The big idea
TikTok's AI watches everything you do — what you watch, how long, what you skip, what you like. Then it picks the next video to keep you watching. That is why For You feels personal.
Some examples
- AI tracks how long you watch each video.
- AI tracks if you like, share, comment, or save.
- AI tracks if you watch a creator's other videos.
- AI tests new types of videos sometimes to learn what else you might like.
Try it!
Set a timer for TikTok use. Notice if you scroll past it. That is AI doing its job.
