Well done on the launch:

A lot of these GPT powered thing sites look the same. Same old “flat people” stock images etc. Maybe get a human graphic artist to spice it up.

Best way to demo is take me to a chat prompt trained on something (for example all pro basketball players) with no login and example prompts.

A show off of how you set it up is less important for first impressions. But it should be easy to set up (looks like it is)
