Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers.

Lexie takes 46 steps of AI prompting, context explanation, and output formatting and makes it one step: point camera, get quiz. The photo constraint isn't just better UX, it's the only way to get usable output from that age group. This demographic gets the worst deal in edtech. Too advanced for baby apps, too young for adult tools. They get gamification theater instead of real learning tools. I stripped all that out. Photo your geology notes, get instant…
