Trustyyle Co., Ltd., which operates "HR Library," a coworking and community space for HR professionals, released in May 2026 an "HR AI Utilization Case Study Report - Key Success Factors from 100 Domestic and International Cases," which cross-sectionally surveyed HR AI utilization cases both domestically and internationally.
This report carefully selects 100 cases with significant practical implications in the HR domain from 300 candidate cases worldwide. These cases are categorized into 8 areas: recruitment, employee services, placement, evaluation, organizational development, labor management, AI talent development, and non-engineer development. It organizes "how AI is used and in which HR areas" based on public information from each company.
Due to the high demand after its initial release, Ver2, an illustrated enhanced edition, has now been published. The detailed illustrations for each case now provide more specific insights for companies considering implementation.
Background to the Report's Publication
As the utilization of generative AI and AI agents rapidly expands, AI application is also beginning in various HR operations, including inquiry handling, recruitment communication, drafting evaluation comments, survey analysis, internal talent marketplaces, and AI talent development.
On the other hand, HR personnel on the ground voice concerns such as, "We don't know which specific tasks other companies are using AI for," "It's difficult to judge how much we should entrust to AI," and "We are anxious about how to use AI in areas requiring human judgment, such as recruitment, evaluation, and placement."
Under the philosophy of "Pioneering the future through learning with peers" and "Professional HR for every organization," HR Library has operated a platform where HR professionals can learn from each other by bringing together practical knowledge without feeling isolated. This report was created so that HR AI utilization is not just a topic for a few advanced companies but can be used by HR and management in various companies as material to review their own operations.
Features of the Report
1. Carefully selected 100 cases with high practical implications from 300 domestic and international cases.
This report cross-sectionally organized approximately 300 potential HR AI utilization cases based on public examples, company announcements, implementation cases, and media articles from Japan and abroad.
From these, 100 cases were carefully selected based on the specificity of HR operations, the verifiability of public information, whether human confirmation/judgment remained, and whether other companies could use them as reference.
2. Organized HR areas into 8 categories.
The featured cases are classified into the following 8 areas:
Inquiry Handling & Employee Services
Recruitment & Selection Support
Talent Management & Placement
Evaluation, 1-on-1s & Manager Support
Organizational Development & Surveys
Labor Management, Employee Relations & Onboarding
AI Talent Development & Utilization Retention
Non-Engineer Development
Each area is structured to allow comparison of tasks where AI is easily utilized, outcome patterns, and points that require human confirmation.
3. Each case is organized in a "business-readable" format. Clarity is significantly improved in the illustrated enhanced edition.
Each case is not merely an introduction of company names or tool names but is organized according to the following 5 items:
Problem Situation, AI Utilization Part, Remaining Human Response, Outcome, Features of this Case
Even non-engineer HR personnel can relate to their own business situations. The workflow is organized based on public information, and the illustrated enhanced edition provides even more detailed and easy-to-understand diagrams.

Key points of HR AI utilization seen from 300 cases
What emerged from a cross-sectional view of 100 cases is that the essence of HR AI utilization is not merely about saving time or automation. While speeding up operations with AI is important, what is more crucial is how that newly created time and perspective are used. The success or failure of AI utilization hinges on whether the freed capacity can be reinvested into dialogue with employees, manager support, discovery of organizational issues, and HR activities that drive business forward.
This report organizes key points such as:
・HR AI is a tool to implement "desired organizational states" before merely accelerating tasks.
・Companies advanced in AI utilization separate the scope entrusted to AI from the scope requiring human confirmation.
・In successful cases, AI is positioned for "preparation before judgment," such as inquiries, recruitment communication, and drafting evaluations.
・Success depends on whether the capacity created by AI introduction can be redirected to interviews, dialogues, training, and organizational improvements.
・AI utilization is not about tool implementation but an initiative to redesign workflows and human roles.
Examples of Featured Areas
Inquiry Handling & Employee Services
Cases are organized where AI supports evidence search and draft answer creation for employee inquiries regarding leave, benefits, regulations, and procedures. A pattern is observed where AI prepares responses for routine inquiries, while HR confirms matters related to interpreting rules, handling exceptions, and issues with significant impact on individuals.
Recruitment & Selection Support
Cases are featured where AI supports application reception, candidate communication, interview scheduling, and organizing interview records. Human personnel are responsible for making hiring decisions and explaining them to candidates, while AI is used for preparing before candidate interaction and reducing communication burdens.
