Start Here: What Is AI?
Artificial intelligence (AI) is software that can do things we used to think only people could do, like understanding a question written in everyday words and answering it, writing a letter, or describing a photo. Today's popular AI assistants (ChatGPT, Claude, Gemini, Grok, Copilot) work like a chat: you type or speak, and they reply. Under the hood they learned patterns from enormous amounts of text, which makes them remarkably useful, but also capable of being confidently wrong.
Key takeaways
- AI is just software you talk to in normal language; if you can text, you can use it.
- It learned by studying huge amounts of writing, so it's great at words: drafting, explaining, summarizing.
- It can 'hallucinate' (state false things confidently), so check anything important.
- Think of it as a fast, well-read assistant, not an all-knowing authority.
