AI disclosure requirements in Sweden: what applies since 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.
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.
Common questions
Is Sweden's AI supervision ready for 2 August 2026?
That is the plan on record: the proposal names PTS as main market surveillance authority within an eleven-authority structure, and the national law and ordinance are targeted to take effect by 2 August 2026, the same day Article 50 starts applying. Plan for supervision from the application date; there is no grace period.
Does IMY or PTS handle a chatbot-disclosure complaint?
Under the proposal PTS leads market surveillance, so Article 50 transparency issues route there; IMY remains competent for the personal-data dimension of the same system under the GDPR. In practice a poorly disclosed chatbot that processes personal data can be complained about through either door.
