Two full-featured Amazon research tools that overlap a lot. The deciding factors are which marketplaces you sell in and whether you want Keepa history built in.
The short answer
AZInsight (by asinzen) is a product-research tool for Amazon and Walmart sellers in the US: a profit calculator, stock checker, variation viewer, and its AZAlert brand-claim database for spotting IP risk. It focuses on Amazon.com and Walmart, with a community-reported brand-alert feed.
SellerAmp SAS covers the same core analysis (profit, ROI, eligibility, IP and hazmat alerts, estimated sales, offers and stock) and adds the things many sellers depend on: Keepa-licensed history charts in every lookup, UK and European marketplace support with VAT handling, a mobile app with barcode scanning for in-store retail arbitrage, and built-in product discovery (Advanced, Smart and Storefront search). It is also one of the most established tools in the category, used by 100,000+ sellers.
If you sell in the UK or Europe, source in stores, or want Keepa data inside your analysis, SAS covers more ground. The simplest test is to run both free trials on the same products.
