This paper outlines the design, development, and preliminary usability study of a system comprising (1) a web-based Indigenous lesson-creation interface and (2) an accompanying mobile app for studying the lessons. The Nisotak project was developed in response to the need for the preservation of Indigenous languages and to support reconciliation within Canada. In this paper, the authors discuss the technological aspects of the project and the less tangible decision-making that helped navigate software development in ways that support and honour Indigenous languages, Indigenous knowledge, and Indigenous people while, at the same time, making space for non-Indigenous allies. The key decisions that guided this project included privileging the target language(s), accommodating multiple dialects, creating an easy-to-use and engaging interface for non-technical users, and designing for easy transfer of ownership and management. Finally, the authors share the results of a small usability study.
