Supplement copy is where sellers most often get into trouble with platforms and regulators. This helper reviews your claims line by line and suggests careful wording.
Each line is marked as likely fine, needs care or high risk, with a one-sentence reason and a rewrite for anything flagged.
Rules differ by country and platform and change over time. Use the review as a first pass and get final sign-off from a regulatory professional.
Can it tell me a claim is legal?
No. It gives general guidance on wording. Only a qualified adviser in your market can confirm a claim.
Can it add studies to support my claims?
No. It never invents references. It lists the kind of evidence you should keep on file for claims you make.
