Can AI detect fake Amazon reviews?

Yes—AI can help detect fake Amazon reviews, but it is not perfect.

Amazon uses automated systems, including machine learning, to look for suspicious review activity and may block or remove fake reviews before or after they are published. Third-party tools can also analyze reviews for signs of manipulation.

These systems typically look for things like repeated wording, unusual review timing, clusters of similar reviews, reviewer behavior, and other patterns that suggest inauthentic activity. In some cases, detection can also involve signals such as shared account or network behavior.

That said, this is an ongoing cat-and-mouse game: people can generate more natural-sounding fake reviews, and some fake reviews are written by real people rather than obvious bots. So AI can flag likely fakes, but it cannot reliably catch every fake review.
