Is Your AI Tool High-Risk? A Classification Guide

Understanding AI Risk Classification

Both the UK and EU regulatory frameworks categorize AI systems by risk level. Understanding where your tools fall is essential for knowing what compliance measures apply.

The Risk Categories

Minimal Risk

Most AI applications fall here. Examples:

• Spam filters
• AI-powered search
• Grammar and writing assistants
• Basic chatbots for FAQs

Requirements: Minimal—just general good practices.

Limited Risk

AI with specific transparency obligations:

• Chatbots that interact with users
• Emotion recognition systems
• Deepfake generators
• AI content creation tools

Requirements: Must disclose AI involvement to users.

High Risk

AI used in sensitive areas:

• Employment and recruitment decisions
• Credit scoring and lending
• Educational assessment
• Healthcare diagnostics
• Law enforcement applications

Requirements: Extensive documentation, testing, and oversight.

Unacceptable Risk

Banned AI applications:

• Social scoring by governments
• Real-time biometric surveillance (with exceptions)
• Manipulation of vulnerable groups
• Subliminal manipulation

Requirements: Prohibited entirely.

Assessment Criteria

To classify your AI use, consider:

1. Decision Impact

• Does the AI make or influence significant decisions?
• Could errors cause harm to individuals?
• Are vulnerable groups affected?

2. Sector Context

• Is the AI used in a regulated sector?
• Are there sector-specific AI rules?
• What do relevant regulators say?

3. Autonomy Level

• How much human oversight exists?
• Can humans override AI decisions?
• Is the AI advisory or determinative?

4. Data Sensitivity

• Does the AI process special category data?
• Is personal data involved?
• What's the scale of data processing?

High-Risk Compliance Requirements

If your AI use is classified as high-risk, you must:

• Implement a quality management system
• Maintain detailed technical documentation
• Enable logging and traceability
• Ensure human oversight capabilities
• Meet accuracy, robustness, and cybersecurity requirements
• Conduct conformity assessments

Practical Steps

1. Audit your AI tools: List every AI tool you use
2. Classify each tool: Use the criteria above
3. Document your assessment: Keep records of your classification decisions
4. Implement appropriate measures: Match compliance efforts to risk level
5. Review regularly: Reassess as your AI use evolves

Most solopreneurs will find their AI use falls into minimal or limited risk categories, but it's essential to verify this through proper assessment.
