Amazon review analysis
Amazon review analyzer: what buyers praise, what they complain about, and how often

Aspect counts are Amazon’s own summary in the product details (all reviews, counts as Amazon reports them). The last column counts the same aspect in the 8 top reviews retrieved.
4.4 stars, but durability splits buyers
Cleaning is praised, but not by everyone
6 of the 8 top reviews are about other models
The most helpful review is a 3-star one about a different unit
Every figure was checked against the product details and review responses saved from this run. The 8 top reviews are the sample Amazon shows first, not all reviews, and 6 of them were written for other variants of the same listing.
Run it for your own product or accountHow it works
Read the product details
Title, price, star rating, rating count, star distribution, Amazon’s review aspect summary and Best Sellers Rank.
Read the top reviews
Stars, date, text and helpful votes for the reviews Amazon shows first, including whether each one is about a different variant.
Count by aspect
Praise and complaints are sorted by aspect and counted. 1–2 star complaints are grouped by cause when the sample includes them.
Turn it into listing changes
Three points to stress and three to fix or explain, each with the counts behind it.
What it cannot do
It reads the product details and the top reviews Amazon shows, not the full text of every review. Aspect counts come from Amazon’s summary; top-review counts are a sample. It does not detect fake reviews, and it does not include sales data beyond what Amazon shows on the listing.
Questions
How do I analyze Amazon reviews?
Look past the average rating: check the star distribution, the praise and complaints per aspect, and the reasons behind low ratings. Paste an ASIN into Nolyn and it pulls the product details and top reviews and returns those with counts, noting when the top reviews contain no 1–2 star reviews.
Is there a free Amazon review analyzer?
You can view the example and prepare the brief without an account. Running it requires signing in; new accounts get 100 credits. Each run uses credits for the AI and the Amazon data it retrieves.
What does an AI review analysis tell you?
Which aspects buyers like, where complaints cluster, and whether low ratings come from the product or from missing information. In the humidifier example, quiet operation was praised almost everywhere while durability drew more negative than positive mentions.
Can I analyze a competitor’s reviews?
Yes. Any public product works, yours or a competitor’s. A competitor’s most common complaints are candidates for what your listing can promise and prove.
Does it check fake reviews?
No. It summarizes what reviews say and flags reviews written for a different variant, but it does not score reviews for authenticity.
Which marketplaces are supported?
Amazon.com (US) and Amazon.co.jp (Japan) are available in the form.
