AMZShark is a free service for Amazon sellers to search hundreds of millions of reviews by keyword, with millions more reviews being added daily.
Free to use. No payment required.
Keyword searches turn scattered Amazon reviews into a focused feed of product gaps, buyer language, and competitor signals.
Create a keyword search for defects, use cases, gift intent, materials, fit, durability, packaging, or any phrase buyers repeat.
Use broad product language or precise buyer complaints, then filter by marketplace, rating, and discovery date.
Paste ASINs, pull Amazon search results, or search products already known to AMZShark when you need a durable product set.
Enter a keyword, choose a marketplace, and decide whether to match product titles, review titles, review text, or all three.
Find repeated complaints, positive phrases, rating patterns, and products gaining fresh review activity.
Keep research clean with cursor-based exports that deliver only newly discovered matching reviews.
AMZShark is free for sellers who need keyword searches, product searches, filters, and exports from the same fresh review dataset.
