Jenny Sun LLC (Tokyo, Representative: Daichi Hokuetsu) has officially released a specialized consulting service for 'AIO (AI Optimization)'—designed to ensure corporate information is cited and recommended by AI search engines like ChatGPT, Perplexity, and Google Gemini—along with Japan's first free AIO score diagnostic tool, 'AIO Free Diagnosis' (https://scan.jennysun.jp).
## Background
Since 2024, the number of users who 'ask ChatGPT first' has surged, leading to a decrease in Google search clicks. Meanwhile, inquiries via AI search are often reported to have higher intent and significantly higher conversion rates compared to those from traditional SEO.
However, as of 2026, it is estimated that less than 1% of Japanese companies are implementing AIO. Many SMEs continue to lose acquisition opportunities without realizing the necessity of 'optimization for AI search.' To address this, Jenny Sun LLC was established in 2025 as a company specializing in AIO.
