Can AI spot fake Amazon reviews?

Yes—AI can help spot fake Amazon reviews, but it is not perfect and it works as part of an ongoing cat-and-mouse game.

Amazon appears to use machine-learning systems to flag suspicious activity before reviews are published, based on signals such as account behavior, review patterns, and other data that Amazon does not fully disclose. Publicly discussed factors can include things like IP and login patterns, the relationship between sellers and reviewers, and how quickly reviews appear, but the exact system is not fully known from outside the company.

Third-party tools can also analyze public review text and patterns to estimate how trustworthy a product’s reviews look. However, those tools are not definitive. They can miss well-written synthetic reviews, and they can also wrongly flag legitimate ones. Generative AI has made fake reviews easier to produce at scale, which makes detection harder.

So the short answer is: yes, AI can spot many fake Amazon reviews, but it should be treated as a signal, not proof.
