Your rivals changed their prices. You should hear it from us.

Promolexa watches up to three competitor storefronts every week, tells you exactly what moved, and hands you the counter-campaign already written — emails, social copy and a hero image, in your brand voice.

Most stores find out too late, and then answer badly

A competitor drops a price on a Tuesday. You notice a fortnight later, in a dashboard, as a dip you cannot explain. By then the campaign you would have run is pointless — and writing it from scratch under pressure is exactly when the copy comes out weakest. Promolexa closes both gaps: it catches the move within the week, and the response is drafted before you have even opened the alert.

The reason to install

Know the moment a rival moves

Add up to three competitor storefronts. Promolexa checks each one every week and tells you what actually changed — a new product, a price cut, a fresh promo on their homepage.

New products, price changes and promo copy, caught automatically
Every alert arrives with a counter-campaign already drafted
Written in your brand voice, from your own catalogue

Launch faster

A full launch kit from one product

Pick any product in your store. Promolexa writes the emails, the social copy and the product description variants, and generates a hero image to go with them.

3 email drafts, 5 social posts, 3 description variants
An AI hero image you can push straight onto the product
Send the emails from inside the app, or copy anything out

Know where you stand

A monthly read on your marketing

Promolexa scores your store out of 100 each month from your own order data — repeat-purchase rate, revenue trend, catalogue coverage — and explains what to fix first.

One score, recalculated every month
Plain-language recommendations, ranked
Built from your real orders, not survey averages

Running inside a week

Install from the Shopify App Store

Promolexa runs inside your Shopify admin. No separate account, no code, nothing to embed in your theme.

Add the rivals you actually worry about

Paste up to three storefront URLs. The first scan runs immediately so you see where they stand today.

Answer their next move the same week

When something changes, the alert already contains the campaign. Review it, adjust the tone, send it.

Questions merchants ask first

How does Promolexa track competitors?

You give it up to three competitor storefront URLs. Promolexa reads their public storefront each week — the same pages any shopper can see — and compares it against the previous scan to find new products, price movements and changed promotional copy.

What happens when a competitor changes something?

You get an alert describing the change, paired with a counter-campaign drafted from your own catalogue and brand voice. The point is that you are not left to write the response yourself at the moment you are least prepared to.

Does it post to social media for me?

Promolexa writes ready-to-publish social copy for every launch kit, and you publish it. Direct Facebook Page publishing is built and approved by Meta, and is finishing Meta's last verification step. Instagram, LinkedIn and X are planned after that.

Can it send the emails, or does it just draft them?

It sends them. Email delivery is live inside the app — pick the draft, set the recipient and subject, and send. You can also copy any draft out into whatever email platform you already use.

Which Shopify plans does it work on?

Any plan. Promolexa reads your products and orders through the standard Shopify Admin API and needs no theme changes, so there is nothing to break in your storefront.

What does it cost?

$29 per month with a 7-day free trial, billed through Shopify so it appears on your normal Shopify invoice. Cancel by uninstalling.
