SellerBowl Chrome Extension

The SellerBowl Chrome Extension brings powerful product research data directly into your Amazon browsing experience. Instead of switching between tabs and tools, you get instant access to sales estimates, profit calculations, and competitive intelligence right on the Amazon product page you are already viewing.

Once installed, the extension automatically detects when you are on an Amazon product page and displays a compact data overlay with the metrics that matter most: estimated monthly sales, revenue, BSR rank and category, number of sellers, FBA fee breakdown, and net profit calculation based on your cost of goods. This instant snapshot lets you evaluate products in seconds as you browse Amazon — no need to copy ASINs into a separate tool.

The built-in Profit Calculator goes beyond basic fee estimation. Enter your product cost, shipping cost, and desired margin, and the extension calculates your net profit after all Amazon fees (referral fee, FBA fulfillment fee, storage fees, and closing fees). It accounts for category-specific fee structures and updates automatically when Amazon changes its fee schedule. For arbitrage sellers scanning retail stores, this means you can check profitability on your phone in real time.

Price History charts show you how a product's price has changed over the past 30, 90, and 365 days. Identify products with stable pricing (good for wholesale) versus products with frequent price drops (risky for inventory-heavy models). The extension also flags products currently priced significantly above or below their historical average.

Review Sentiment Analysis breaks down customer reviews into positive, negative, and neutral categories with keyword extraction. Quickly understand what customers love and hate about a product without reading hundreds of reviews. This is invaluable for private label sellers looking to improve on existing products — the extension highlights the exact pain points you can address in your version.

The Supplier Search feature lets you find potential suppliers and manufacturers for any product you are viewing. It searches across wholesale directories and manufacturer databases to surface sourcing options with estimated pricing. Combined with the profit calculator, you can evaluate the full sourcing-to-selling pipeline without leaving Amazon.

The extension is completely free for all SellerBowl users and works on all Amazon marketplaces (US, UK, DE, FR, IT, ES, CA, JP, AU, and more). It syncs with your SellerBowl account so saved products and research history are accessible from both the extension and the web dashboard.
