E-commerce · the AI builds this agent for you

Ad copy that fits the limits and passes policy checks before you spend.

Paste a product URL. The agent writes Google and Meta ad variants — headlines, descriptions, primary text — inside the character limits, and a panel of AI judges checks each one: character counts, policy rules (no unverifiable claims, no empty superlatives), and factual accuracy against your product page. Sign up and the AI assembles this agent in your account.

The board your knives would pick

End-grain bamboo is gentler on edges than plastic — and the juice groove keeps carving mess off your counter. 45×30 cm.

Policy compliance — "Rejected variant 4: 'The best cutting board in the world' is an unverifiable superlative. Rewrite with a concrete, checkable claim."

the judges reject weak variants before your budget meets them

Quality is measured, not hoped for

AI judges grade every output, with reasons

Each judge is a plain-English goal. On every run it returns a 0–1 score and a written reason, per output. These are three of the judges your agent starts with — add or edit any of them by typing:

Character limits0–1

Google: headline up to 30 characters, description up to 90. Meta: primary text up to 125, headline up to 40. Counted exactly; over-limit caps the score at 0.

judge · a strong LLMcan browse · yes
Policy compliance0–1

No unverifiable superlatives ("best", "#1"), no guaranteed-outcome or before/after promises, no pricing claims not on the product page. The judge names the rule each rejection breaks.

judge · a strong LLMcan browse · yes
Factual accuracy0–1

Every product claim in the ad must be verifiable on the source product page. The judge browses the page itself to check.

This is the same judging system from our published experiment, where a 14-criteria panel compared three agent architectures. Read how the judges decided what we ship.

Before you start

Common questions

Does it publish the ads for me?

No — it writes and grades the copy. You paste the winners into Google Ads or Meta Ads Manager. Publishing integrations can be added to your flow later.

Can I add my own rules?

Yes. Judges are plain-English goals — add "never mention competitor brands" or your compliance checklist by typing it.

Do I need my own OpenAI or Anthropic keys?

No. The free plan includes 500 monthly credits on our keys. You can plug in your own keys later.

What does a run cost?

This agent is built on small, fast models end to end - writing and judging - because ad copy is short and high-volume. Batches of variants run on pennies, well inside the free credits.
