The custom RAG system enhances accuracy for local questions, making the app a valuable digital companion in the tech ecosystem of the country.

If widely adopted, DomiChat has the potential to become the first mainstream AI assistant tailored for a Caribbean nation. It could bridge the digital literacy gap by offering natural language interactions in local dialects, making advanced technology accessible to broader demographics. Schools could integrate it as a learning aid, government offices as a support tool, and professionals as a smart assistant in their workflows. Over time, DomiChat could inspire similar region-specific AI solutions across Latin America, positioning the Dominican Republic as a pioneer in culturally relevant artificial intelligence.
