Hands-on: The "Persona" Test

Try to ask ChatGPT the same question using three different "personas":

1. "Write a short pitch for a new coffee shop as a Business Consultant."
2. "Write a short pitch for a new coffee shop as a Poet."

Observe how the "Industry" or "Persona" drastically changes the tone and content.
