Every ad you launch is a bet. You spend $500, wait a week, and only then learn your audience scrolled past, with no idea why.
FirstReaction runs that test before you spend. Describe your buyer and add your Facebook or Instagram ad. AI simulates how each audience segment reacts: predicted engagement and CTR, who scrolls past and why, fixes ranked by impact, and a Meta policy check.
Apply the fixes, create a V2 in one click, and test again.
