Companion to the desk

Capture rival moves from the browser tabs you already have open.

A lightweight Shelfhawk companion that watches the storefronts competing with your shop, logs what they just changed, and feeds it back to your desk. No copy-paste, no scrapers, no overnight cron you forgot you turned on.

  • Captures price, stock, ad creative, and review signal from any open tab
  • Posts directly to your existing Shelfhawk watch surface — no separate seat
  • Hands off sensitive actions to the desk; the extension only watches
  • Built to stay out of your day — quiet until something actually moved

What we capture

Four signals, captured from one tab.

The extension reads from the pages you already have open, runs everything local to the browser tab, and posts a stripped event back to your desk. The watch agents on the desk pick up the signal and surface it the morning your rivals moved.

  1. 01
    01 · Price

    Live rival price

    Every visible price on the listings you have open is pulled into the price-watch agent on the desk. Sales, MAP floors, promo code flips, and shipping subsidies are tagged so you see the why, not just the new number.

  2. 02
    02 · Stock

    Stock state

    Quantity 0, low-stock warnings, and restocks are flagged the moment a tab re-renders. The desk correlates the quieting with the SKU so you can ride the demand that just rolled your way.

  3. 03
    03 · Ad creative

    New creative

    Sponsored display, sponsored brand video, and social posts surfaced on rival pages are captured and dropped into your creative library overnight, framed next to the offer they are pushing.

  4. 04
    04 · Reviews

    Review signal

    Stars, velocity, and topic mix on rival listings are mirrored into the review-monitor so you can spot the angle your competitors are missing — or the one your customers are quietly asking for.
