marketing agents are about to get F*CKING stupid Meta's new AI app Muse hit #1 on the US App Store just 1 week after releasing and its already showing where this is going : agents that can actually take actions across apps instead of just giving you answers right now I can already see a setup where : -> one agent watches your competitors all day and saves the posts doing numbers -> another builds a Pinterest photo bank around those formats -> the images + hooks get fed into an LLM that turns them into new slideshow concepts and spits out the next batch ready to post same thing for UGC too. pull winning videos > break down what keeps repeating > write new hooks > generate variants > feed the winners back into the system you’d still need taste because agents will happily produce 100 pieces of dogshit if you let them. but a founder being able to run research → creative → production → posting → analytics with a few agents is where this gets crazy. Meta’s Muse feels like a pretty good preview of that world
