You don't need custom built anything, ChatGPT could generate corporate initiatives and PR statements all day and no one would notice.
I still remember when I used ChatGPT the first time to write an email. I thought to myself “Oh. This sounds like 99% of the corporate communication from above”. We were joking that corporate had BossGPT for years and just didn’t tell anybody.
It also made me realize that most the so called “creatives” in marketing and PR also just repeat variations of the same few templates. Not much real creativity there.
The hallucinations would be a feature in this case.
100% been saying this for a while now. the main thing AI will be able to replace is a C suite.
