Efficient household inventory management plays a relevant role in reducing waste and fostering sustainable consumption practices. This study presents AIGO, an application designed to support shopping planning and household supply control, aiming to minimize excess and promote more conscious consumption. The research was conducted in an urban Indigenous community and involved eight families who used the application over a two-month period. A qualitative approach was adopted to analyze the impacts of AIGO on consumption habits and household inventory organization. The results indicate that the tool contributed to waste reduction, shopping optimization, and increased user awareness of sustainable practices.
