The EU AI Act · article by article

Every obligation, one article at a time.

The guides below take the Act in its own order: what each article requires, who it applies to, what to document, and when it applies. The dates are the ones in force after the Digital Omnibus; the check at the end tells you which of these articles apply to your system.

Which of these articles apply to your system?

Describe it in a few sentences. You get a risk tier, the applicable articles and the governance gaps in seconds, with no account. Or name your website and queue one visit: one question, one record.

One automated visit to the public site, as a first-time visitor would see it: does the chat surface say it is an AI, and does it say so when asked? Nothing is analysed here and now.

This analysis is generated by Vigilia, an AI system.

The rulebook self-check

Article by article, from what you describe.

The free self-check maps what you describe against every applicable article and returns a risk tier, the articles that govern it and the governance gaps — a gap analysis, never a legal determination. The register does the other half: one visit to the AI systems organisations actually run, one record, open to reply.
