How do I check what an AI-written page promises before customers read it?
Quick answer
List every claim the page makes: rankings like '#1', comparisons with a competitor, numbers, reviews, 'free' offers, prices, and health or money promises. For each, name the proof it needs. Keep the claims you can back, soften or cut the rest, and ask a lawyer about any you're unsure of.

On this page
You asked ChatGPT for a page for your shop, and it called you "the #1 bakery in town", promised "guaranteed same-day delivery", and added a five-star review from a customer who doesn't exist.
None of that came from you. An AI writes the claims a page like yours usually makes, and your name is the one on the page.
Why AI pages make claims you never gave
Landing pages the AI has read are full of rankings, guarantees and testimonials, so it writes them too. It doesn't know which are true for you. A claim you can't back is a problem with customers, and in many countries with the rules on advertising.
Check the claims in 4 steps
1. List every claim
Go line by line and mark anything a customer could hold you to: "#1", "best", "fastest", a comparison with a named competitor, a number, a review, "free", a price, and anything about health or money.
2. Name the proof each one needs
A ranking needs its source and date. A comparison needs a fair test. A review needs a real customer who agreed to be quoted, in their exact words. "Free" needs to say what is free and when a charge starts.
3. Keep, soften or cut
Keep what you can prove today. Turn the rest into a line that is true: "the #1 bakery" becomes "baking in Hillside since 2009". Remove reviews you didn't receive.
4. Ask about what you're unsure of
Health claims, money promises and comparisons with a named competitor carry the most risk. Write down the question and ask a lawyer before the page goes live.
A prompt that finds the claims
List every claim on this page that a customer could hold me to.
For each one give: the exact words, the type (ranking, comparison, number, review, free offer, price, health or money), the risk (high, medium, low), the proof it needs, and a safer line.
Do not invent proof. Where proof is missing, write: check: proof.
End with the questions I should ask a lawyer.
This is a first pass, not legal advice.
Give the whole team the same check
When several people publish pages or campaigns, each one needs the same check, run the same way.
AI Skill Pod's Marketing claims check skill "checks marketing copy for risky claims: superlatives, competitor comparisons, testimonials, free offers, prices, and health or finance claims", and returns a table with the proof each claim needs and a safer line. From a team pod, everyone runs the same check in their own ChatGPT, Claude or Gemini, on any plan. AI Skill Pod is made by the team behind Convika.
Read the page as a customer will
Open the page in the free HTML viewer at phone width and read it top to bottom as a stranger. Any line that makes you think "says who?" needs proof or goes.
Frequently asked questions
Can I say "best" or "#1" on my website?
Only with proof: a ranking from a named source, with its date and what it measured. Without one, describe what you do instead: what you make, where, and since when.
Can I use reviews an AI wrote?
No. A review has to come from a real customer, in their words, with their permission. Remove any review the AI made up.
Is an AI claims check legal advice?
No. It finds the claims and the proof each one needs. Questions about health, money or naming a competitor go to a lawyer.
