Objective: To assess nursing students' perceptions of an artificial intelligencebased chatbot as a preparation tool for high-fidelity clinical simulations compared to traditional lectures. Methods: A crossover study was conducted with 40 third-year nursing students. Two preparation strategies were implemented: a chatbot for the first simulation and traditional reading for the second. Students' perceptions were then assessed using a validated questionnaire. Results: Students perceived the chatbot as a more interactive and efficient time management tool compared to traditional lectures. Additionally, they highlighted its usefulness in organizing information and enhancing their theoretical preparation for clinical simulations. Conclusions: The chatbot was perceived as an effective tool for clinical simulation preparation, facilitating study organization and improving the understanding of key concepts. Keywords: Education.
