Chatbot for a fitness website

I have an idea and looking for pointers on how to start. I want to use the playground to build a chatbot for my website. It’s a fitness website so the user can prompt for a specific type of exercise or activities on the website.
Any insight on how to start will help.

Are you looking for a prompt design? Or integrating your existing content?

Yes, a simple prompt design using speech and text.
An example would be
‘Fit, show me Yoga videos’

If name of chatbot is Fit.

Thanks for asking
