I think copy.ai has it out for Khan Academy
"I want to start a company based around making great educational content on truly complex concepts like OAuth. Think Khan Academy but also feel like you're talking with an expert."
That would very likely get me a better result than feeding this AI 3 sentences and having it come up with comedy gold like this:
"OAuth is like having the Facebook app on your phone, but you are using the same password that you are using for everything else."
what I usually say to speakers is a rough title and 3-4 bullet points of what you want to cover as a start-I think why it's challenging is folks try to "sell" the talk from the get go, rather than refine the focus, then worry about selling it
