Questions
Yes. The Chrome helper is free for Meta Ad Library research: Shopify highlighting, days live, filters, auto scan, winners, downloads, Store X-ray and duplicate grouping. Remixing creatives into your own product ads happens in OnPromptAds Brands, which has a free start with no card required.
No. Chrome on phones does not run extensions. Install Ad Spy in Chrome on a computer, then open Meta Ad Library there.
It checks where each ad's landing page goes and looks for Shopify storefront signals. Ads that are not Shopify stay visible or hide when you choose Shopify only.
Only where Meta publishes reach, which is the EU, UK and Brazil. There Ad Spy estimates spend from that reach and a CPM you can adjust. Everywhere else it shows a scaling score from days live, number of variants and active status, so you can still rank ads. Meta never publishes exact spend, so treat every figure as an estimate.
Yes. Hover any ad and click download to save its video or images. The download button in the dock saves up to 50 visible ads as one ZIP with a CSV of copy, CTA, landing page and days live. Files go to your own computer only.
On any Shopify ad, Store X-ray reads the store's public pages and shows its likely best sellers, newest products, price range, theme and about 40 common apps and pixels such as Klaviyo, Judge.me and the Meta Pixel.
No. OnPromptAds Ad Spy is independent and not affiliated with Meta or Shopify.
EcomFilter-style tools filter Shopify ads in Ad Library, often behind a paid plan. Ad Spy does that for free, adds days live, filters, auto scan, downloads and Store X-ray, and continues into OnPromptAds Remix so you can turn a creative you like into new ads for your own products.
Install from the Chrome Web Store: https://chromewebstore.google.com/detail/onpromptads-ad-spy-shopif/gongikpcecnjainkfoenjnidfbmemodn. Click Add to Chrome, then open Meta Ad Library.
Read the Ad Spy Privacy Policy at https://brands.onpromptads.com/ad-spy/privacy/. It covers what the Chrome extension collects in Meta Ad Library research. The main Brands Privacy Policy also applies when you sign in to OnPromptAds Brands.
Your next Ad Library search, without the junk
