Article 50 compliance checklist
Article 50 creates transparency duties for providers and deployers of certain AI systems. Work through the controls below by role, mark what is done, and keep the evidence each control produces.
Content last reviewed 2026-08-03
Indicative guidance only — not legal advice
This tool summarises official EU materials for information purposes. It does not constitute legal advice, completing it does not establish compliance, and borderline situations turn on specific facts. Have counsel review your own circumstances.
The AI Omnibus did not postpone Article 50
The AI Omnibus postponed the high-risk regime — Annex III systems to 2 December 2027 and Annex I systems to 2 August 2028 — but it did not postpone Article 50. The transparency duties still apply from 2 August 2026. The Omnibus did amend Article 50(2), adding the limited marking transition to 2 December 2026 below.
What non-compliance costs
Up to €15 million or 3% of worldwide annual turnover
- For undertakings, the applicable ceiling is the higher of the two figures.
- For SMEs and start-ups, Article 99(6) inverts the calculation: the ceiling is the lower of the two figures.
- For EU institutions, bodies and agencies, the Commission fact page states fines up to €750,000; the EDPS is the competent authority.
- Enforcement is decentralised — national market surveillance authorities handle Article 50 in the first instance.
How to use this checklist
Start with the legal and compliance controls: the first question is not “do we use AI?” but which business units are providers, which are deployers, and which outputs reach people directly. A single company is often both.
Filter by role to give each team its own working list. Your progress is saved in this browser only — nothing is transmitted or stored on a server.
Article 50 does not replace the GDPR. For emotion recognition and biometric categorisation, a notice is necessary but not sufficient: a lawful basis, and possibly a DPIA, are still required.

Complete Article 50 scoping and role allocation
Timeline: Immediate
Why
Determine where the company is a provider, a deployer, or both. The fastest triage question is not “Do we use AI?” but which business units are providers, which are deployers, and which outputs reach people directly.
Actions
- Build a use-case register covering every AI system that reaches people.
- Assign a provider or deployer role per workflow.
- Identify EU-facing outputs, including non-EU products whose outputs are used in the Union.
- Set a RACI by business unit.

Decide on the Code of Practice strategy
Timeline: Within days
Why
Choose the simplest evidence model. The Code of Practice on Transparency of AI-Generated Content is voluntary, but the Commission and the AI Board have assessed it as an adequate method for demonstrating compliance with the marking and labelling duties.
Actions
- Determine whether to sign the Code for the relevant provider and/or deployer functions.
- If not signing, define the “alternative adequate means” evidence package — non-signatories remain free to comply otherwise but should expect to prove adequacy more directly.

Why
Prepare for regulator requests and internal audit. Enforcement is decentralised: national market surveillance authorities will mainly enforce Article 50.
Actions
- Centralise screenshots, scripts, metadata specs, exception decisions, accessibility reviews, vendor attestations, and publication review records.
- Retain dated copies of control changes made before 2 August, and before 2 December for eligible legacy systems.

Enable direct-interaction disclosure by design
Timeline: Immediate — complete before 2 Aug 2026
Why
Systems intended to interact directly with natural persons must be designed so people are informed they are interacting with AI, before market placement or service launch.
Actions
- Identify all systems that directly converse with natural persons.
- Decide whether any “obvious interaction” position is defensible — the Commission says this exception should be interpreted restrictively.
- Implement a default greeting, banner, or voice disclosure in every channel and locale.
- Confirm accessibility support.

Implement machine-readable provenance or marking
Timeline: Immediate for live systems; eligible legacy systems by 2 Dec 2026
Why
Synthetic audio, image, video, or text outputs must be machine-readable and detectable as artificially generated or manipulated. Solutions should be effective, interoperable, robust, and reliable so far as technically feasible.
Actions
- Turn on automated marking for synthetic text, image, audio, and video where in scope.
- Document technical feasibility limits by modality.
- Test detectability after export, compression, API delivery, and platform upload.

