This is the best summary I could come up with:

The summaries have been in testing for at least a couple of months, and they’re now more widely available to a “subset” of users in the US on Amazon’s mobile app.

Amazon says they’re available “across a broad selection of products.” So far, we’ve seen them on TVs, headphones, tablets, and fitness trackers.

That said, that could be because Amazon’s search already elevates highly rated products, so it’s hard to find summaries of anything that people have been particularly frustrated by.

The feature can be found at the top of the review section on mobile under the heading “Customers say.” At the end, the paragraph includes a note that it was AI-generated.

Amazon says the summaries only pull from verified purchases in an effort to cut down on fake reviews.

As more platforms roll this out, the big question for users will be how much they can trust summaries from a service that’s clearly trying to sell them something.

I’m a bot and I’m open source!

Hmm my last review couldn’t be posted because I called them slave masters.

here a slightly more positive take on these 1 star reviews
