AmzCompanion is a Chrome extension for Amazon sellers who need to size up competition before they source, price, or list. It overlays live seller and inventory intelligence directly on any Amazon product page — so you get the answer in 2 seconds instead of 20 minutes of manual checking. ───────────── WHAT YOU SEE ON EVERY LISTING No CSV uploads. No dashboards. No pasting ASINs into a research tool. It's just there, on the page you're already looking at. ───────────── WHAT SELLERS USE IT FOR ───────────── WHY IT'S DIFFERENT Most Amazon seller tools (Jungle Scout, Helium 10, Keepa) pull you into a separate dashboard and ask you to paste in ASINs or upload files. AmzCompanion runs inline, on the product page itself — because that's where you already are when you're making a sourcing or pricing call. It's a focused tool that does one thing well. Not a suite. Not a subscription you'll only use 10% of. ───────────── TRIAL & PRICING ───────────── WORKS ON ───────────── PRIVACY AmzCompanion only reads the information on Amazon product pages it needs to calculate inventory insights. It does not: If you have an active subscription, the extension contacts our servers to verify your license status. That's it.
