RKKCS Revamps Service Introduction Page for Generative AI Manual System 'Otonarisan'

RKKCS Co., Ltd. (Headquarters: Kumamoto City, Kumamoto Prefecture; President and CEO: Atsushi Kaneko) has renewed the service introduction page for its generative AI manual system 'Otonarisan,' which began service in April 2025. The revamp was completed on June 15, 2026.

This is the first renewal since the service launch, featuring refreshed content such as feature highlights and frequently asked questions to deliver information more clearly.

Renewed Service Introduction Page

<Renewal Background>

Since launching the 'Generative AI Manual System Otonarisan,' RKKCS has expanded its adoption across local governments nationwide. Approximately one year after launch, increasing adoption has been accompanied by a rise in customer inquiries regarding functionality and implementation. This renewal revises the page structure and content to enable more intuitive understanding of 'Otonarisan’s' features, functions, and case studies based on these inquiries.

About the Generative AI Manual System 'Otonarisan'

'Otonarisan' is a generative AI system that ingests organizational documents—such as operational manuals, regulations, and FAQs—from local governments, financial institutions, and other organizations. Users can ask questions in natural language, and the AI interprets their intent and responds in clear, easy-to-understand language. The system can be adopted without specialized knowledge, with a fixed monthly fee, no data capacity limits, and support for direct upload of existing documents in formats such as Word, PDF, and Excel. Key features include: ① 'Question & Answer Function' where AI instantly responds to user queries, ② 'Keyword Search Function' enabling cross-document search by keyword, and ③ 'Text Summarization Function' that instantly summarizes long manuals.

<Features of Otonarisan>

1. Fixed Monthly Fee with No Data Capacity Limits

To support budget planning for local governments, we offer a fixed-rate pricing model. There are no limits on token usage or document storage capacity.

2. High-Precision Responses

Our proprietary tuning technology ensures high accuracy in responses. A list of source links is provided alongside each answer, allowing users to verify the validity of responses manually for peace of mind.

3. Easy Implementation

Users can begin using the system immediately after uploading documents, supporting diverse formats including txt, pdf, docx, xlsx, rtf, and md.

<Key Features>

▶ Like a veteran colleague next door: 'Question & Answer Function' for conversational queries

The 'Question & Answer Function,' with selectable language models, enables conversational-style questioning. It can be trained on municipal ordinances and unique operational manuals. An answer evaluation feature improves AI accuracy over time, delivering increasingly optimized responses with continued use.

▶ Pinpoint search for desired information: 'Keyword Search Function' that searches not just document titles but full content

Users can directly search for words within manuals and documents, extracting information from deep within files beyond the reach of standard file servers. Learning data and past query histories are also searchable, enabling more efficient information retrieval when combined with the 'Question & Answer Function.'

▶ Eliminates the need to read lengthy texts: 'Text Summarization Function' instantly captures key points

By copying, pasting, or uploading long documents such as meeting minutes or ordinances, AI instantly summarizes the key points concisely. This contributes to improved operational efficiency for busy municipal staff.

<Main Updates in the Renewal>

① Refreshed Features Page: Visually reorganized the three core features—fixed monthly fee, high-precision responses, and ease of implementation

② Enhanced Feature Explanations: Detailed descriptions of the Question & Answer, Keyword Search, and Text Summarization functions, accompanied by actual screen captures

③ Added Frequently Asked Questions: Organized pre-adoption inquiries in Q&A format to improve accessibility for potential users

④ Added Case Studies: Published real-world usage examples and user interviews from adopting municipalities
