This introduction sets the stage for the edited volume Coaching in the Age of AI by exploring the conceptual foundations and guiding questions that shape the book. It addresses the growing ambiguity surrounding both “coaching” and “artificial intelligence” (AI), proposing a framework to understand how these domains intersect in practice and theory. The chapter outlines three scenarios for how coaching and AI can be integrated: (1) AI as a means to enhance human coaching, (2) AI as a potential substitute for human coaches, and (3) AI as a tool for training and supervising coaches. These scenarios inform the book’s overall structure and thematic sections. In addition to mapping these perspectives, the introduction defines coaching as a professional developmental approach that emphasizes self-regulation, personal congruence, and goal-oriented learning. It highlights the relevance of coaching in an AI-driven world, where human judgment, ethical reflection, and adaptability are increasingly vital. Ultimately, this chapter provides a conceptual and ethical grounding for the book’s contributions and invites readers to engage critically with the evolving relationship between coaching and AI.
