# The paid ads platform for developers and agents

Let your AI agent handle the ad work. It recovers the conversions Meta misses and acts within your limits.

[Start building for free](/register) · [Connect your agent to Meta Ads with MCP](https://plainrouter.com/docs/mcp/setup)

## Spending on ads is easy. Scaling profitably isn't.

Stop spending on losers and scale the winners, without living in Ads Manager.

| Before Plainrouter | After Plainrouter |
| --- | --- |
| You, in Meta Ads Manager | Agents and rules run Meta ads |
| Budget keeps flowing to losers | Losers paused, budgets cut |
| Ad blockers hide conversions | Recovers blocked conversions |
| Winners wait until you notice | Scaled with your approval |
| Agent access feels too risky | Approvals and a kill switch |
| No proof a change landed | What Meta confirmed, and when |
| Every change, by hand | Every change, on record |

## Everything it takes to scale profitably

See every conversion. Back the winners. Test new ads.

### Let your agent do the legwork.

It spots winners and losers before you would.

### Set the pace. Keep control.

Approve changes in Ask. Let Full run them on its own.

### Launch new ads.

Fight creative fatigue. Test [new creatives in bulk](/product/launch).

### Make changes from your own tools.

[No Ads Manager needed](/product/actions).

Your agent proposes changes. Ask waits for your approval; Full can pause ads and cut budgets automatically. [Actions checks and records the result](/product/actions), and changes that break your rules stay blocked in the Inbox.

### Recover more conversions.

Get back the ones your [Pixel never saw](/product/signals) and boost your ROAS.

### Cheaper conversions, same budget.

It all adds up to a lower cost per conversion.
