An AI media buyer for Meta ads that runs every morning. Watches your account, scrapes competitors, drafts creative briefs. Built from years of running ads inside Meta’s ads division.
Why I Built This
I spent several years working in the advertising division at Meta. I sat next to some of the best media buyers in the world, the people running 8 and 9-figure accounts every day.
What they all had in common wasn’t a magic touch. It was an obsession with the data. Pulling the right reports. Spotting the patterns. Understanding why things were working, not just that they were.
That’s the brutal part of media buying. Analytics-driven decisions at scale are nearly impossible for one human to keep up with. By the time you finish auditing one campaign, four others have shifted. You scale the wrong winners. You kill the wrong losers. You don’t notice creative fatigue until your numbers are already broken.
So I took everything I learned from those buyers (the kill rules, the scale criteria, the audit frameworks, the creative analysis) and packaged it into an AI agent. Tested against my own ad accounts, across my own brands, every edge case I could throw at it.
What This Took to Build
It took me weeks of building
and thousands of dollars in API tokens
to make this happen.
Not a template. Not a prompt wrapper. The actual production system I run on my own businesses, built from years inside the best ad-buying environment in the world.
Daily
Morning account scan
Pulls every Meta metric that matters: spend, ROAS, CPA, CPP, frequency, CTR, CPM. Across every campaign, ad set, and ad. Flags ads that crossed kill thresholds (like 2× CPA with zero purchases). Identifies winners ready to move from testing into scale. One structured brief every morning: account scorecard, trend summary, ranked action list, creative priorities. Two minutes to read.
Weekly
Full intelligence loop
A deeper review every week: full account audit, scorecard against your benchmarks, 7-day and 30-day trend analysis, creative fatigue check on every running ad, and a strategic brief for the week ahead. The work an agency was supposed to be doing.
Market
Competitor + expert research
Scrapes competitor ad libraries to identify the formats, hooks, offers, and visual patterns other brands are scaling. Tracks Meta-ads experts on X so you never miss an Andromeda update, an Advantage+ shift, or a new tactic worth testing. Combines what’s winning in YOUR account with what’s working across the market.
Creative
Visual analysis + production briefs
Analyzes the visuals of your top and bottom performers: format, product prominence, color, contrast, composition, hook style, copy structure, CTA. Detects fatigue signals before performance drops. Synthesizes account data + market signals + customer voice into briefs your team can shoot from. Specific hooks, specific angles, specific test hypotheses. Not “make some new content.”
Safety
Read-only by default
It cannot spend a dollar without you. Read-only is the default. Even with write access enabled, every campaign, ad set, and ad it creates ships in paused state. You flip the switch in Ads Manager when you’re ready. No automatic budget increases. Ever.
