When is AI obvious? The exception applies only where almost no doubt remains

The Commission guidelines of 20 July 2026 place on the provider, in point (42), the burden of assessing and demonstrating the obvious artificial nature of the interaction to a person who is reasonably well-informed, observant and circumspect, taking into account the circumstances and the context of use. Point (43) anchors that standard in the notion of the 'average consumer' in EU consumer protection law. Point (44) prescribes a two-step assessment: first the provider considers the audience with whom the system is intended and reasonably likely to interact, then how well-informed, observant and circumspect an average member of that audience is. That same point states that the exposed audience does not always equal the target audience, that expected levels are lower where persons with disabilities, elderly people or minors are likely to be part of the audience, and that levels may be higher for an exclusively professional or specialised audience. Point (45) states that the exception should be interpreted restrictively because it deprives natural persons of the right to clear and distinguishable disclosure, that general awareness that AI systems exist does not imply that people recognise them in interactions, and that the exception should be limited to cases where there is almost no doubt left about the nature of the interaction. As examples where the exception does apply, the document lists among others code assistance chatbots available only to professional developers, an internal employee-facing assistant for properly trained and AI-literate staff, systems used only by properly trained health professionals, ambient AI embedded in home appliances, and non-playable characters in a single-player video game. As examples where the exception does not apply, the document lists a robotic companion pet closely resembling its natural equivalent, AI in immersive environments using realistic avatars or voices, and chatbots on online platforms or helpdesks whose outputs users may perceive as human-generated.

This is the most frequently over-claimed exception. The reasoning 'everyone knows this is a chatbot' is explicitly rejected by the guidelines: general awareness that AI exists is not the same as recognition in the actual conversation. What matters is not what your average customer knows, but who could reasonably end up at your system. As soon as your system is publicly accessible, the broader audience of elderly people, children and people with lower digital literacy is by definition included, and the exception falls away. The mirror image matters just as much and is often missed: for a strictly internal assistant used by trained staff, the Commission does expressly recognise the exception. Note the condition embedded in that example, namely that the staff are actually trained and AI-literate. That ties this exception directly to your Article 4 measures: without demonstrably AI-literate staff, the foundation for relying on the exception falls away.

Rely on this exception only for systems with a closed, professional user base, and record the two-step assessment in writing: who is the target audience, who else could reach it, and why almost no doubt remains for an average member of that audience. For anything publicly accessible, assume you must disclose. Link any internal reliance on the exception to your Article 4 file, so you can show that the staff concerned were genuinely prepared for the use of that system.
