The video introduces ChatGPT Canvas, a highly useful feature for teachers to create integrated learning materials. Unlike separate prompts, Canvas allows users to sequentially add and arrange various content types—like texts, vocabulary tables, comprehension questions, and even video links—onto a single document. This eliminates the need for copy-pasting and ensures all generated content is formatted and ready for print in one cohesive unit. The presenter demonstrates its application by building a language learning resource, highlighting its power and versatility for any educational context.
