AI disclosure requirements in Sweden: what applies from 2 August 2026

The EU AI Act's transparency obligations are a Union-wide regulation, so the substance is the same in Sweden as everywhere in the EU: from 2 August 2026, AI systems that interact with people must disclose they're AI, synthetic media must carry machine-readable marking, and deepfakes and certain AI-generated public-interest text must be labeled. What differs country by country is who enforces it, in what language your users encounter it, and how quickly complaints turn into questions — which is what this page covers for Sweden.

Enforcement in Sweden

Sweden's implementing framework was in its final stretch at the time of review: the government proposal designates the Swedish Post and Telecom Authority (PTS) as the main market surveillance authority within a structure of eleven market surveillance authorities and two notifying authorities, with the national AI law and ordinance targeted to take effect by 2 August 2026. The data protection authority IMY endorsed the proposal in its February 2026 consultation response (while arguing it should hold sole responsibility for prohibited-practice surveillance). Article 50 applies from 2 August 2026 with the EU penalty ceiling of €15M or 3% of worldwide turnover.

The four duties, as they show up on your site

• Article 50(1) — chatbot disclosure. Any AI system interacting with visitors must make that clear no later than the first interaction, in a clear and distinguishable way. A line in your terms doesn't satisfy it.
• Article 50(2) — machine-readable marking. AI-generated audio, images, video, and text must be marked in a machine-readable, detectable format. For generative systems already on the market before 2 Aug 2026, this specific duty has a transition until 2 Dec 2026 — the rest does not.
• Article 50(3) — emotion recognition & biometric categorisation. People exposed must be informed the system is operating.
• Article 50(4) — deepfake and AI-text labels. Visible disclosure for deepfakes, and for AI-generated or manipulated text published to inform the public on matters of public interest.

Sweden-specific practicalities

• PTS as lead means Sweden's supervision lands at a technically fluent regulator — expect comfort with machine-readable checks, not just paperwork review
• IMY stays in the picture wherever personal data is processed, and its consultation stance signals appetite for an active AI role
• Sweden's e-commerce and SaaS sectors are unusually English-first — but a .se storefront served in Swedish should still disclose in Swedish
• Timing matters here: the national framework is targeted to be live exactly when Article 50 starts applying, so assume no enforcement gap

Disclosure language should match your user-facing language. For a site serving Sweden in Swedish, a first-message line such as "Du chattar med en AI-assistent" (you're chatting with an AI assistant) is the pattern to aim for — at first interaction, not tucked into villkor.
