As generative AI becomes embedded in higher education, many instructors struggle to prevent AI tools from replacing student learning. This session introduces a practical, instructor-controlled approach to designing custom AI teaching tools that prioritize guidance, feedback, and explanation instead of content generation. Participants will learn a step-by-step framework for building task-specific custom AI tools and explore adaptable examples that can be implemented across disciplines and course formats. Attendees will leave with concrete strategies they can apply immediately in their own teaching. (custom AI tools, instructor-designed AI tools, AI pedagogy)
