Kirayaka Bank Introduces "Helpfeel" as Internal Information Search Platform, Enabling Instant AI Search and Retrieval of 10,000 Pages of Regulations and Notices

Helpfeel Inc. (Headquarters: Kyoto City, Kyoto Prefecture, CEO: Isshu Rakusai, hereinafter "Helpfeel"), which accelerates the social implementation of AI through the power of knowledge, is pleased to announce that Kirayaka Bank (Head Office: Yamagata City, Yamagata Prefecture, President: Hideki Nishizuka, hereinafter "Kirayaka Bank") has introduced "Helpfeel" as its internal AI knowledge search system.

This implementation has created an environment where approximately 10,000 pages of PDF documents, including internal regulations, operational details, and notices, can be searched collectively. By reducing the document search time, which previously took 90% of employees over 5 minutes, and building a search platform that allows for quick access to necessary information, we aim to support operational efficiency and productivity improvement.

Kirayaka Bank Introduces "Helpfeel" as Internal Information Search Platform

Background of Implementation: Information Dispersion Hinders Self-Resolution, Leading to Constant Inquiries to Headquarters

Kirayaka Bank is currently undertaking "Organizational Culture Reform 100" as a bank-wide initiative. During this initiative, it was identified that inquiry operations between sales branches and headquarters were becoming a burden.

Inquiry operations involve receiving requests for information via phone from bank employees and providing the necessary information requested by those employees. Due to the dispersed nature of information such as internal regulations, notices, and manuals, and the difficulty in finding necessary information with the conventional document management system, phone inquiries to headquarters were frequent, especially from younger employees or those who had recently transferred. As a result, the workload for both sales branches and headquarters increased, leading to delays in customer service, heightened operational risks, and increased psychological burden on employees.

Reality on the Ground: 90% Spend Over 5 Minutes Searching. Time and Psychological Costs Become Apparent

Prior to the implementation of Helpfeel, a survey on operational realities conducted among all employees (conducted in January 2026 / 234 responses) revealed the actual situation.

Extended Search Times: 90% of employees reported taking "over 5 minutes" for a single information search. Furthermore, over 30% of employees responded that they took "over 10 minutes" or "gave up without finding it."

Manifestation of Psychological Burden: Numerous comments were received, such as "I feel bad about taking up others' time by asking headquarters or colleagues," "I'm anxious about the recency of information," and "I feel stressed, constantly fearing operational errors."

Expectations for Problem Resolution: 98.7% of employees responded, "I definitely want to use Helpfeel, I want to use it if it will be convenient."

These results indicate that a new information platform capable of comprehensively searching and utilizing internal information is needed, not only for improving operational efficiency but also from the perspective of supporting psychological safety.

This Initiative: Enabling AI Search of 10,000 Pages of Regulations and Notices

To address these challenges, Kirayaka Bank has introduced "Helpfeel (Intent Prediction Search 3)" as its internal AI knowledge search system. "Intent Prediction Search 3" is an AI knowledge search mechanism that utilizes generative AI (LLM) and RAG (Retrieval-Augmented Generation) technology to search across PDF documents such as regulations, notices, and manuals. In addition to AI-generated answers, the search results also present the relevant sections within the source PDF documents, allowing users to quickly access the information they need while confirming its accuracy.

<Key Features>

Searchable with "Conversational Language" It supports conversational language such as "How do I write the terms and conditions?" or "What should I do if something is lost?", as well as specific financial industry phrasing. It predicts the user's intent while searching through vast document collections and instantly displays the answer.

Cross-Search of 10,000 Pages of PDFs It collectively searches PDF documents stored separately, such as regulations and notices, and presents the answer along with the corresponding pages as evidence. This reduces the time spent searching for information.

Consideration for Accuracy and Evidence Presentation Instead of generative AI creating answers independently, it employs a mechanism that clearly indicates the relevant sections of the source documents. This minimizes hallucinations (AI generating information not based on facts) and is designed with consideration for the accuracy and clarity of evidence required by financial institutions.

Future Outlook: Zero Operational Errors and Shift to Value-Added Operations

In the future, by further promoting the AI knowledge search system, we will enhance the psychological safety of employees and build a system that allows them to concentrate on customer interactions. The time previously spent on inquiry responses will be allocated to more advanced proposal-based operations and building relationships with regional customers, thereby enhancing added value as a regional financial institution.

Helpfeel will continue to support Kirayaka Bank's further operational advancement and its challenge to create regional added value by providing its AI knowledge search system.

Purpose: Kirayaka Bank Internal AI Knowledge Search System

Search Target: Total of 10,000 pages of PDFs including regulations and notices (initial implementation)

About "Intent Prediction Search 3," an AI Knowledge Search Function Utilizing RAG Technology

"Intent Prediction Search 3" is an innovative search system that combines Helpfeel's proprietary search technology "Intent Prediction Search" with RAG technology. It predicts search intent from users' ambiguous queries and presents optimal answers with supporting evidence from internal documents such as regulations, specifications, and FAQs. It clearly indicates the relevant PDF pages, enabling quick and accurate access to the desired information. Furthermore, it automatically reflects content changes upon document revisions, preventing knowledge management from becoming siloed. It creates an environment where the latest information is shared across the entire organization, transforming knowledge that was dependent on individuals into a shared organizational asset.

"AI Knowledge Data Platform" Accelerating AI Utilization in Companies

The key to unlocking the true value of AI lies in the quality of the "knowledge data" that AI references. Knowledge data refers to information assets that organize and structure dispersed business knowledge within a company, such as FAQs, manuals, and interaction logs, into a format that AI can utilize.

"Helpfeel" is an AI knowledge data platform that transforms a company's internal information into an "AI Ready knowledge base." Centered around this knowledge base, it supports a wide range of applications, including customer support via FAQs and AI agents, operator assistance, and VOC analysis. By starting with knowledge, it enhances corporate decision-making and customer experience, contributing to sustained competitiveness.

It is currently implemented in over 900 sites (as of April 2026) primarily among domestic enterprise companies in sectors such as finance, infrastructure, manufacturing, and retail.
