Visualizing "Reasons to be Chosen" in an Era Where AI Proposes Products; ZETA's Review and Q&A Submissions Exceed 17 Million

ZETA Inc. (Headquarters: Setagaya-ku, Tokyo, hereinafter ZETA), which provides the CX improvement generative AI solution "ZETA CX Series" and supports the enhancement of customer experience value, announces that the total number of reviews and Q&A submissions on sites implementing its review, word-of-mouth, and Q&A engine "ZETA VOICE" has exceeded 17 million (as of the end of April 2026).

Background: The Growing Importance of UGC Data in the Era of Agentic Commerce

With the spread of generative AI and AI agents, "agentic commerce," where users explore, compare, and purchase products through dialogue with AI, is gaining attention. In this environment, it is crucial to utilize UGC (User Generated Content) such as actual purchasers' reviews and Q&A, not just product specifications and inventory information, to make proposals tailored to users' interests and usage scenarios.

ZETA is promoting initiatives for the era of agentic commerce through measures such as the "ZETA CX Series" compatibility with OpenAI "Apps in ChatGPT" (※1) and the expansion of multi-angle recommendations in the AI recommendation engine "ZETA RECOMMEND" (※2).

What becomes important in these initiatives is the enrichment of data that serves as the basis for product suggestions. Especially when proposing products on conversational UIs like ChatGPT or on digital shelves, utilizing reviews and Q&A makes it possible to present not only "what to recommend" but also "why to recommend it" to users.

UGC is expected to further increase its value as a data asset that provides conviction and trustworthiness to AI-driven product suggestions.

Achievements: Review and Q&A Submissions Exceed 17 Million

The number of reviews and Q&A submissions in "ZETA VOICE," which is being implemented mainly by major domestic EC sites, has steadily increased since surpassing 16 million in February 2026, and has now exceeded a cumulative total of 17 million. (※3)

The background to the expansion of review and Q&A submissions includes an increase in opportunities for users to share their pre- and post-purchase experiences and questions, as well as the growing importance of "voices of actual users" in purchasing decisions on EC sites. Furthermore, reviews and Q&A are not limited to being information referenced on product detail pages, but are also increasingly being utilized as data to improve the accuracy and conviction of generative AI-driven product suggestions, searches, and recommendations.

ZETA is promoting the utilization of UGC data accumulated by "ZETA VOICE" as a data asset that contributes to the advancement of the entire "ZETA CX Series." In particular, the "multi-angle recommendation" in the AI recommendation engine "ZETA RECOMMEND" supports product display utilizing reviews and Q&A, in addition to multiple angles such as popular products, trends, hashtags, and personalization.

This enables users to compare and consider products while referring to the voices of actual purchasers, leading to a more convincing purchasing experience.

Outlook: Advancing CX in the Era of Agentic Commerce Driven by UGC

In an era where AI is involved in product discovery and purchasing decisions, possessing and utilizing vast amounts of UGC data becomes a crucial factor supporting the competitiveness of EC operators.

ZETA will seamlessly realize a series of purchasing experiences for users – "finding," "comparing," and "confidently choosing" products – by leveraging over 17 million review and Q&A data accumulated in "ZETA VOICE" across various touchpoints such as comparison on digital shelves and compatibility with ChatGPT apps.

Especially when generative AI and AI agents propose products, UGC data based on the voices of actual users plays an important role in providing trustworthiness to AI's answers and suggestions. ZETA will continue to utilize the rich UGC data in "ZETA VOICE" to support the improvement of CX required in the era of agentic commerce.

ZETA will continue to provide beneficial services to users and EC site operating companies, leveraging its strength in AI-driven data analysis.