Separate in-scope from out-of-scope outputs
Timeline: Immediate; refresh monthly
Why
Avoid over-labelling some content while missing others. Source code, short symbol strings, machine-to-machine outputs and some closed-loop industrial outputs fall outside the marking duty.
Actions
- Classify source code, short strings, machine-to-machine outputs, draft industrial outputs, standard-editing functions, and final consumer-facing outputs.

Turn on deepfake labelling
Timeline: Immediate — complete before 2 Aug 2026
Why
Image, audio, or video content constituting a deepfake must be disclosed as artificially generated or manipulated. Visible or audible disclosure is required — machine-readable marks alone are not enough.
Actions
- Identify deepfake use cases across ads, training, customer support, social media, entertainment, investor and brand content.
- Place visible or audible notices at first exposure.
- Do not rely solely on provider metadata.

Label public-interest text, or control the review exemption
Timeline: Immediate
Why
AI-generated or manipulated text published to inform the public on matters of public interest must be disclosed, unless it underwent substantive human review and a person holds editorial responsibility. Spell-checking or grammar checks are not enough.
Actions
- Flag content involving politics, public health, law, justice, security, environment, consumer safety, or major economic, scientific and cultural debate. The Regulation says only “matters of public interest” — this list comes from the Commission guidelines and is illustrative, not exhaustive. A topic outside it is not automatically outside scope.
- Either label it, or route it through a substantive human review and editorial responsibility workflow.

Implement emotion-recognition and biometric exposure notices
Timeline: Immediate
Why
People exposed to an emotion recognition or biometric categorisation system must be informed it is operating. Article 50(3) also expressly requires personal data to be processed in accordance with the GDPR — a notice is necessary but not sufficient.
Actions
- Map kiosks, surveillance systems, workplace analytics, access control, fraud tools, and customer analytics using such functions.
- Post notices at first exposure.
- Align with the privacy notice and the lawful-basis analysis; assess whether a DPIA or DPO involvement is required.

Timeline: Critical fixes before 2 Aug 2026; eligible legacy fixes before 2 Dec 2026
Why
Provider-side marking is only meaningful if it survives delivery. Many pipelines silently strip provenance information.
Actions
- Test whether the CDN, CMS, DAM, social tools, image processors, and transcoders strip marks.
- Log failures.
- Implement preservation rules, or fallback visible labelling.

Actions
- Adopt a style rule for where labels appear on articles, videos, audio players, social posts, and campaign assets.
- The Commission provides three optional EU icons for labelling AI-generated content. Use them where helpful, but pair an icon with plain-language text as the safer default unless usability testing shows icon-only disclosure is clearly understood.

