Paste any ad, post, or marketing copy below. The Disclosure Lie Detector runs heuristics against EU AI Act Article 50 — the AI-disclosure rules in force since August 2, 2026 — and returns a verdict: PASS, FAIL, or UNCLEAR, with the specific article cited for each finding.
⚖️ This is automated guidance, not legal advice. Heuristics can't see your contracts, your intent, or your counsel's opinion.
DisclosureGuard is our AI disclosure compliance platform — automated Article 50 checks across every ad, post, and campaign before they go live. No heuristics homework, no fines.

When ads, reviews, or political posts hide synthetic origins, they bypass the skepticism people apply to machines — the same deception primitive behind phishing and social engineering. Article 50 makes labeling a legal duty, but enforcement starts with detection. This tool scores copy against disclosure heuristics so you can see the lie before you believe it.
Article 50 of the EU AI Act sets transparency and disclosure obligations that apply regardless of risk classification: informing users when they interact with AI (50(1)), machine-readable marking of synthetic content by providers (50(2)), disclosure for emotion-recognition systems (50(3)), deployer disclosure of deepfakes and AI-generated public-interest text (50(4)), and clarity/timing rules for all disclosures (50(5)). The duties have applied since August 2, 2026.
Very likely yes if the ad reaches EU audiences. Article 50(4) requires deployers to disclose AI-generated or manipulated deepfakes, and Commission guidance extends the text limb to AI-generated advertising and PR on matters of public interest. The disclosure must be clear, distinguishable, and given at latest at first exposure (Art. 50(5)).
No. Disclosure is a user-facing notice a person can perceive; watermarking is a technical machine-readable marking of the file. Article 50(2) puts the machine-readable marking duty on providers, while Article 50(4) puts the visible disclosure duty on deployers — a deployer cannot satisfy their disclosure duty by relying on the provider's embedded mark.
Non-compliance with Article 50 by providers or deployers carries administrative fines of up to €15 million or 3% of total worldwide annual turnover for the preceding financial year, whichever is higher — imposed by national market surveillance authorities.
It can. Article 2 covers providers and deployers established outside the EU when the AI system's output is used in the Union — publishing to the globally accessible internet can be enough. A US company whose AI-generated content reaches European audiences should confirm its position with counsel rather than assume it is exempt.
