Sorry I can’t give this topic a like at present. 
Don’t take that to mean I don’t like what the AI is doing, I think that part is great.
The video started from a Draft and most users will start from New Topic so it was a bit confusing for me when I tried this on the OpenAI forum where this is active thinking it should work.
When I started with New Topic I had to enter the title, select a category, skipped adding tags and add two lines in the post before the magic AI options appeared.
Then after adding more text the AI buttons appeared.
I do find the post quite useful and you did a nice job, just needs some clarification for users not use to this technology.
