The preservation of Indigenous languages is hindered by the scarcity of technological resources and the lack of culturally appropriate educational tools, a reality that is evident in the Kayapó (Mebêngôkre) language. This article presents the development of a bilingual digital platform aimed at language teaching, learning, and linguistic preservation, designed through bibliographic research and software engineering principles. The study combines the identification of sociocultural requirements, prototyping with emerging technologies, and comparative functional validation. The results indicate that the platform is feasible, accessible, and compatible with Kayapó language learning practices, contributing to community engagement and linguistic revitalization.
