What You Can Legally Claim About AI in Marketing

Key takeaways

The FTC's own four questions live in a February 2023 staff post, "Keep your AI claims in check." It's free, it's short, and it's still the clearest thing the agency has written for solo operators.
In the FTC's own words, merely using an AI tool in the development process is not the same as a product having AI in it. That single line is what disqualifies most "AI-powered" headlines.
There's no general FTC duty to label marketing copy as AI-written. Authorship starts to matter when the words are attributed to a person, when a face or voice is synthetic, or when a platform's own terms require disclosure.
On December 22, 2025, the FTC reopened and set aside the Rytr order on a 2-0 vote, saying the complaint failed the FTC Act's legal requirements and unduly burdened AI innovation. That narrowed liability for tool vendors, nothing more.
The Rule on Consumer Reviews and Testimonials (16 CFR Part 465) took effect October 21, 2024 and is a legislative rule with civil penalty authority. The Endorsement Guides (16 CFR Part 255) are interpretive guidance, not a rule you get fined under.
Penalty exposure runs up to $53,088 per violation under 16 CFR 1.98(d), per 90 FR 5581 dated January 17, 2025. Because it's per violation, faked reviews at scale multiply the exposure.
DoNotPay's "world's first robot lawyer" claim was never tested against an actual lawyer. The January 2025 final order required monetary relief, notices to past subscribers, and proof before repeating the claim.

Questions people ask

Can I honestly say my service is "AI-powered"?

Only if your product actually uses AI in the way a customer would reasonably assume from those words. The FTC has stated that merely using an AI tool in the development process is not the same as a product having AI in it. If AI just helped you build the thing, say that instead. It's true, it's differentiating, and it doesn't overpromise.

Do I have to disclose that AI wrote my emails or blog posts?

Nothing in the FTC materials covered here creates a general duty to label marketing copy as AI-written. The rules govern misrepresentation, not authorship. Disclosure starts to matter when the words are attributed to a person (a testimonial, an endorsement, a quoted expert), when a face or voice is synthetic, or when a platform's own terms require an AI label. Those platform terms are contract obligations, and they'll cost you an account long before a regulator calls. This isn't legal advice, and state or industry rules can add requirements.

Is it illegal to use AI to write my testimonials?

The rule turns on misrepresentation, not on the tool. Inventing a testimonial from someone who doesn't exist, or attributing one to a real person who never used your product, is squarely prohibited under 16 CFR Part 465. Using AI to fix the grammar of a real client's real, approved words is not what that rule describes. The risk is the middle, where polishing quietly becomes inventing details the client never actually said.

Did the Rytr decision make AI marketing claims legal now?

No. On December 22, 2025 the FTC set aside its order against Rytr on a 2-0 vote, saying the complaint failed to meet the legal requirements of the FTC Act and unduly burdened AI innovation. But what was narrowed was liability for a tool vendor whose product could be misused by someone else. It does not legalize publishing a fake or invented testimonial, which remains prohibited.

What's the penalty if I get an AI claim wrong?

Penalty exposure runs up to $53,088 per violation under 16 CFR 1.98(d), per the Federal Register (90 FR 5581, January 17, 2025). Because it's per violation, a batch of fake reviews multiplies fast. This isn't legal advice, so confirm specifics with your own attorney.

Do the FTC's Endorsement Guides apply to AI?

The Endorsement Guides (16 CFR Part 255) are interpretive guidance on how the FTC reads the law, not a standalone regulation you get fined under, and they were written before generative AI became a marketing concern. The document with teeth is the Rule on the Use of Consumer Reviews and Testimonials (16 CFR Part 465), effective October 21, 2024. The FTC's September 2024 Operation AI Comply sweep went directly at AI-enabled fake reviews, with Rytr among the named targets.

Can I claim my AI works better than a human professional?

You can, but only with adequate proof you could show a skeptic. That's the exact trap DoNotPay fell into by marketing a "robot lawyer" it never tested against an actual lawyer, with no attorneys retained to check the quality of its law-related features. Comparing your AI to a trained human is legal. Making that comparison with no evidence behind it is the risk.
