It analyses how AI is used by economic operators to influence consumer behaviour through personalised marketing strategies and automated contract formation, frequently intensifying unfair commercial practices. This development challenges the traditional foundations of consumer law, particularly with regard to the protection of contractual intent and the fulfilment of duties of communication and information.<\/p>\n\n\n\n<p style=\"font-size:16px\">The analysis further addresses the legal implications of contracting through autonomous artificial intelligence systems, questioning the applicability of conventional legal frameworks to non-human declarations of intent. It also examines civil liability for damages arising from the use of AI, highlighting the growing need for regulatory reform to ensure contractual transparency, integrity in commercial practices, and effective consumer protection. The discussion is grounded in national and European legislation, with particular emphasis on recent regulatory developments concerning artificial intelligence and defective product liability, as well as a critical review of relevant doctrinal contributions.<\/p>\n\n\n\n<p style=\"font-size:16px\"><strong>Keywords<\/strong><\/p>\n\n\n\n<p style=\"font-size:16px\">Artificial Intelligence, Unfair commercial practices, Adhesion contracts, Civil liability.<\/p>\n\n\n\n<p style=\"font-size:16px\"><strong>References<\/strong><\/p>\n\n\n\nBeck, U.
