In collaboration with Google Cloud, Walden University has created a new tool that uses artificial intelligence to help students review and master course concepts. The technology, which the institution is calling an AI-powered tutor named "Julian," taps into Google Cloud's AI and machine learning capabilities to generate a variety of on-demand learning activities. When an instructor loads course content into Julian and details the specific competencies — or "learning units" — required, the tool indexes the content and links each learning unit back to the related course content.
