Overview
Grade selected product-page copy against 13 fixed buying-fact checks. No AI and no text upload.
Grade the copy on any product page against 13 fixed buying-fact checks, and see exactly which facts a buyer still has to guess. Select the text on a product page and click "Use selected page text", or paste the copy into the popup. You get a score out of 100, the three largest gaps written as concrete instructions, and the full list of 13 checks with the points each one earned. WHAT IT CHECKS The 13 checks cover the facts a buyer needs before deciding: numeric specs, materials, fit and compatibility, what is in the box, sizing guidance, care and durability, shipping and delivery, returns, warranty, who the product is not for, comparison against alternatives, proof and testing, and the use cases it is built for. HOW IT WORKS The rules are fixed and deterministic. There is no AI and no model call, so the same text always produces the same score. That matters when you rewrite a page and want to know whether it actually improved. PRIVACY Your text is graded inside the popup and is never uploaded. The extension asks for two permissions only: activeTab, to read the text you selected on the page you are looking at, and scripting, to read that selection. It has no host permissions, no analytics, no accounts, and no background page. WHO IT IS FOR Shop owners, product page writers, and anyone shipping ecommerce copy who wants a repeatable check before publishing. It is English only. A web version with a longer report is available at cartgap.app.