Sample disclosure wording
Article 50 does not prescribe exact wording — it requires the information to be clear, distinguishable, accessible, and given by the first interaction or exposure. These are illustrative, drafted to the legal standard rather than copied from an official EU template.
Direct AI interaction
“You are interacting with an AI system.”
Shortest defensible version for chat, voice, kiosk, or avatar experiences. Use at the start of the interaction.
Direct AI interaction, with escalation
“You are interacting with our AI assistant. A human can review or take over where available.”
The second sentence is optional but often good UX. The first sentence carries the Article 50 function.
Emotion recognition or biometric categorisation
“This service uses AI-based emotion recognition or biometric categorisation during operation.”
Article 50(3) does not itself require the purpose to be stated, but a GDPR privacy notice may require broader information.
Deepfake video or audio
“This content has been artificially generated or manipulated using AI.”
Put it on the player, opening frame, caption, or audible introduction. Do not rely only on hidden metadata.
AI-generated public-interest text
“This text was generated or manipulated using AI and was not subject to human editorial review.”
Use where the human-review exemption is not met.
Voluntary disclosure for exempt text
“This publication used AI assistance and was reviewed by human editors.”
Not legally required where the exemption applies. Many organisations still use it as a trust measure — a policy choice, not an Article 50 mandate.
Step 3 · Edge cases
Scenario library
Twenty concrete situations — including the edge cases that trip teams up: legacy systems, employees, non-EU entities, artistic works, internal-only text, law-enforcement uses. Each card states what applies and the common traps.
Provider situations
Customer-facing chatbot or voice assistant
You build or offer a system intended to interact directly with natural persons.
What applies
- Art. 50(1): design the disclosure into the system before market placement — default greeting, banner or voice prompt, in every channel and locale.
- Disclosure at the latest at the first interaction.
Common traps
- The “obvious AI interaction” exception is interpreted restrictively — document any reliance on it.
- A disclosure that exists in one channel but not in an embedded widget or API wrapper is a gap.
Provider situations
Generative AI product — image, audio, video or text
Your system produces synthetic content within Article 50(2).
What applies
- Machine-readable marking, detectable as artificially generated or manipulated.
- Solutions effective, interoperable, robust and reliable so far as technically feasible — document feasibility limits by modality.
Common traps
- Marks that do not survive export, compression, API delivery or platform upload.
- Relying on marking alone where a deployer also needs a visible disclosure.
Provider situations
Assistive or standard-editing features only
Your AI feature retouches, corrects or adjusts content without substantially altering the input.
What applies
- No marking duty where the input is not substantially altered (standard-editing exception).
Common traps
- The line between “standard editing” and generation is factual — document the analysis per feature, and revisit when features gain generative capability.
Provider situations
System placed on the market before 2 August 2026
An in-scope system predates the application date.
What applies
- Transition until 2 December 2026 — but only for the Art. 50(2) machine-readable marking duty.
- All other Article 50 duties apply from 2 August 2026.
Common traps
- Treating the grace period as a general postponement — it is not.
- Systems placed on the market on or after 2 August 2026 get no transition at all.
Provider situations
B2B, machine-to-machine or closed-loop industrial outputs
Outputs are source code, short symbol strings, machine-to-machine data, or non-final industrial outputs.
What applies
- These can fall outside the Art. 50(2) marking duty; the guidelines also describe a narrow B2B or industrial exemption under stated conditions.
Common traps
- The exemption is narrow and conditional — keep a documented rationale per output type, signed off by an owner.
- An “industrial” output that later reaches consumers re-enters scope.
Provider situations
Non-EU provider with users in the Union
You have no EU establishment, but your system's outputs are used in the EU.
What applies
- Article 2 scope: non-EU providers and deployers can still be in scope where outputs are used in the Union.
Common traps
- Assuming geography alone puts you out of scope — map where outputs actually land, not where servers sit.
Deployer situations
Vendor chatbot embedded on your site or app
You deploy a third-party conversational system under your authority.
What applies
- The provider builds the disclosure; you need operational controls so it actually appears in use — in your theme, your locales, your channels.
Common traps
- A custom skin or integration that hides the provider's disclosure.
- No contractual clarity on who answers a regulator's question.
Deployer situations
Deepfake in marketing, training or entertainment content
You publish AI-generated or manipulated image, audio or video that appears real.
What applies
- Art. 50(4): visible or audible disclosure at first exposure — player overlay, opening frame, caption or audible introduction.
Common traps
- Relying on the provider's hidden metadata alone — it does not satisfy the visible-disclosure duty.
- Labels that disappear when content is downloaded, shared, embedded or reposted.
