Free tools

Two numbers worth checking before you touch a budget.

No signup, no email, no account connection. Both tools run in your browser, print the formula they use, and name the source of every figure they quote — so you can check the answer instead of taking it.

The rules we built them under

A tool that asks for your data before it answers isn’t free.

Nothing is collected

No signup, no email for the result, no OAuth. The maths happens in your browser and neither page makes a network request while you use it — so there is nothing for us to store.

The formula is on the page

Each tool prints the arithmetic it runs and the assumptions it makes. If you disagree with an assumption you can see exactly which one, and redo it by hand.

Every number has a source

Platform thresholds are quoted from Meta’s and Google’s own documentation and linked. Where a figure is directional, it says so instead of dressing an estimate up as data.

These are deliberately narrow. Neither tool reads an ad account, so neither can tell you what is actually leaking in yours — that needs read access, and it is what the free audit does. What a browser tool can do honestly is give you the floor to judge against: the ROAS you have to beat, and whether there is enough data behind the number you are reading. The rest of the reasoning lives in the product: ground truth for what the platforms report against what your analytics recorded, the Trust Gate for the too-little-data side.

Frequently asked

The free tools, answered.

Do I need an Adgent account to use these?

No. There is no signup, no email wall and no ad-account connection. Both tools compute in your browser, and neither page makes a network request while you use it, so we never see the numbers you type.

Why is the arithmetic printed on the page?

Because a number you cannot check is not much use. Each tool states the formula it runs, the assumptions behind it, and the source of any figure it quotes, so you can reproduce the result on paper without trusting us.

What do these tools not do?

They do not read your ad accounts. Nothing here can tell you whether your conversion tracking is intact, which campaign is leaking budget, or what changed overnight. That needs read access to the accounts, which is what the free audit is for.

What gets added next?

Only checks we can compute honestly from numbers you already have. Anything that needs your account data belongs in the product behind an approval, not in a browser tool, and we would rather ship two calculators we can stand behind than a wall of generators.

Free account audit

The tools give you the floor. The audit gives you your numbers.

Send us the accounts and we will run the read Adgent would run — read-only, on your live Meta and Google data — and show you where the money is going that the dashboard is not flagging.

Read-only — nothing is changed
Reads GA4 and Search Console for context
Tells you what it can’t answer yet, and why

What comes back

The brief Adgent would write on day one, the leaks it found and what they are worth — and, where the data cannot carry a verdict, what it will not call yet and why.

Thanks — we’ve got it.

We’ll be in touch within a couple of working days.
