The EU AI Act and AI assistants: what applies, and when.

The AI Act is the EU’s law on artificial intelligence. Most of it is about high-risk uses such as hiring or credit, but parts apply to every chatbot and assistant.

In short. For an everyday AI assistant, three parts of the AI Act matter. You must be told you are talking to an AI, unless it is obvious, from August 2026. Nine practices are banned, from harmful manipulation to exploiting people’s vulnerabilities. And the companies that build the large models behind assistants have had duties since August 2025. Rules for high-risk uses follow in December 2027 and August 2028, after the 2026 “omnibus” moved them back.

The timeline

DateWhat applies
1 August 2024The AI Act enters into force
2 February 2025Banned practices 1 to 8; duties on AI literacy
2 August 2025Governance rules; duties for general-purpose AI models
2 August 2026Most of the Act, including the transparency rules
December 2026A ninth ban, added by the 2026 omnibus
2 December 2027High-risk uses in sensitive areas, such as employment, education and biometrics
2 August 2028High-risk AI built into regulated products

The “AI omnibus”, a law to simplify the AI Act, was proposed on 19 November 2025, agreed on 7 May 2026 and entered into force on 27 July 2026; it moved the high-risk dates to those above.

What it means for an AI you talk to

Your data rights come from a different law, the GDPR: your data rights with an AI assistant.

What may come next

A proposal is on the table for AI companions in particular: the Commission’s KIDS Act would bar AI companions and chatbots that minors can use from imitating a relationship in ways likely to create emotional dependency. It is a proposal, not law: the KIDS Act and age limits.

How Lychnos is designed

Lychnos tells you it is an AI and does not pretend to be a person. It asks before it acts, and every action is logged. It is in development; why we build in Europe: a European AI assistant.
