Priv Tech Inc. (Headquarters: Minato-ku, Tokyo; Representative Director: Daisuke Nakamichi; hereinafter "Priv Tech") has commenced the provision of "AI Risk Checker," a new product that evaluates the risks of generative AI (LLM), as part of its "AI Risk Management Service" which supports risk management in corporate AI utilization. This tool is planned for sequential function expansion in the future.
■ Background and Purpose
In recent years, while the corporate use of generative AI has rapidly expanded, addressing AI-specific risks such as hallucinations (generation of misinformation), inappropriate responses, information leaks, and brand damage has become a challenge. Particularly, as cases of integrating LLMs into corporate activities, such as customer service chatbots and internal AI assistants, increase, more companies are facing challenges like "not knowing how much to trust AI" and "lacking established evaluation criteria and checking systems."
Furthermore, Japanese companies require not only simple correctness judgments but also responses to honorific expressions, brand tone, and unique Japanese ethical values, which overseas tools often fail to cover adequately.
Against this backdrop, Priv Tech has leveraged its expertise in AI governance support to launch the "AI Risk Checker" AI risk assessment tool.
■ Service Features
"AI Risk Checker" is an LLM evaluation system that analyzes corporate websites, internal regulations, FAQs, and manuals, then automatically generates and evaluates "dedicated high-difficulty test questions" based on the company's specific risks. It comprehensively verifies hallucinations, biases, inappropriate expressions, and brand tone deviations that are difficult to find with standard tests, visualizing the AI's weaknesses.
One of its key features is the ability to automatically generate test data tailored to each company's risks.
For example, it analyzes points where LLMs are prone to misunderstanding or confusion, such as exception conditions in regulations or updated internal rules, and generates challenging questions. This allows for efficient identification of potential risks that cannot be found through regular QA tests.
Additionally, by adopting "LLM as a Judge" (automated evaluation by AI), it can conduct large-scale tests in a short time, which would be difficult for human evaluators. It enables quantitative and continuous evaluation, including not only the factual accuracy and relevance of responses but also their suitability for Japanese honorific expressions and brand tone.
Key evaluation items are as follows:
【Reliability】
・Hallucinations (factuality)
・Response relevance
・Fidelity (consistency with reference information)
【Safety】
・Bias detection
・Harmful expressions
・Prompt injection resistance
【Quality】
・Task completion degree
・Suitability for brand tone and honorific expressions
Furthermore, by continuously checking even after internal regulation revisions or model updates, it can be used as a "health check for AI," enabling early detection of AI quality degradation or information inconsistencies, and supporting the establishment of a continuous AI improvement cycle.

■ Future Developments
As the business utilization of generative AI accelerates, companies are increasingly required to manage not only the convenience but also the safety, accountability, and continuous risk of AI.
Priv Tech will further strengthen AI governance system establishment and AI risk management support for Japanese companies through the expansion of "AI Risk Checker" functions and continuous monitoring support.
Priv Tech will continue to support the safe and sustainable utilization of generative AI by companies.
