EU AI Act Compliance Checklist for AI Product Builders (2025)

The EU AI Act became fully applicable in stages through 2025 and 2026. If you build an AI product and have any users in the European Union, you need to understand which obligations apply to you — even if your company is based in the US or elsewhere.

This checklist covers the practical steps for most SaaS and AI product builders.

Does the EU AI Act Apply to You?

The Act applies to:

AI systems placed on the market or put into service in the EU
AI systems whose output is used in the EU

This means geographic location of your company doesn't matter. If you have EU users, you're likely in scope.

Exception: purely personal, non-professional use.

Risk Classification: Which Category Are You?

The Act uses a four-tier risk classification. Your obligations depend on your tier.

Unacceptable Risk (Banned)

Systems used for:

Social scoring by governments
Real-time biometric surveillance in public spaces
Subliminal manipulation that harms users

Action: If your product does any of this, it's prohibited in the EU.

High Risk

Systems used in:

Critical infrastructure
Education and vocational training
Employment and worker management
Access to essential services (credit, insurance)
Law enforcement
Border control
Administration of justice

Action: High-risk systems face strict requirements: conformity assessments, technical documentation, human oversight, accuracy and robustness standards.

Limited Risk (Most SaaS AI Products)

Systems that:

Interact with humans (chatbots, virtual assistants)
Generate synthetic content (text, images, audio, video)
Use emotion recognition or biometric categorization

This is where most AI SaaS products fall.

Minimal Risk

General-purpose tools, AI-enabled spam filters, basic recommendation systems.

Obligations for Limited-Risk Systems

If you run a chatbot, AI writing tool, AI image generator, or similar product, you fall under limited risk. Your obligations are transparency-focused:

1. Disclose that users are interacting with AI

Users must be informed when they're interacting with an AI system — unless it's obvious from the context.

What to add to your UI:

A label or badge indicating "Powered by AI" or "AI assistant"
A note in onboarding that the product uses AI to generate responses

What to add to your privacy policy:

"Our product uses artificial intelligence to generate content and responses. You are interacting with an AI system, not a human."

2. Label AI-generated content

If your system generates images, audio, or video that could be mistaken for real content (deepfakes), you must label it as AI-generated.

For text-only tools, this obligation is lighter — but transparency is still best practice.

3. Disclose emotion recognition (if applicable)

If your system analyzes or infers emotions, users must be informed.

General-Purpose AI Models (GPAI)

If you're building on top of a model like GPT-4 or Claude, you're using a GPAI model. The Act places obligations on the providers of these models (OpenAI, Anthropic, etc.), not on you as a downstream deployer — but you should:

Reference which GPAI model(s) you use in your documentation
Understand the usage policies of your model provider as they relate to compliance

Privacy Policy Additions for EU AI Act Compliance

Your privacy policy should include a section that covers:

AI Transparency (EU AI Act)

[App Name] uses artificial intelligence to provide [describe service]. 
In accordance with the EU AI Act, we disclose that:

- You are interacting with an AI system.
- AI-generated content may not always be accurate and should be reviewed before use.
- [If applicable] Our system makes automated recommendations based on [criteria]. 
  You have the right to request human review of decisions that significantly affect you.

Documentation Requirements

Even for limited-risk systems, it's good practice (and may be required depending on your system's eventual reclassification) to maintain:

System description: What the AI does, what inputs it takes, what outputs it produces
Training data summary: What data was used (if you fine-tune your own model)
Third-party model documentation: Links to the model cards of any GPAI models you use
Human oversight mechanisms: How humans can review or override AI outputs
Incident log: Any cases where the AI produced harmful or inaccurate outputs

Checklist Summary

Use this before launch or when updating your AI product for EU compliance:

Legal documents

[ ] Privacy policy discloses AI usage and which providers receive data
[ ] Privacy policy includes EU AI Act transparency statement
