Reveal Reach (also listed as Reveal Ad Library Reach & estimate Adspend in the Chrome Web Store) is a free Chrome extension from Pantheon that runs on top of Meta's public Ads Library. After you search ads for an EU country, it opens ad details for you and writes Meta's Digital Services Act EU reach figure onto each card, including grouped creatives.
It exists because the Ads Library already publishes EU reach under the DSA, but the number sits behind per-ad detail panels and is awkward to compare at page scale. Reveal Reach turns that into a scan-and-sort workflow: analyze the visible results, sort by reach, and estimate spend with your own CPM and frequency.
The concrete differentiator is that reach and report data stay in the browser tab. Account data uses Google Firebase; the Ads Library figures themselves are not uploaded to Pantheon servers according to the product privacy policy.
