The workshop will introduce Luduan.ai, an AI-powered adaptive platform designed to enhance language learning and teaching. We will use Spanish and Portuguese as examples to showcase how generative AI can support the development of the four proficiency subskills  in a given language (e.g., reading, writing, speaking, and listening). The platform offers both teacher and student modes, allowing instructors to adapt lessons to individual learning needs. In addition to skill-building, we will discuss how Luduan.ai's accessibility features ensure inclusive learning environments for all students. The workshop will conclude with an interactive Q&A, giving participants the chance to dive deeper into AI optimization in the teaching of Spanish and Portuguese.
