The big idea
Spotify, TikTok, YouTube — they all use AI to pick what plays next. The AI watches every second of what you do (skip, watch fully, like, share) and uses that to pick stuff you will probably like.
Some examples
- TikTok's For You page is famous for being scary good at guessing what you want.
- Spotify's Discover Weekly playlist uses AI to find songs in your taste zone.
- YouTube's Up Next uses AI to keep you watching.
- The AI is always learning — your taste from yesterday teaches it about today.
Try it!
Notice for one day: how often does the next video/song feel weirdly perfect? That is AI doing its job — predicting your taste.
