SellerGPT

SellerGPT panel for Amazon product pages: profit calculator, price history, buy-box and offer intel, and sell-eligibility checks.

SellerGPT — profit intel on every Amazon product page Stop bouncing between a calculator, a price-history tool, and Seller Central. SellerGPT drops all of it into one panel, right on the Amazon listing, so you can judge a deal in seconds. Open any product and the panel appears in the right column: • Profit calculator — enter your cost and get profit, margin, ROI, and break-even max cost instantly, with FBA/FBM fees baked in. • Price & sales-rank history — see how the buy box, Amazon's price, and BSR have moved over time. • Buy box & offer intel — who's winning the buy box, how many sellers are on the listing, and whether Amazon is one of them. • Sell-eligibility check — know if you're approved (or gated) before you buy inventory. Sign in once and the panel rides your existing SellerGPT login — no extra passwords. It runs only on Amazon product pages and nothing else. Install it, open a product, and see your margins before you finish reading the title.
