What is ChatGPT — and should you try it?

You have probably heard the name ChatGPT by now. Maybe your grandchild mentioned it at dinner, or you saw it on the news. Perhaps someone at your local library said it can write letters, answer questions, or help plan a trip. And you thought: that sounds useful, but also a bit mysterious.

You are not wrong on either count. This week, I want to explain what ChatGPT actually is, in plain English — no computer science required. And then I will tell you honestly whether I think you should try it, and how to do so safely.

So — what is it, exactly?

ChatGPT is a computer program made by a company called OpenAI. You type a question or request into a box, the same way you might send a text message, and it writes back an answer — in sentences, like a person would.

The “AI” part stands for artificial intelligence (which just means a program that can learn and respond, rather than just following rigid rules). ChatGPT was trained by reading an enormous amount of text from books, websites, and articles — and from all that reading, it learned how to write and respond naturally in English.

Think of it like this: imagine a very well-read research assistant who has read almost every book ever written, never sleeps, and responds instantly. That is not a perfect analogy, but it is a useful one.

What can it actually do?

Here are some things real Lumpost readers have used ChatGPT for:

• →Writing a letter to their insurance company after a dispute
• →Getting a simple explanation of a medical term their doctor used
• →Planning a week-long trip to Prince Edward Island
• →Understanding a confusing paragraph in a contract
• →Coming up with a birthday message for a grandchild

Notice that none of those involve being “good at technology.” They are just ordinary tasks that happen to be easier with a helpful assistant.

Is it safe to use?

For the kinds of uses listed above — yes, with a few important things to keep in mind.

Never share personal information with ChatGPT. This means no social insurance numbers, no passwords, no banking details, no full addresses. Treat it like a public search engine — useful, but not a place for private information.

It sometimes gets things wrong. ChatGPT is confident — but not always accurate. For anything important (medical, legal, financial), always verify with a professional. Use it to get a starting point, not a final answer.

You do not need an account to try it. You can go to chat.openai.com and try it without signing up. (Though creating a free account lets you save your conversations.)

Should you try it?

Yes — I think you should. Not because it will change your life, but because being curious about new things is healthy. And understanding what ChatGPT is, even just a little, means the next time someone brings it up, you will know what they are talking about.

If you try it and find it useful: wonderful. If you try it and find it strange or not worth your time: also completely fine. The goal is not to use every new tool. The goal is to understand your options.
