A.I. for content creation

I’m curious if anyone has used A.I. to create a content strategy for social media and email ongoing outreach. I’d like to create a calendar that will become a “post this today” on a calendar so I have an exact playbook daily. One of my goals this year is to do a better job of keeping in touch with the people that already know/like/trust me by sharing educational content. I’ve played around with some of the custom GPT’s such as the Liability Advice Engine and the Borrow Smart Story brand and both seem to do a fairly good job. There’s SO much amazing content from this community and my goal is to build a quarterly content calendar by uploading .pdf’s and web links to some of the content to create content that adds value and of course use the Lendsight A.I. platform per our kick off call. Have any of you used any other LLM’s to build out a content creation strategy? If so, any insight would be greatly appreciated!
