How this service works
Pay $2.00 USDC, get an FTC compliance lint report on your wellness or marketing copy. Flags unqualified efficacy claims, disease treatment claims, weight loss hype, and unscientific buzzwords.
Output
Returns a JSON object with an `ok` boolean and a `findings` array. Each finding includes the flagged term, a rule ID (e.g. FTC-FDA-APPROVED), the snippet of offending copy, a severity level (e.g. 'block'), a plain-English explanation of why it violates FTC guidelines, and a suggested rewrite to make the claim compliant.
Example use cases
Pre-launch supplement ad review
“Before we publish this landing page copy for our new collagen supplement, can you lint it for FTC compliance? I'm especially worried about the phrases 'reverses aging' and 'clinically proven to restore youthful skin' — tell me which ones are violations and give me safer rewrites.”
Email campaign compliance check
“We're sending a weight loss email blast tomorrow. Can you check this copy for FTC issues? It says things like 'melt away 30 pounds in 30 days' and 'scientifically formulated to eliminate belly fat' — flag anything that could get us in trouble.”
Wellness brand website audit
“Our wellness brand homepage says 'FDA approved detox tea that treats inflammation and boosts immunity' — can you run a compliance lint on that and tell me the severity of each violation plus how to rewrite the claims so they're FTC-safe?”
