AI testimonials and the FTC's review rule: where the line is
AI can make a convincing customer in seconds. The FTC's rule on reviews and testimonials says that customer has to exist, and has to have used the product.
Key points
The FTC's Trade Regulation Rule on the Use of Consumer Reviews and Testimonials, in force since October 2024, prohibits reviews and testimonials that misrepresent that they come from someone who does not exist or who did not actually use the product, and it names AI-generated fake reviews explicitly.
An AI avatar presented as a real customer saying "this cleared my skin" sits squarely in that territory. An AI presenter that is clearly a spokesperson, not a customer, and makes only claims you can substantiate, is a different case.
What the rule covers
The rule bars businesses from creating, buying or disseminating fake reviews and testimonials, including ones that claim to be by people who do not exist or who had no real experience with the product. It also covers incentives tied to positive sentiment, undisclosed insider reviews, review suppression and fake social-media indicators.
Unlike general deception cases, the rule lets the FTC seek civil penalties per violation. In December 2025 the agency sent its first public warning letters under the rule to ten companies.
Where AI ads cross the line
The risk is not AI itself. It is presenting AI output as a real person's experience. Watch for: an AI face with a first-person result ("I lost 8 kg"), a cloned voice reading a customer quote, star ratings or review counts generated for the ad, and UGC-style videos that imply an independent customer when the creator is paid or synthetic.
How to use AI presenters safely
Make the role obvious: a presenter or brand voice, not a customer. Keep claims to what you can prove. If you quote a real customer, keep the consent and the original words, and disclose any payment or free product under the FTC's endorsement guides. In the EU, add a visible AI label to realistic synthetic people.

Questions
Can I use an AI avatar in an ad at all?
Yes, as a presenter. The problem starts when the avatar is presented as a real customer or makes experience claims nobody actually had.
Do UGC creators need to disclose payment?
Under the FTC's endorsement guides, a material connection such as payment or free product must be clearly disclosed.
