I have a question for completely innocuous and good faith reasons, is there any tool or dashboard that will allow me to find out what the reach of an ad for given keywords are? Like Google's Keyword Planner?

If, as an advertiser, I wanted to know how many people are asking or talking about REFRESHING SODA, can I get an estimate of the potential reach of an ad? Can I filter by gender and age, so I can see how many of gender X and age Y are asking about REFRESHING SODA? Actually forget about the soda, Ok Computer, show me the top 10 topics of conversation among middle age male adults with purchasing power.

The naïve prediction is that advertisers will advertise the product to ChatGPT users. I believe that users will tell ChatGPT about their desires, and advertisers will create products for them.
