Az Marketing Inc. (CEO: Masato Kikuchi, Koshigaya City, Saitama) announced the official release today, April 1, 2026, of its SaaS product "AIMention (AI Mention)," which automatically measures and visualizes the citation status of websites by AIs such as ChatGPT, Perplexity, and Gemini.

Background of the Release
With the rapid spread of information gathering using generative AI such as ChatGPT and Perplexity, we have entered an era where whether "your company's site is cited by AI" impacts customer acquisition and branding, similar to search engines like Google.
This new metric is called "AEO (Answer Engine Optimization)" and "LLMO (Large Language Model Optimization)" and is attracting attention from marketers both domestically and internationally. However, tools that can continuously measure and manage AI citation status are often high-priced services, making them difficult for small and medium-sized enterprises (SMEs) and sole proprietors with limited budgets to adopt.
Investigating AI citation status alone incurs significant costs, leading to many cases where personnel manually check or give up on countermeasures.
AIMention was developed to solve this problem. By simply registering keywords, it automatically measures and visualizes citation status across three AI models, making it a service that allows anyone to easily measure the effects of AEO/LLMO countermeasures.