Deployer situations
Evidently artistic, satirical or fictional work
The deepfake is part of a film, satire, fiction or analogous work.
What applies
- Disclosure may be given in a way that does not hamper enjoyment of the work.
Common traps
- Over-claiming the allowance for content that is not evidently artistic — classify and document each asset.
Deployer situations
AI-drafted articles on public-interest topics
You publish AI-generated text informing the public on politics, health, law, justice, security, environment, consumer safety or major public debate.
What applies
- Label the text — or run it through substantive human review with a person holding editorial responsibility.
Common traps
- Spell-checking or grammar passes do not qualify as substantive review.
- “Editorial responsibility” left undefined — name the person.
Deployer situations
Internal-only AI text, never published
AI drafts internal reports, memos or emails that are not published to inform the public.
What applies
- The Art. 50(4) text duty targets text published to inform the public on matters of public interest — purely internal documents are generally outside it.
Common traps
- Internal content that later gets published — build the labelling check into the publication step, not the drafting step.
Deployer situations
Emotion recognition in HR, sales or support
Workplace analytics, interview tools or call-centre systems infer emotions.
What applies
- Art. 50(3): inform exposed persons the system is operating, at first exposure.
- GDPR in parallel: lawful basis, transparency, and likely a DPIA — a notice alone is not compliance.
Common traps
- Forgetting that other AI Act chapters (including high-risk duties) may apply on top of Article 50.
Deployer situations
Biometric categorisation in physical spaces
Kiosks, retail analytics or CCTV-linked systems categorise people on biometric data.
What applies
- Art. 50(3) notice at first exposure — posted where people actually see it.
- Large-scale monitoring of publicly accessible areas is a typical DPIA trigger under the GDPR.
Common traps
- A notice hidden in a privacy policy no one sees before exposure.
Deployer situations
Content created before 2 August 2026
Your archives contain AI-generated content from before the application date.
What applies
- No retroactive labelling is required; the Commission encourages voluntary labelling where feasible.
Common traps
- Re-publishing or re-cutting old content after 2 August 2026 — treat that as a new publication decision.
Special cases
You are both provider and deployer
One business unit ships an AI product; another uses third-party AI tools.
What applies
- Allocate the role per use case in a single register, and assign each Article 50 duty accordingly.
Common traps
- Duties falling into the gap between two teams that each assume the other owns them.
Special cases
Employees using AI tools at work
Staff use AI systems in the course of their job.
What applies
- Employees acting under the authority and control of a legal entity are generally not separate deployers — the company holds the duties.
Common traps
- Shadow AI: tools adopted by teams without appearing in the company's use-case register.
Special cases
EU institutions, bodies and agencies
The provider or deployer is an EU institution.
What applies
- The European Data Protection Supervisor is the competent authority; the Commission fact page notes fines up to €750,000.
Special cases
SMEs and start-ups
You are a small company with limited compliance resources.
What applies
- The duties are identical — size does not change what Article 50 requires.
- Only the arithmetic of the ceiling changes. For undertakings generally, the ceiling is the higher of €15 million or 3% of worldwide annual turnover; Article 99(6) inverts this for SMEs and start-ups, making it the lower of the two.
Common traps
- Reading the SME rule as a lighter obligation rather than a lower ceiling — the duties themselves are unchanged.
- Deferring scoping because of size — the register and front-end notices are the minimum viable controls.
Special cases
Content distributed on a very large online platform
Your AI-generated content is published on a designated very large online platform or search engine.
What applies
- Article 50 duties continue to apply to you as provider or deployer.
- The platform carries its own DSA systemic-risk obligations for generative content, including marking where feasible — those duties sit on the platform, not on you, and do not discharge your Article 50 disclosure.
- Where the same entity provides both the system and the underlying general-purpose model, or the system is integrated into a designated platform, the AI Office has a specific enforcement role alongside national authorities.
Common traps
- Assuming a platform's automatic AI label satisfies your own deployer disclosure — it does not.
Special cases
System built on your own GPAI model, or integrated into a designated platform
The same entity provides both the system and the general-purpose model, or the system is integrated into a designated very large online platform or search engine.
What applies
- The AI Office has a specific enforcement role in these configurations, alongside national market surveillance authorities.
Special cases
Law-enforcement uses
The system is used for the detection, prevention, investigation or prosecution of criminal offences.
What applies
- Specific exceptions exist across Art. 50(1)–(4), under the conditions stated in each paragraph.
Common traps
- The exceptions are conditional, not a blanket carve-out — document the reliance conditions for each use.
