Two all-in-one Amazon research tools with a lot of overlap. The deciding factors are how you source (desk vs in-store) and the track record you want behind your tool.
The short answer
Seller Assistant is a browser-based research tool. It runs in the browser only, with a side panel on supplier websites, a storefront widget, IP alerts and a bundled VPN.
SellerAmp SAS matches the core analysis (profit, ROI, eligibility, IP and hazmat alerts, estimated sales, offers and restrictions) and adds two things that matter for many sellers: a true mobile app with barcode scanning for retail arbitrage in stores, and Keepa-licensed history charts built into every lookup. It is also one of the most established tools in the space, used by 100,000+ sellers, with a large community and support behind it.
If you source in physical stores, want product discovery built in, or want a long-established tool with Keepa data inside, SellerAmp is the stronger all-rounder. The honest way to decide is to run both 14-day trials on the same deals.
