Juanito es un asistente de inteligencia artificial para conversar sobre la fe católica. Responde con el Catecismo de la Iglesia Católica, el acontecimiento guadalupano y la doctrina social de la Iglesia, y cita sus fuentes para que puedas leerlas. Qué puedes hacer • Empezar por un tema: Catecismo, Guadalupe, doctrina social o teología del cuerpo, con preguntas para arrancar. • Preguntar lo que quieras sobre la fe: doctrina, sacramentos, moral, vida de oración, familia, trabajo o situaciones de la vida vistas desde el Evangelio. • Leer las fuentes: cada respuesta doctrinal cita el Catecismo con su número (por ejemplo, CIC 1511). Toca la cita y abre el párrafo sin salir de la app, o ve al texto oficial en vatican.va. • Conocer el acontecimiento guadalupano: las apariciones, el Nican Mopohua, Juan Diego y cómo vivir hoy el mensaje de la Virgen de Guadalupe. • Profundizar en el magisterio: la Teología del cuerpo de san Juan Pablo II y la encíclica Magnifica Humanitas de León XIV sobre la inteligencia artificial. • Dictar tu pregunta con el micrófono, adjuntar un documento a la conversación y compartir un chat por correo. • Usarla sin cuenta, como invitado, o con tu cuenta para guardar tus conversaciones. Cómo responde Juanito Juanito es una herramienta de inteligencia artificial, no una persona, y lo dice con claridad. No sustituye la dirección espiritual ni el acompañamiento de un sacerdote: en esos temas te orienta hacia personas preparadas. Sus respuestas pueden tener errores; por eso siempre muestra de dónde salen. Quién está detrás juanito.ai fue creado por la Misión MásAlto de los Legionarios de Cristo, dentro del Camino de Guadalupe, para formar agentes de pastoral y apóstoles de la nueva evangelización: los Juan Diegos de nuestros tiempos. Quiere ser una herramienta al servicio de toda la Iglesia, especialmente en la aplicación del Proyecto Global de Pastoral 2031-2033. También responde en inglés.
