About "プライオ（PRaiO）"
What is PRaiO
PRaiO is a tool that uses AI to support document screening (entry sheets) in new-graduate hiring. Co-developed by Mynavi Corporation and Mitsubishi Research Institute (MRI), it is built around MRI's HR-specialized AI engine "HaRi." The AI learns from a company's past selection data and entry sheets, then scores each applicant's priority—speeding up and standardizing first-round screening of large applicant pools and reducing recruiters' workload. It has been adopted by more than 800 companies.
PRaiO is not a "take-the-test" aptitude assessment that applicants sit. It is an AI that learns from and analyzes the entry sheets and application data you have collected, on a per-company basis. It differs in both aim and category from take-the-test assessments such as SPI or Mikiwame.
It learns your own "past selections" to assess applicants
PRaiO's core is having the AI learn each company's past hiring criteria to build a diagnostic model unique to that company. Rather than a generic aptitude test, it predicts the priority of new applicants based on the kinds of applicants your company has passed in the past. Before reading through a huge volume of entry sheets from scratch, recruiters can use the AI's assessment to get a sense of prioritization.

How it differs from other hiring-support tools
Even within "hiring × AI," tools that applicants take as an aptitude test differ in role from tools that analyze application data. PRaiO stands out for learning your own past selections to speed up and standardize first-round screening of entry sheets.
| Aspect | PRaiO | Take-the-test aptitude assessment (Mikiwame, etc.) |
|---|---|---|
| What it does | AI assesses ESs and application data | Applicants take a personality / ability test |
| Applicant burden | No extra test (just submit an ES) | Must take a test |
| Data | Learns from your own past selections | Standardized assessment results |
For take-the-test aptitude assessments, Mikiwame AI; for applicant tracking and scouting, PeopleXRecruit; and for labor/HR databases, SmartHR are worth comparing. For companies that want to efficiently screen large volumes of entry sheets in new-graduate hiring, PRaiO is a strong option.
