They are doing nothing, just showing what all information is already there in the amazon page as a tool. Nothing useful.

click bait ads , they said it's totaly free , but it's not !!!! , the only data you get for the free version is the data already avaiable on kdp (, BSR , estimated sales) and you have to pay to get the information you need so yeah terrrible attempt to collect people emails.
