The article explores the concept of artificial citizenship as a critical lens to understand how artificial intelligence (AI) is reshaping the conditions, rights, and practices of civic participation in the postdigital society. In a context marked by geopolitical instability, pandemic legacies, and deep mediatization, the traditional notion of citizenship is being redefined by platform logic, algorithmic governance, and the rise of generative AI. 'rough the analysis of theoretical perspectives (Floridi, Jandric, Selwyn, Calzada) and empirical examples – including deepfake politics, AI-generated disinformation on TikTok, and controversial interactions with conversational agents such as Replika – the paper highlights the epistemic, ethical, and pedagogical challenges posed by autonomous systems. The article argues that AI agents are not merely tools, but sociotechnical actors that affect knowledge production, communication patterns, and identity formation, thus complicating the democratic exercise of digital citizenship. It advocates for a renewed critical AI literacy as a civic competence, essential to address emerging risks such as cognitive delegation, opaque intermediation, and algorithmic exclusion. Ultimately, the article calls for a transdisciplinary educational project that empowers citizens to question, shape, and govern AI technologies in transparent and participatory ways.
