The Store's Mind Reader
Look at a dinosaur toy on a website. Scroll down. The site shows you four more dinosaur toys. That's not magic — that's a recommendation AI.
It saw you click on dinosaurs. It also saw that lots of other kids who liked that dinosaur went on to like these other ones. So it puts them in front of you.
Why the store wants to guess
- Hopes you'll buy more
- Hopes you'll come back tomorrow
- Hopes you'll tell your friends
