I run paid ads with other people's money for a living. This is the AI kill switch I built so I can sleep at night, knowing I'll never waste a penny of their budget.
It's a setup you build once, inside your own Meta account, using Claude Code. It watches every ad, ad set and campaign as often as you like, and the second something breaks a rule you set, it pauses it. On its own. Even at 3am while you're asleep.
For just £27, I'll show you exactly how I build mine.
What it looks like when it catches one. This actually happened on a Tuesday.
Every media buyer knows the feeling.
You're running paid for clients. Real budgets, real money, going out every single day. And there's a low hum of dread that never quite switches off: what if one of them runs away overnight?
A creative fatigues. A CBO dumps the day's spend into one dud ad set. An audience tanks at 2am. By the time you've had your coffee and opened the account, it's already torched a few hundred quid of someone else's money. And it's your name on the report.
So you check. And check again. You refresh dashboards at the dinner table, glance at your phone in bed, half-watch accounts you can't physically watch every minute. It's a tax on your attention that never ends.
I got tired of being the alarm system. So I built one. It watches the accounts for me, around the clock, and kills anything that misbehaves before it does real damage.
What it actually does
You set the rules. It enforces them, tirelessly, on whatever schedule you choose. No guessing, no babysitting.
- ✓Watches at every level - ad, ad set and campaign. Nothing slips through.
- ✓Runs on your thresholds - CPA ceiling, spend with no conversions, ROAS floor, whatever you decide.
- ✓Checks as often as you want - every 15 minutes, hourly, daily. You set how tight the leash is.
- ✓Pauses automatically, or just messages you first - run it in alert-only mode until you trust it.
- ✓Never touches anything you didn't tell it to. No bid changes, no budget changes. It reads, and it pauses.
What you get for £27
Never used Claude Code in your life? Doesn't matter. You drop in one file and it guides you the rest of the way - from nothing installed to a live kill switch watching your account. No code, no video to pause and rewind. It asks, you answer, it builds.
The guided build
Drop one file into Claude Code and it walks you through the whole thing, step by step - including wiring up your Meta access. It asks what it needs, opens the right pages for you, and builds your kill switch with you. No video, no code.
My ready-to-use rule files
The exact files I drop in, written for you. Conservative and aggressive presets, across all three levels. Change the numbers to your accounts and you're done.
The one-page quickstart
Every step on a single page, for when you want to add another account or rebuild it next month - without running the full guide again.
That's it. No 14-module course you'll never finish. One sharp tool, running today.

Less than a takeaway, for something that protects every client budget you run, every day, forever. This is the early price while it's new - it goes up once the first hundred people have it.
30-day money back. Build it, and if it doesn't do exactly what I've said on this page, email me and I'll refund you in full. No hoops. The risk is mine.
Who this is really for
This is for people running paid traffic on other people's money - freelancers and agencies with live client budgets on the line every day, where one runaway ad is a real problem and your reputation is part of the bill.
It's not for you if you don't run paid ads, or if you want someone to run them for you. This teaches you to build the safety net yourself. It's a kill switch, not a strategy.
Questions
Do I need to be technical?+
No. You don't follow a video or write any code. A guide runs inside Claude Code and walks you through every step - you just answer its questions and click where it tells you.
Is it safe to let it pause my ads?+
It only ever does what you tell it to. You set every rule, and you can run it in alert-only mode first - so it just messages you when something breaks a rule - then let it start pausing once you trust it.
What platforms does it work with?+
It's built for Meta (Facebook and Instagram). The same method extends elsewhere, but the guide is Meta start to finish.
What do I actually need?+
Claude Code on a paid Anthropic plan - if you've never touched it, getting it set up takes about ten minutes. A free Cloudflare account - that's where your kill switch lives, so it keeps running even with your laptop shut. And admin or partner access to the Meta ad account you're protecting. That's the whole list.
How long does it take to set up?+
Most people are up and running in an afternoon, even starting from nothing installed.
I built this because I needed it myself, and it's saved me more than a few uncomfortable conversations with clients. If you run other people's ad budgets, you should have one too. Any trouble setting it up, email me directly and I'll help you get it running.
