Application of AI in mass projects today?

Question

Artificial intelligence

Interested in examples of mass (aimed at ordinary users, for solving everyday, trivial tasks) projects based on the elementary ai (classifier).
What came to my mind:
google (search, especially by images; translator)
soundcloud (formation of a playlist and recommendations)
telegram (selection of call parameters, as they say)
amazon (selection of related products)
prisma (quickly fading toy, similar examples not interested)

AI is used at IBM for solutions in the form of Watson, which this year calculated taxes for half of the US population, and in a bunch of projects related to healthcare.
AI is used in intrusion prevention systems to detect anomalies in the behavior of users and systems.
The most familiar mainstream solution is Fine Reader, which has been around for a very long time.
