I've wanted to build something similar but mainly as a tool to help me aggregate and run a newsletter, then repurpose the content into tweets, auto generated short and long form videos, and Instagram posts. Say it pulls in news and maybe top new products for the day or week or past two days depending on frequency of newsletter, I run an ai newsletter https://curl.beehiiv.com https://curl.beehiiv.com, and am looking for ways to automate 90 percent and then the rest is just editing voice and tone and fact checking.
