service widely supports popular books and video works available on Amazon. This feature is available on note's web browser and iOS/Android apps (please update the app to the latest version).

1. Automatic Information Collection and Database Creation

note's system regularly and automatically collects publicly available product and work information, and automatically generates respective pages on note. For official partners, more accurate and enriched pages can be developed based on their own website information. Pages and hashtags are automatically created in conjunction with new product launches or releases, ensuring no promotional timing is missed. Companies do not need to perform input or update tasks, reducing operational costs to near zero and allowing them to focus resources on their core business and marketing.

The following information will be displayed on the page:

・ Basic information (product name, price, release date, etc.)

・ Description

・ Images

・ Links to official websites and e-commerce sites

・ A list of related articles posted by creators (displayed by popularity/newest)

※AI-generated summaries of posted articles and links to related products, works, and people are also planned.

2. Aggregating Fan Feedback and Connecting to Purchases/Reservations

Articles such as feedback, reviews, and analyses posted by creators are automatically aggregated on the corresponding page. The enthusiasm of fans is visualized, allowing data-driven understanding of how many posts are gathered for which products or works.

Links to official websites and e-commerce sites like Amazon are placed on the work pages. This creates an environment where users can proceed to purchase, reserve, or view immediately after reading a review and finding it interesting. With detailed work information and fan voices aggregated in one place, it functions as a reference source for AI search and AI assistants, in addition to traditional search engines. Individual articles continue to be read over the long term, accumulating as promotional assets for companies.

Future Developments

We will build a new infrastructure where fan voices drive the economy, together with our partner companies.

・Expansion of Supported Genres and Partner Companies

Going forward, we will sequentially expand by partnering with various genres, including video content, music, cosmetics, and games.

・Report Provision and Sales Promotion Support

We will regularly provide partner companies with reports summarizing "what aspects are supported," "what improvements are expected," and "which demographics were impacted at what timing" for each product or work. Furthermore, we will support specific promotional measures such as proposing ways to generate buzz on note and distributing limited coupons. Since "real voices of consumers who have already experienced" are accumulated, deep consumer insights that are difficult to obtain through advertising measures can be grasped.

・"Feedback Request" Notifications Tailored to Interests

Based on past reading and writing trends, we will notify creators with matching interests, asking, "Would you like to write a review for this?" For RPG lovers, new RPGs; for mystery lovers, new novels; for beauty lovers, new cosmetics. This creates an environment where highly enthusiastic feedback is likely to gather before and after release.

・Creator Rewards and Opportunity Creation

We are considering a mechanism to reward creators for spreading works through their review articles. We also aim to create opportunities for enthusiastic creators to be recognized by partner companies, leading to collaborations and campaigns. We strive to build a cycle where expressing one's "love" also benefits the writer themselves.

※We welcome inquiries from companies and content holders interested in participating in this initiative.
