§ 01 — Anchor
What is AI used for?
AI is used across nearly every industry and daily activity. From the moment you wake up to a smart alarm, check navigation on your phone, read a filtered email inbox, and stream a recommended song — AI is present.
There is an important distinction between what AI can do (capability — generating text, recognising images, predicting outcomes) and what AI is used for (actual applications — virtual assistants, fraud detection, medical imaging). This page covers the latter: real-world uses, organised by domain.

§ 10 — The normative question
Not every problem needs AI.
Some problems are better solved with conventional software, human expertise, or structured processes. Knowing when not to use AI is as important as knowing when to use it.
That question — what should AI be used for, and what should remain human — is the subject of AI Logic Engineering.
