MerchScope overlays real numbers on every Amazon listing, every Shopify store, and every TikTok Shop product. Sales estimate, BSR history, FBA fee breakdown, review sentiment, and competitor pricing - the second the page loads.
Works inside your own browser. Cancel anytime.
One extension, three platforms. The numbers you need are already there - no exporting, no tab switching, no spreadsheet math.
Monthly units sold, revenue, and BSR history for every ASIN. Pulled from the live listing - no manual lookups.
Referral, fulfillment, storage, prep - all itemized. Tune your COGS and prep cost once and every listing shows true net margin.
Detects Shopify on any domain. Top products, catalog size, storefront traffic estimate, and which apps the store runs.
Units sold, revenue estimate, creator commission rate, and which videos drive each product. Spot rising products before they peak.
Sentiment score and complaint themes pulled from the most recent reviews. Find listings where buyers are unhappy with the leader.
Group products into niches to compare side by side. Set alerts for price drops, BSR breakouts, and new reviews on tracked items.
Most research tools cover one platform. MerchScope covers all three marketplaces sellers actually compete on today.

Short answers to the questions sellers ask before signing up.
MerchScope reads the BSR and category off the live Amazon listing and runs it through a rank-to-sales curve per category. For Shopify and TikTok Shop we use publicly visible signals (sold counts, listing dates, top-product positioning). Treat all numbers as directional, not exact.
Yes. MerchScope only reads publicly visible product pages - the same data any shopper can see. It never logs into Seller Central, never automates orders, and never makes changes to your listings.
We detect Shopify on any domain by looking for the standard Shopify markers (cdn.shopify.com assets, the Shopify global, meta tags) and then fetch the storefront's public /products.json feed to enumerate the catalog.
Yes. The same package installs on Microsoft Edge from the Edge Add-ons store. Manifest V3, no separate build.
Yes - cancel from your dashboard at any time. You keep access through the end of the current billing period. No contracts, no cancellation fees.
