Chrome extension
The ad spy extension for the Ad Library
Ad spying right in Chrome: see how many days each ad has been running, keep only the scaling ones, let the library scroll on its own and save the winners to Spymine.

What the ad spy extension shows in the library
The Spymine ad spy extension works inside the Ad Library, in your Chrome: every ad gets what’s missing to tell whether it sells.
Days running on every ad
The badge shows how many days the ad has been running, the format and the versions — no math from the date.
Only the scaling ones
"Scaling only" keeps just the ads running for more than 30 days and with more than 2 versions: the advertiser keeps and repeats them, a sign they sell.
Auto-scroll
The extension scrolls the library on its own as far as you choose, and the days, format and version filters apply right away.
A CSV spreadsheet
The ads that pass the filters go to a spreadsheet, with the days running, the versions and the links of each one.
Download the media
The video or image of each ad, in one click, to study with your team.
Save to Spymine
The ad goes to your Saved, in a folder just for the extension — even one Spymine doesn’t have yet.
Ad spying on the real library
The window sits in the corner, on top of the library, without squeezing the page. Click it to open the large one.

Search, inside the library
The term, the country, the language and the platform: the extension opens the search and scrolls on its own.

Filters apply right away
"More than 30 days", the format, the versions and "Scaling only": what doesn’t pass leaves the screen.

Each ad’s buttons
Open the advertiser’s page and their ads, copy the text, download the media and save.

Saved to Spymine
The notice says where the ad was kept, with "View" and "Undo".
The Ad Library alone vs. with the ad spy
The Ad Library shows the ads. The ad spy extension shows which ones are selling.
| What you want | The library alone | With the extension |
|---|---|---|
| Know how many days an ad has been running | You count from the date | The badge shows it |
| Find the scaling ones | You open them one by one | "Scaling only" sorts them out |
| Load more ads | You scroll the page | It scrolls on its own |
| Take them to a spreadsheet | You copy them by hand | The CSV takes them |
| Keep a good ad | You take a screenshot | Save keeps it in Spymine |
