Hey Hacker News,<p>I built this tool around uncovering Facebook advertising interests.<p>For each keyword you put in the ads manager, Facebook™ shows only 25 interest suggestions, the same that it shows to everybody.<p>Turns out more interests are just an API call away. If you are a dev, it's pretty simple but I thought to develop a free tool for non-technical people.<p>This was a small feature of a product I built almost three years ago and decided to give it new life.<p>It's entirely free to use.<p>Hope you like it!
