This methodological study involved content and appearance validation conducted by ten healthcare professionals and seven Information and Communication Technology (ICT) specialists, respectively. The study followed the recommendations of the Standards for Quality Improvement Reporting Excellence (SQUIRE 2.0) and the principles of the Object-Oriented Hypermedia Design Method (OHDM), encompassing the phases of textual corpus development (modeling), design of the chatbot’s structure and operation (navigational design and abstract interface), and implementation, including validation procedures and usability testing. The ChatLinoHans chatbot achieved satisfactory results across all validation assessments. Expert evaluation yielded a Content Validity Index (CVI) of 0.98, ensuring the credibility and legitimacy of the chatbot. Appearance validation performed by technical judges resulted in agreement rates ranging from 85.7% to 100%, confirming its adequacy in terms of appearance. Usability testing scores ranged from 77.5 to 100, indicating above-average performance.</p>
