A real run
Checked Oct 11, 2026, on the home pages of Nubank and Inter (our check of inter.co landed on its US page, which loads the same tracking setup as the Brazilian one); the same day the check found no ad tracking codes on RD Station and Conta Azul. Pages change. Brands are examples; not affiliated.
Nubank and Inter share the same 7 ad platforms, Pinterest and X included; Inter adds an 8th, Criteo, the banner ads that follow you to other sites.
Both: Google, Meta (Facebook and Instagram), TikTok, LinkedIn, X, Pinterest and Microsoft. Inter's tracking lists 8 Google Ads account numbers and Nubank's lists 2; some may be old, like the retired Google Analytics code both still carry.
Both also use Google Analytics and two screen-recording tools (Hotjar and Microsoft Clarity). Inter also runs Statsig for A/B tests.
We ran the same check on two Brazilian software companies, RD Station and Conta Azul, and found no ad tracking codes. Some sites load them only after you accept cookies, so an empty result means we could not see them, not that they run no ads.
What you do with it: check both banks in Meta's Ad Library and Google's Ads Transparency Center, then visit inter.co and watch for its banners on other sites. A tracking code shows the setup, not the spend.

Questions
Where does the data come from?
From the public page itself: its code, its cookies and the tracking setups it loads. No outside database.
Does a tracking code mean they are running ads there?
It means the site is set up to measure visitors for that platform, which companies do when they advertise or plan to. It does not show spend or which ads run.
How accurate is it?
It names a tool only from an account number, a tracking code type or the tool’s own code, not from a word on the page. Tools that load only after a click, a login or a cookie choice can be missed, so a short or empty list can mean the site loads its codes later.
Will the competitor know?
They see one ordinary visit to their page.
What does it cost?
Nothing; it is free. New accounts also get $5 to try the paid use cases.
How often should I run it?
Monthly, or before planning a campaign. Ask your AI assistant to check your top competitors and compare them.
