Arbitrage Stalker

One-click AI buy verdicts on any Amazon product page, profit calc + SatScore saturation analysis, and stalk any storefront.

Arbitrage Stalker puts an instant profitability read on every Amazon product page. Open any listing and see your numbers without leaving the page: Buy Box price, BSR, category, an exact fee breakdown, net profit, margin, ROI, and whether you're even allowed to sell it. New in 2.0: The AI Read. One click gets you a Strong Buy / Buy / Watch / Pass verdict on the product you are looking at, with the reasoning, the biggest risk, and a risk-adjusted max buy cost. Ask the AI free-form questions about any listing. Powered by your Arbitrage Stalker AI credits, with top-up packs when you run out. Built for online and retail arbitrage sellers who source fast and need the math to be right. What it does ──────────── • The AI Read: a one-click buy verdict (score 0-100, rationale, biggest risk, risk-adjusted max cost) on any product page, backed by stored price and sales-rank history when we have it and an honest lower-confidence page read when we don't • Ask anything: free-form AI questions about the product, grounded in the data on file • AI credit balance in the overlay and popup, with one-click access to top-up packs • Live profit calculator: type your buy cost and instantly see net profit, margin, and ROI for FBA or FBM • Real fee breakdown: referral fee by category (including split and tiered categories), media closing fees, and FBA fulfillment fees • Exact fees when you link your Seller account, accurate estimates when you don't • FBM shipping built in: carrier rates by zone and weight • Selling-eligibility badge: see "Can Sell" or "Restricted" before you buy • Max Buy price: the most you can pay and still hit your target return • Variation Viewer: sortable table of a parent's variations by reviews, price, and seller counts • One-click research shortcuts: price-history charts, marketplace price comparison, and seller-eligibility checks for the product you are viewing • Export to List: push a product (with your buy cost and source URL) straight into your buy lists • Works across the US, CA, UK, DE, FR, ES, IT, MX, JP, and AU marketplaces How it works ──────────── The extension reads the ASIN from the product page and asks your Arbitrage Stalker account for that product's data. Your numbers and lists live in your account, so they're the same in the extension and on the web dashboard. Requires a free Arbitrage Stalker account. Click "Log in" in the extension to connect: no copying API keys by hand. Privacy ─────── No analytics, no tracking, no telemetry. The extension only talks to Amazon (to read the product page) and to your Arbitrage Stalker account (to fetch profitability data). It never sees your Amazon password or seller credentials.
