Half the reason AI feels scary is the words. Everyone throws around "ChatGPT" and "prompts" and "models" like you are supposed to already know them. You're not. Nobody handed you a manual. So here is our plain-English cheat sheet. No computer-science degree required. - AI: software that can write, answer questions, or make pictures. Not alive, not thinking like a person. Just very good at guessing what comes next. - AI chatbot: a program you type to, and it types back, like texting a very well-read helper. ChatGPT, Claude, Gemini, and Copilot are the big ones. - Prompt: just what you type to the AI. Your question or request. No secret words needed. - Model: a version of the AI, like a car model. "GPT-4" or "Claude" are models. Newer usually means smarter. - Hallucination: when AI confidently makes something up. Always double-check anything that matters, like a name, a date, or a money or health fact. That is plenty to start. We keep a growing list of these in the community, and here is the best part: if you hit a word that makes your eyes glaze over, comment it below. I will add it in plain English. We are building this together!
