AI Training for Authors

I’m a late adopter of AI tools (with the exception of dictation and ProWritingAid), but now realize that I need to catch the AI train before it’s too late.

Which courses are best to get up to speed on skills? Below are two sources I’ve been considering:

https://www.aiforauthors.net/ (The demo video looked pretty good. Already learned some key elements about prompts.)

#AI Writing Summit (Free) (The event is over, but it appears you can purchase recordings for $97?)

Has anyone received training from either of the above two sources, and would you recommend them? If not, which training courses for authors do you recommend?

Thank you, in advance, for your guidance and support!

P.S. I’m eager to start training this month.
