Easy to train AI on these things if you're consistently using a few tools.
I have Pro AI tools trained on my brand(s)' voice & tone, style for each social media persona (founders, sellers, devs), and leverage GoogleLM Notebooks for things like competitive research, value props, persona psychographics, etc.
Out of box tools – I've only seen suites like TofuHQ or Flare.ai handle automation of content once you train it on your brand guidelines etc.
