Show HN: Find hidden interests in Facebook Ads targeting

Hey HN, this is a weekend project I made and something I completed for the first time and released publicly. Thanks!

Nice idea in theory, but I&#x27;d recommend:<p>1. A demo of how it works, with some sample data<p>2. Some metrics about how using hidden interests materially changed the efficacy of your ads<p>Just some thoughts. Good luck!
