The AI Tutor Course Creator is where teachers build custom interactive lesson slides for the Irina AI tutor. These guides explain how to structure a slide, add practice problems with answer regions and scratchpad work, write Socratic hints that walk a student through a problem step by step, configure voice interactions for conversational concept checks, choose the right question type (write regions, multiple choice, drag-to-buckets, connect, label), and preview how each slide renders in the live tutor. Advanced articles cover the authoring pipeline that generates coordinates automatically from a source PPTX, how re-rendering and redo-slide work, and how the grader validates student responses against your correct answers. Start with the "create your first lesson" guide if you're new, or jump straight to the question-type reference if you already have content you want to import.
