Ad Collector — the extension behind Ad Repository

Ad Repository has to get its ads from somewhere, and that somewhere is this extension. It sits quietly in Chrome, notices ads on Facebook, X (Twitter), Google Search, Google Display, Google Shopping, YouTube, Bing, Amazon, TikTok, Reddit, Pinterest, LinkedIn as you go about your normal browsing, and adds them to the public archive. You don't need it to search the archive — only to help fill it.

Add to Chrome — free Browse the archive instead

Install it

One click from the Chrome Web Store. No account, no setup screen to click through.

Keep browsing

It doesn't change anything about the sites it works on — it just notices ads already on the page as you scroll past them.

They land in the archive

What it picks up gets added to Ad Repository, where anyone can search it — no extension required on their end.

Frequently asked questions

Does it cost anything?+

No. It's free, and there's no account to make.

What does it actually collect?+

Just what's already visible on the page — the ad creative, the copy, who's running it, and whatever engagement numbers the platform is already showing. Nothing you couldn't see yourself by scrolling.

Do I need this to search Ad Repository?+

No, that part's separate. The archive at adsrepository.com is open to anyone. This extension is just how it grows.

Where does it work?+

Facebook, X (Twitter), Google Search, Google Display, Google Shopping, YouTube, Bing, Amazon, TikTok, Reddit, Pinterest, LinkedIn.
