How to Use Null Fake - Amazon Review Analyzer

Step 1: Install the extension from the Chrome Web Store. After installation, click the extension icon in your browser toolbar and go to Settings. Enter your API key from nullfake.com and save it.

Step 2: Go to Amazon.com (or any Amazon website) and find a product you want to check. You'll see a small button appear in the bottom-right corner of your screen that says "Extract Reviews".

Step 3: Click the "Extract Reviews" button. Amazon will take you to the reviews page and the extension will automatically collect the first 10 reviews. You'll see the number on the button update to show how many reviews have been collected.

Step 4: Scroll down to the bottom of the page and click Amazon's "Next Page" button to see more reviews. The extension automatically collects these new reviews. Keep clicking "Next Page" and letting it collect reviews until you have enough (we recommend at least 30-50 reviews for best results).

Step 5: When you're done collecting reviews, click the "Analyze Reviews" button on the floating button in the bottom-right corner. Wait about 30-60 seconds while our AI analyzes the reviews. When it's finished, click "View Analysis Results" and you'll be taken to nullfake.com where you can see the full report showing which reviews are fake and which are real.

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.
