Artificial Intelligence, or AI, is software that does jobs we usually think need a human mind. It can write text, answer questions, summarize long documents, and recognize faces or voices. Many of the chatbots people use today run on a large language model. This kind of AI learned from a huge amount of text and works by guessing the next likely word, over and over, to build sentences.
This is the key idea to remember: the AI is predicting words that sound right. It is not looking up a fact in a trusted book or checking whether something is true. Because of this, an AI can give you a smooth, confident answer that is simply wrong. When an AI makes up facts, names, or sources, we call that a hallucination.
The tone of an AI answer does not tell you if it is correct. A wrong answer and a right answer can both sound polished and certain. That is why your own judgment still matters.
| AI is good at | AI is risky at |
|---|---|
| Drafting and rewording text | Giving exact facts, dates, and numbers |
| Summarizing what you give it | Naming real sources or quotes |
| Brainstorming ideas | Medical, legal, or money advice |
| Explaining ideas simply | Anything where being wrong causes harm |
Use AI as a fast first helper, not as the final word. Treat its answers like a draft from a clever but careless assistant: useful, but always worth checking.
