AI covers any technique that lets machines mimic aspects of human thinking. Early AI relied on hand-coded rules, while modern AI mostly learns patterns from data through machine learning.
You already use AI daily: it filters spam, recommends videos, powers maps and answers questions through assistants like ChatGPT. These systems do not think like people; they find statistical patterns in vast amounts of data and use them to predict, classify or generate.
For example, an AI trained on millions of photos can tell a cat from a dog without ever being told the rules that distinguish them — it learns the difference from examples. Explore practical AI in our AI tools directory.
