    AI Chatbot Beginner's Guide

    ChatGPT, Gemini, Copilot, Claude — what each one is, when to use it, what not to trust it for.

    What is an AI chatbot, in one paragraph?

    You type a question; a computer program writes back in conversational English. Underneath, it has read large amounts of text and learned to predict good answers. It is not a person, not a search engine, and not always right — but it is fast, patient, and never tired of explaining the same thing twice.

    Why might I want to try one?

    • •Plain-English explanations of confusing things — Medicare, computer errors, medication names.
    • •Drafting letters you do not want to write from scratch.
    • •Practice conversations — what to say to the cable company\'s retention line, how to ask a question of your doctor.
    • •Recipes, ideas, vacation planning, language help — the assistant for the small daily questions.

    Good first prompts to try

    Plain-English explanation
    • "Explain Medicare Part D to me like I am 65 and have never heard of it."
    • "What is two-factor authentication, in plain English?"
    • "My doctor said I have something called atrial fibrillation. What is it?"
    Drafting letters and emails
    • "Write a polite letter to my homeowners association asking them to fix a streetlight."
    • "Help me write a thank-you note to my niece for the birthday gift."
    • "Draft an email asking my doctor for a prescription refill."
    Recipes and cooking
    • "I have chicken, broccoli, rice, and soy sauce. What can I make?"
    • "Convert 350°F to Celsius and explain why my cake recipe says both."
    • "What is a good substitute for buttermilk?"
    Practical help
    • "I need to call my bank about a charge I do not recognise. What should I say?"
    • "How do I get a passport renewed if I have moved since the last one?"
    • "Read this email I got and tell me if it sounds like a scam: [paste it]."

    Quick Tip: AI chatbots are at their best when you are SPECIFIC. "Help me write a letter" is okay; "Help me write a friendly letter to my HOA asking them to repaint a faded crosswalk" is much better.
