Use Lebesgue with Adrails: from ad audit to approved changes
Lebesgue is an analytics tool for ecommerce with automated ad audits, an AI assistant that answers why a metric moved, LTV analysis and first-party attribution. It recommends. Adrails prepares the matching Meta changes and applies them only after approval.

Step by step
Without Adrails, and with it
What Lebesgue already does stays as it is. What changes is everything after it.
| Step | Lebesgue alone | Lebesgue +Adrails |
|---|---|---|
| Know what works | Automated ad audits, an AI assistant and LTV cohorts. | Unchanged. Lebesgue stays the analysis tool. |
| Turn it into a change | Open Ads Manager and find each campaign, ad set and ad. | Tell the Media Buyer agent. It finds the entities in your account. |
| Check the change | Your own judgment, in the moment. | Current value, new value and reason shown side by side. |
| Apply it | Each edit is live as soon as it is saved. | Applied only after approval, change by change. |
| Keep a record | Meta's activity history shows what changed, not why. | Each change is kept with its reason, its reviewer and its before and after. |
01
What Lebesgue answers, and where it stops
Lebesgue audits Meta, Google and TikTok accounts automatically, answers questions such as why Meta ROAS dropped last week, and benchmarks you against other ecommerce brands. Le Pixel adds first-party attribution with the Conversions API.
Its assistant pages show analysis and recommendations. One plan lists AI bid management, which we could not find documented, so check that plan before relying on it for changes.
02
A recommendation is not yet a change
When Lebesgue says to move budget away from a fatigued ad, the Media Buyer agent in Adrails turns it into concrete proposals on the right entities, with the current and new values.
Nothing is applied until you approve, and every applied change is kept with its reason, so the next audit can check whether the change worked.

FAQ
Common questions
Does Adrails integrate with Lebesgue?
Not today. You bring Lebesgue's recommendation into the conversation, and Adrails prepares the change for approval.
Can Adrails change my budgets or pause ads on its own?
No. The Media Buyer agent proposes pauses, budget changes and scale decisions with the evidence behind them. Each one is applied only after a person approves it.
