NeuroGenesysWhich EU AI Act rules apply to your system?
The EU AI Act sorts AI into prohibited practices, high-risk systems, transparency duties and minimal risk, with separate rules for general-purpose AI models. Answer a few questions to see your likely tier, what each obligation requires with its article, and when it applies under the 2026 Digital Omnibus timeline.

Scope
Is the system placed on the EU market or put into service in the EU, or is its output used in the EU?
Art. 2(1) · Applies to providers outside the EU too, if their system's output is used in the EU.

Questions
When do the EU AI Act high-risk rules apply?
After the Digital Omnibus (Regulation (EU) 2026/1744, in force 27 July 2026): from 2 December 2027 for stand-alone high-risk systems in Annex III areas such as hiring, credit scoring and education, and from 2 August 2028 for AI built into products like medical devices, machinery and toys.
What makes an AI system high-risk under the AI Act?
Either it is a safety component of, or itself, a product under EU product law that needs third-party conformity assessment (Annex I), or it is used in one of the Annex III areas, such as biometrics, critical infrastructure, education, employment, essential services, law enforcement, migration or justice. Annex III systems can escape the tier under Article 6(3) if they only do narrow or preparatory tasks and don't profile people.
Do chatbots have to disclose they are AI?
Yes. Under Article 50(1), applying since 2 August 2026, people must be told they are interacting with an AI system unless it is obvious. Generated audio, images, video and text must also be marked in a machine-readable way (Article 50(2)).
Is emotion recognition banned in the EU?
In workplaces and education, yes: Article 5(1)(f) prohibits inferring emotions there except for medical or safety reasons, and it has applied since 2 February 2025. Elsewhere emotion recognition is allowed but carries transparency duties, and biometric emotion recognition is a high-risk use.
Does the AI Act apply to companies outside the EU?
Yes. It covers providers placing AI on the EU market and any provider or deployer whose system's output is used in the EU, wherever they are based (Article 2(1)).
