The EU AI Act's Article 50 transparency obligations took effect on August 2, 2026. The European Commission published its official compliance guidelines on July 29 — the most detailed implementation document available before the deadline. Key obligations for legal tech operators: (1) Providers must design AI systems that explicitly inform individuals when they are interacting with an AI system; (2) Providers must add machine-readable marks to AI-generated or AI-manipulated content; (3) Deployers must inform individuals when they are exposed to emotion recognition tools, biometric categorisation, deepfakes, or text published on matters of public interest without human review. Enforcement is by National Market Surveillance Authorities, the AI Office (for high-impact general-purpose AI), and the European Data Protection Supervisor. Penalties reach €15M or 3% of global annual turnover. For legal tech operators with EU customers, EU offices, or EU-market-facing products: Article 50 compliance is now operational. Every AI system that interacts with end users (chatbots, AI research assistants, AI drafting tools with user-facing interfaces) must have disclosure architecture in place. The transparency guidelines are the most actionable compliance document available — operators who have not mapped their products against the Article 50 obligations should do so this week.
