■ Background of Implementation
Attenir offers cosmetics, supplements, and fashion items for adult women. The "Attenir Official Online Shop" has provided various channels such as phone, email, web chat, and FAQ, promoting the establishment of an easy-to-use support system for customers. Mobilus has supported this by facilitating rapid FAQ updates for Attenir's chatbot, thereby promoting customer self-resolution.
Conventional chatbots were keyword-matching, which posed a challenge as they could not provide appropriate answers when customers asked questions in free-form text or used words/synonyms not found in the FAQ, leading to cases where self-resolution was not achieved. As a result, inquiries were directed to phone calls or human chat, leading to an increased burden on operators. Furthermore, with rising labor costs and labor shortages, there were limits to strengthening support by increasing the number of operators, necessitating the introduction of a new system.
Against this background, Attenir was considering introducing a highly accurate chatbot capable of providing answers to promote customer self-resolution and improve response quality and operational efficiency. Among the candidates, Mobilus's "MOBI BOT AI Vector Search," which can handle ambiguous expressions, was selected.
In the proof-of-concept (PoC) conducted in December 2025 at FANCL Corporation, a group company, the inquiry completion rate improved by approximately 20% in the chat support of the "FANCL Online" FAQ site and the LINE official account "FANCL Customer Support." This promoted customer self-resolution and confirmed operational efficiency improvements such as reducing human intervention. Following its implementation at FANCL, it was subsequently adopted by Attenir.

■ Overview of Implementation
"MOBI BOT AI Vector Search" is characterized by its ability to handle synonyms and variations in notation through vector search, and to accurately search and present semantically similar FAQs even for natural language questions entered freely. This allows the AI to understand the context and provide optimal answers even for ambiguous expressions, words not matching FAQs, or long questions that were difficult for conventional chatbots to handle. Furthermore, since the answers are based on registered FAQs, it prevents misresponses (hallucinations) unique to generative AI, enabling highly reliable information provision.
