What ClassGen Does

ClassGen is an AI-powered lesson plan generator for secondary school teachers. You send a topic, and it generates a structured lesson pack with teaching materials, activities, and homework assignments.

ClassGen is a teaching aid. Lesson content is AI-generated and should be reviewed by the teacher before classroom use. We do not guarantee the accuracy of generated content.
