I'm on a flight with no wifi. Can you still help me outline the pitch?
Yes. I run locally on this laptop and do not require a network connection after setup. What would you like help drafting?
Okay: the model can run locally.
Good spine. Open with the claim, prove it with a demo instead of a chart, and close on what it makes possible. Want me to draft the opening thirty seconds?
