Trustyyle Co., Ltd., which operates the co-working and community space 'HR Library' for HR professionals, released the 'HR AI Utilization Case Study Report – Key Success Factors from 100 Domestic and International Cases' in May 2026, based on a comprehensive survey of HR AI utilization cases both domestically and internationally.
This report meticulously selects 100 cases with significant practical implications for the HR domain from 300 potential domestic and international cases. It categorizes them into 8 areas: recruitment, employee services, placement, evaluation, organizational development, labor management, AI talent development, and non-engineer development. For each, it organizes 'how AI is used in which HR domain' based on publicly available information from companies.
Background of the Report's Publication
Amidst the rapid spread of generative AI and AI agents, HR is also seeing AI utilization begin in various tasks such as inquiry response, recruitment communications, drafting evaluation comments, survey analysis, internal talent marketplaces, and AI talent development.
However, HR professionals on the ground express concerns like, 'I don't know what tasks other companies are actually using AI for,' 'It's hard to judge how much to delegate to AI,' and 'I'm anxious about how to use AI in areas requiring human judgment, such as recruitment, evaluation, and placement.'
With the mission 'Pioneer the future through collaboration and learning' and 'Bring HR professionals to every organization,' the HR Library has operated a place for HR professionals to learn from each other and share practical knowledge without isolation. This report was created so that HR AI utilization is not just a topic for a few advanced companies, but rather a resource that HR and management in various companies can use to review their own operations.
Features of the Report
1. 100 cases with high practical implications carefully selected from 300 domestic and international cases
This report comprehensively organized approximately 300 potential HR AI utilization cases based on publicly available cases, company announcements, implementation examples, and media articles from both Japan and abroad.
From these, 100 cases were carefully selected based on their specificity as HR tasks, verifiability of public information, whether human confirmation/judgment remained, and their replicability for other companies.
2. Organized by 8 HR domains
The cases presented are classified into the following 8 domains:
Inquiry response/employee services
Recruitment/selection support
Talent management/placement
Evaluation/1-on-1/manager support
Organizational development/surveys
Labor management/employee relations/onboarding
AI talent development/utilization retention
Non-engineer development
Each domain is structured to allow comparison of tasks where AI is easily utilized, the resulting outcomes, and key points requiring human confirmation.
3. Each case organized to be 'readable as a business process'
Each case is organized not merely as an introduction to company names or tools, but by the following 5 items:
Problem situation
AI utilization part
Remaining human response
Outcomes
Characteristics of this case
The workflow is organized based on publicly available information so that even non-engineer HR professionals can read it by relating it to their own business situations.
Key Takeaways from 300 Cases on HR AI Utilization
What emerged from a cross-sectional view of 100 cases is that the essence of HR AI utilization is not merely time-saving or automation. While speeding up tasks with AI is important, what's more crucial is what to do with the time and perspective gained. The success of AI utilization depends on whether the freed capacity can be reinvested into dialogue with employees, manager support, discovery of organizational issues, and HR activities that advance the business.
This report organizes key points such as:
HR AI is a tool to implement 'desired organizational states' before merely speeding up tasks.
Companies advanced in AI utilization separate the scope delegated to AI from what requires human confirmation.
In successful cases, AI is used for 'preparation before judgment' such as inquiries, recruitment communications, and drafting evaluations.
The ability to reinvest the capacity freed by AI into interviews, dialogues, training, and organizational improvement determines outcomes.
AI utilization is not just tool implementation but an initiative to redesign workflows and human roles.
Examples of Covered Areas
Inquiry response/employee services
This section organizes cases where AI assists in searching for evidence and drafting answers for inquiries from employees regarding vacations, benefits, regulations, and procedures. A pattern is observed where AI prepares for routine inquiries, while HR confirms matters involving interpretation of rules, exceptional handling, and issues with significant impact on individuals.
Recruitment/selection support
This section includes cases where AI assists with application reception, candidate communications, interview scheduling, and organizing interview records. Humans handle hiring decisions and explanations to candidates, while AI is used for preparation before candidate interaction and reducing communication load.
Evaluation/1-on-1/manager support
This section organizes cases assisting with drafting evaluation comments and feedback, organizing 1-on-1 records, and supporting managers in improving their expression. AI does not make evaluations, but rather assists managers in organizing materials and confirming phrasing before communicating with individuals.
AI talent development/utilization retention
AI training, in-house AI academies, practical workshops.
