Promolexa

Promolexa is a Shopify app that reads your competitors' stores every week and tells you what changed: products they launched, prices they cut or raised, and new sales and offers on their homepage. For each change it drafts a response (an email and a social post) you can send from the app. It also builds launch kits for your own products and scores your store's health every month. Before Black Friday, when every brand is quietly changing its store, it's the cheapest way to know what your rivals are doing. Free plan tracks one competitor weekly; Standard is $29/month for three.
