Should Businesses Disclose When a Product Review Was AI-Generated?

Yes — businesses should disclose when a product review is AI-generated, because presenting AI-written content as a genuine customer opinion is widely treated as a deceptive practice under consumer protection principles, and undisclosed fake or synthetic reviews carry real legal and reputational risk.

Key takeaways

Consumer protection regulators in multiple countries have specifically targeted fake and undisclosed AI-generated reviews as a deceptive practice.
The core issue is not AI use itself but presenting synthetic content as if it were a genuine customer's independent opinion.
AI can play a legitimate, disclosed role — such as helping summarize genuine customer feedback — without that use being deceptive.
Platforms hosting reviews, such as major e-commerce and app marketplaces, have their own policies against fake or fabricated reviews, separate from government regulation.
Businesses caught using undisclosed fake reviews risk regulatory penalties, platform removal, and significant reputational damage if exposed publicly.

Fabricated Reviews Are a Deception Problem, Not an AI Problem

Businesses should disclose when a product review was AI-generated, and in practice, the more accurate framing is that businesses generally should not present AI-generated text as a genuine customer’s independent review at all. The concern here isn’t really about AI as a technology — it’s the same problem regulators have addressed for years with fake reviews written by paid humans, employees, or bots: presenting something as an authentic, independent customer opinion when it isn’t misleads shoppers who reasonably rely on reviews to make purchasing decisions.

AI has simply made it cheaper and faster to generate large volumes of convincing-sounding fake reviews, which is why regulators and platforms have specifically sharpened their focus on this practice as generative AI tools have become widely available.

Why Regulators and Platforms Treat This Seriously

Consumer protection regulators in multiple countries have explicitly identified fake reviews — AI-generated or otherwise — as a deceptive practice, because shoppers use reviews as a proxy for real-world product experience that they can’t otherwise access before buying. When that signal is fabricated, it undermines the basic function reviews are supposed to serve and can materially affect a purchasing decision the customer wouldn’t have made with accurate information. This has led to enforcement actions and regulatory guidance treating undisclosed fake reviews as a form of deceptive advertising, independent of whether an AI tool was involved in producing them.

Major e-commerce marketplaces and app platforms have also built out their own detection systems and policies specifically targeting fake and manipulated reviews, since review authenticity affects the credibility of the entire platform, not just one seller. Businesses caught violating these policies can face review removal, listing penalties, or account suspension — consequences separate from and in addition to any government regulatory action.

There is a meaningful difference, though, between generating fabricated reviews and using AI in a supporting role around genuine customer feedback — for instance, helping a real customer articulate their own honest opinion, or using AI to summarize themes across genuine reviews for other shoppers. These uses don’t involve presenting synthetic content as if it were an independent customer’s voice, which is the core issue regulators and platforms are targeting.

What Responsible Practice Looks Like

A business that wants to use AI around its review process while staying on the right side of both regulation and platform policy might use AI to help genuine customers draft reviews more easily (with clear attribution that it remains the customer’s actual opinion), or use AI internally to detect and filter out fake reviews from bad actors — but would avoid generating reviews wholesale and posting them as if written by real customers who never used the product. The distinguishing question is always whether a reasonable shopper reading the review would be misled about its origin and authenticity.

Given how seriously both regulators and platforms have started treating fake review practices, and the reputational damage that follows when a business is publicly caught using them, disclosure and authenticity aren’t just a legal safety net — they’re increasingly a baseline expectation for maintaining customer trust.

Bottom Line

Businesses should not present AI-generated content as a genuine, independent customer review, and where AI is involved in the review process at all, transparency is the safer and increasingly expected practice, given that fake reviews — AI-generated or not — are treated as a deceptive practice by regulators and a policy violation by most major platforms.

Important caveats

Specific disclosure requirements and enforcement approaches vary by country and by platform, so businesses should check rules relevant to where they operate and sell.
Using AI to help a real customer write or organize their own genuine review is a different situation from generating a fabricated review outright, though the distinction should be handled carefully and transparently.

Frequently asked questions

Is it ever acceptable to use AI in the review process without disclosure?

Using AI behind the scenes for legitimate purposes — like helping detect fake reviews, summarizing genuine review sentiment, or assisting a real customer in writing their own honest feedback — is generally viewed differently from generating fabricated reviews meant to look like independent customer opinions, though transparency is still the safer practice.

Can a business get in legal trouble for posting AI-generated fake reviews?

Yes — regulators in a number of jurisdictions have taken enforcement action against fake review practices, including AI-generated ones, treating them as deceptive advertising, and businesses can face fines or other penalties depending on the jurisdiction and severity.

Do major review and marketplace platforms detect AI-generated fake reviews?

Many platforms have invested in detection systems and policies specifically targeting fake and manipulated reviews, and businesses found violating these policies risk having reviews removed, listings penalized, or accounts suspended, independent of any government regulatory action.
