Young urban migrants can be valuable actors in projects that aim to document and revitalize their Indigenous languages, especially when these efforts involve new technologies. Based on data from a Huastec (Tének) language documentation project in Mexico, this article describes the digital interactions of young migrants in the documentation and revitalization of Indigenous languages. To address this issue, we briefly review the migration of Huastec speakers in the context of language shift. We then examine how digital language activism can be linked to language documentation and explore how such digital projects can contribute to language maintenance and revitalization. Finally, we present the most salient factors that drive Indigenous migrants to participate in initiatives aimed at language revitalization through digital language activism: entertainment, affection, and being connected.
