Will Amazon Reviews Become Mostly AI-Written?

Probably not in the near term — but the mix may keep shifting, and exact prevalence is hard to measure.

A safer way to think about it is:

• Amazon has strong incentives to keep reviews trustworthy, so it will keep fighting obvious fake or mass-generated review spam.
• AI has lowered the cost and increased the volume of fake review generation, so the pressure to inject AI-written text into review ecosystems will keep growing.
• That does not necessarily mean Amazon reviews become mostly AI-written, because moderation, fraud detection, purchase verification, and reputation systems make it harder for low-quality spam to dominate for long.

So the most likely outcome is more AI-assisted review spam competing with more automated detection, not a simple takeover of the entire review section.

One nuance: Amazon also features official AI-generated summaries at the top of many product pages, but those are separate from customer reviews.

What to watch for:

• sudden clusters of highly polished reviews in a short window
• vague praise with little product-specific detail
• repeated phrasing across many reviews
• reviews that sound like marketing copy rather than firsthand use

One important caveat: the exact share of AI-written reviews is not publicly measurable, and it can change by category, product, and time. For anything important, check whether the review is marked as verified purchase, look for detailed negative reviews too, and compare across multiple sources before buying.
