Day one of a two-day, all-day training at Hyosung Information Systems is wrapped. When I came last July for sales presentation training, I focused on domain knowledge and added only about two hours of AI on the last day, but the feedback was,
We got a lot of feedback saying, "John, please do more of that part on making slide decks with AI," so...
This year I flipped the order. We opened with how to use AI, then I ran the sales presentation slide prompt generator I built myself and demonstrated producing an actual slide deck with Genspark AI Slides and Claude Cowork. The response in the room was great, and then one participant came up with another idea. "John, you know those rough hand-drawn sketches from class? Is there a web app that turns them straight into infographics?" …If there isn’t, we build one.
Tonight at the hotel, I plan to build one with vibe coding. It would be even more fun to try it right in the training room tomorrow morning. Requests for my sessions keep evolving. It used to be, "Please explain this concept more," and now it is, "Please build us a tool that does this." I think that is a good sign. Sounds fun. Haha
