  description

  AmzCompanion – Inventory Intelligence helps Amazon sellers understand inventory signals and availability changes while viewing Amazon product pages.
  
  What it does
  • Displays inventory / stock insights directly on supported Amazon listings
  • Helps you monitor availability changes so you can react faster to restocks and sell-through
  • Lightweight, fast, and designed to stay out of your way while browsing
  
  How it works
  When you visit a supported Amazon product page, AmzCompanion reads the page information needed to calculate and display inventory insights in the extension UI.
  
  Who it’s for
  • Amazon sellers and operators
  • Anyone tracking stock movement and availability patterns on listings
  
  Privacy
  AmzCompanion only accesses the information required to provide the inventory insights on the pages you visit. If subscription/licensing features are enabled, the extension may contact our service to verify subscription status. We do not sell personal information.

  Know who you're really competing with — without leaving the Amazon listing.
  
  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
  
  - Every seller on the ASIN, with their estimated stock count
  - FBA vs FBM vs Amazon-direct split (both as counts and percentages)
  - Price, condition, Prime eligibility, and delivery estimate per seller
  - Filters for price range, seller type, condition, and stock
  - The total number of offers counted and the real-stock total
  
  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
  
  - Arbitrage & wholesale sellers — Spot low-stock competitors before they restock, so you can time your listing entry to capture the buy box.
  - Private-label sellers — Check whether any third-party sellers have piggybacked your listing and how much inventory they actually hold.
  - Agencies & VAs — Screen dozens of source-lead ASINs in the time it used to take to check one.
  - Anyone doing product research — Answer "is this listing worth entering?" from the seller distribution alone.
  
  ─────────────
  
  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.

  ─────────────
  
  PRIVACY
  
  AmzCompanion only reads the information on Amazon product pages it needs to calculate inventory insights. It does not:
  
  - Read your Amazon Seller Central data
  - Read any personal email, documents, or non-Amazon browsing
  - Sell or share your personal information
  - Track you across other sites
  
  If you have an active subscription, the extension contacts our servers to verify your license status. That's it.
