The emergence of Generative artificial intelligence (AI) is rapidly transforming the digital ecosystems in which radicalization may occur easily. Earlier, search engines recommended limited information, mostly based on specific queries. AI has empowered human-machine interaction in a more personalized, continuous and adaptive way. This article examines the relationship between Generative AI, autonomous radicalization and lone-actor terrorism by integrating established theories, including Moghaddam’s Staircase to Terrorism, Bandura’s Social Learning Theory, and Kruglanski’s 3N Model and proposes an Interactive Radicalization Interface (IRI). This model of radicalization provide a framework to understand grievances, AI-mediated interaction, narrative construction, reinforcement and ideological progression. The study argues that AI operate as a force multiplier of vulnerability but does not cause radicalization or terrorism. The transition from passive exposure to interactive reinforcement without AI governance has raised concerns for prevention and Counterterrorism strategies.
