Free Amazon Review Analyzer
Paste any Amazon ASIN to see the full ratings breakdown, sentiment split, and top customer reviews — pulled live from Amazon.
No signup required. Try if you don’t have one handy.
Reviews tell you what the listing doesn’t
The star rating on an Amazon listing is a single number — but the reviews underneath it explain why the product converts (or doesn’t). The 1-star and 2-star reviews surface the real objections shoppers have. The 5-star reviews tell you which features are doing the heavy lifting.
This tool gives you that distribution at a glance — plus a ready-made sample of positive and critical reviews to read through. For deeper analysis, pull the same data into your own code with the Canopy API’s Amazon Reviews endpoint.

The Amazon Reviews API, in one query
This tool is a thin wrapper around the Canopy API’s reviews endpoint — the same data, structured and paginated, available over REST, GraphQL, MCP, and as an LLM skill. Drop the GraphQL query on the right into your app to pull reviews for any ASIN.

How do I see all reviews for an Amazon product?
Paste the product’s 10-character ASIN above. You’ll get the full ratings breakdown plus a sample of the top customer reviews surfaced by Amazon. For the complete history of reviews — up to Amazon’s 500-review cap per product — use the Canopy Amazon Reviews API programmatically.
Is there a free Amazon reviews API?
Yes. This tool runs on the Canopy API, which exposes Amazon product reviews over REST, GraphQL, MCP, and as an LLM skill. There’s a generous free tier for small projects, and pricing scales with usage if you need to track reviews across many ASINs.
What does the ratings breakdown show?
The number and percentage of 1, 2, 3, 4, and 5-star ratings for the product. We also compute the share of positive (4–5 star) and critical (1–2 star) ratings so you can see sentiment at a glance.
Does this scrape Amazon?
No scraping on your end — and no proxies, headless browsers, or accounts required. Every request goes through the Canopy API, the same Amazon data pipeline our paying customers use in production.
Where do I find the ASIN?
In the product URL, right after "/dp/" (for example, amazon.com/dp/B0F7K8DPPT). You can also find it in the "Product Details" section near the bottom of any listing.
Is this tool free?
Yes. No signup, no API key. A small per-IP rate limit keeps it fair. For higher volume or programmatic access, grab an API key.
Need reviews data in your own app?
The Canopy API gives you the same Amazon review data over REST, GraphQL, MCP, or as an LLM skill — at scale, with a generous free tier.
