What Epinium does in ChatGPT
The Epinium plugin answers questions about your Amazon business from your own data, without exporting a spreadsheet first. It covers your product catalog, your advertising, your performance figures and the automations you have set up in Epinium. It only reads this data.
The catalog merges the Seller Central, Vendor Central and Advertising views of each product. Ad data covers Sponsored Products, Brands and Display, with spend, sales, ACOS, ROAS, clicks and search terms. Seller and Vendor figures are reported separately, matching how the two models work.
Typical questions are which campaigns had the worst ACOS or which search terms spend budget without orders. Answers come back as tables you can sort and drill into. You need an Epinium account with at least one Amazon connection to use it.
