GUIDE is an offline learning platform specifically designed for teachers and choir directors, particularly those in third-world countries where internet access is limited. Delivered via flash drives, this platform includes features such as user login, progress tracking, and content updates, and is available in multiple languages to cater to diverse user groups.

GUIDE is centered around the Wirth method, developed by Professor Gerald Wirth. It aims to provide an in-depth understanding and mastery of this teaching approach. Through five comprehensive modules, users will be introduced to the tools and characteristics of the Wirth method by observing students in real teaching situations. These modules include live recordings from three cameras, capturing simultaneous views of the teacher and students during teaching, training, and assessment scenarios.
