Doesn't work for the German client and doesn't say that on the tin which wastes a lot of time.

First, it's odd how all of the reviews for this extension seem fake themselves, for some reason. Second, it's really not clear how this works. When I collect reviews, the button in the lower right corner says "Collect Reviews (10)" and "Analyze Reviews (10)" no matter how many reviews there are. When I paste the URL directly into nullfake.com, it collects more reviews than that. I'm not sure what "(10)" means, really. Finally, the instructions say to go to "nullfake.com/API" to get an API key, but all I see is a 404 error on that page. In sum, I have no idea whether it's working or provides useful information.

If you shop based on reviews, this is a great add-on. Extracting reviews is effortless, and the AI analysis helped me avoid a purchase that looked “too perfect” on paper.

No bloat, no confusing setup. It quickly grabs the reviews from the product page and sends them to the service. The analysis report is straightforward and easy to understand.

I’ve been burned by questionable Amazon reviews before. This extension makes it simple to pull the reviews and get a second opinion. The fake/AI signals are genuinely useful.

Install → extract reviews → submit for AI analysis. That’s basically it. The results are clear and saved me time compared to manually reading hundreds of reviews.

Really easy to use. I exported the Amazon reviews with one click and sent them for analysis. The fake/AI review breakdown made it way easier to decide whether to trust the product page

a good idea, but not well executed. I collected 100 reviews, and yet the analysis says, we've analysed 5 reviews and concluded... 5 is hardly a good sample, and what's the point of me extracting reviews if you are not going to use them? 2 stars because it did analyse 5 reviews on the website, otherwise 1 start, as the extension seems to be pointless.

I checked the output against several products. I read through the reviews of the products as well and did additional online research. This extension (and website) appears to provide accurate feedback. I definitely recommend.

Great idea, sadly doesn't work just says "Analysis processing... waiting for completion" Also had the same issue when trying to use the browser potentially offline.
