Getting started with AI chat assistants: prompting basics

How to choose a free AI assistant, write clear requests (prompts) that get useful answers, and avoid common beginner mistakes.

5 min read · Updated · Written and checked by real people

AI chat assistants like ChatGPT, Claude, Gemini and Microsoft Copilot can feel a little intimidating at first. What do you type? Will you “break” it? Here’s the reassuring truth: you can’t break it, and talking to an AI assistant is a lot like giving instructions to a helpful new colleague. The clearer you are, the better the help you get.

Step 1: Pick one assistant to start

All of the big assistants have free versions, and any of them is a fine place to begin:

  • ChatGPT (OpenAI): a popular all-rounder
  • Claude (Anthropic): strong with long documents and careful writing
  • Gemini (Google): handy if you use Gmail and Google Docs
  • Microsoft Copilot: built into Windows and Microsoft 365

Choose one, create an account, and stick with it for a couple of weeks while you learn. You can always try others later. (See our tool pages for current free and paid plans.)

Step 2: Understand what a “prompt” is

A prompt is simply what you type (or say) to the AI. It can be a question, a request or a set of instructions. There’s no special code or magic words. Plain, everyday language works best.

Step 3: Use the “four-part” recipe

The companies that make these tools publish advice on writing good prompts, and it comes down to a few common ideas: be clear and specific, give context and say what you want the result to look like (OpenAI; Anthropic). An easy way to remember it:

  1. Task: What do you want? (“Write an email…”)
  2. Context: What’s the background? (“…to my landlord about a leaking kitchen tap that’s been broken for two weeks…”)
  3. Tone or role: How should it sound? (“…polite but firm…”)
  4. Format: What should the result look like? (“…under 150 words, with a clear subject line.”)

Before and after

Vague prompt:

Write an email to my landlord.

Clear prompt:

Write a polite but firm email to my landlord asking them to fix a leaking kitchen tap. It’s been leaking for two weeks and I reported it once already on May 3. Keep it under 150 words and include a subject line.

The second version gives the AI everything it needs, so you’ll spend less time fixing the result.

Step 4: Have a conversation

You don’t have to get it perfect the first time. The real power is in the follow-up. Try:

  • “Make it shorter.”
  • “Make it sound friendlier.”
  • “Give me three other options.”
  • “Explain that like I’m new to the topic.”
  • “Put that in a table.”
  • “What questions should I ask a professional about this?”

Treat it like a back-and-forth with an assistant who’s happy to revise as many times as you like.

Helpful prompt starters

Here are some everyday prompts to try:

  • Explaining: “Explain what a 401(k) is in simple terms, with an example.”
  • Summarizing: “Summarize this article in five bullet points: [paste text].”
  • Planning: “Create a 7-day meal plan for two people on a budget, with a shopping list.”
  • Writing: “Help me write a thank-you note to my child’s teacher.”
  • Learning: “Quiz me with 5 questions on basic Spanish greetings.”
  • Deciding: “Help me compare two job offers. Ask me questions first.”

That last one is a great trick: ask the AI to ask you questions first. It helps it understand what you really need.

Step 5: Give it examples

If you want something in a particular style, show it. For example: “Here’s a social post I liked: [example]. Write three more like it about our weekend bakery special.” Both OpenAI and Anthropic recommend examples as one of the most effective ways to guide the result (OpenAI; Anthropic).

Common beginner mistakes (and easy fixes)

  • Being too vague. Add who, what, why and how long.
  • Accepting the first answer. Ask for changes, more options or simpler wording.
  • Trusting every fact. AI can make things up. Double-check names, numbers, dates and quotes, especially for health, money or legal topics.
  • Sharing private information. Don’t paste passwords, ID numbers or other people’s personal details. Use placeholders like “[my address]”.
  • Giving up too soon. If an answer misses the mark, rephrase and try again. That’s normal, not failure.

Good to know

  • Free versions have limits. You may hit a daily cap or get a less powerful model. That’s fine for learning.
  • Some assistants can search the web, which helps with recent news, but still check the links.
  • You can usually delete chats or turn off chat history in the settings.
  • Voice mode on phone apps lets you just talk, which many beginners find easier.

Practice for 10 minutes

Try this today:

  1. Ask your assistant to explain something you’ve always wondered about.
  2. Ask a follow-up: “Can you give me a real-life example?”
  3. Ask it to turn the answer into a short checklist.
  4. Check one fact from the answer on a trusted website.

That’s it. You’ve just practiced the core skills: asking clearly, refining and verifying.

The takeaway

Good prompting isn’t a technical skill. It’s clear communication. Say what you want, give some background, describe the result you’d like, and keep the conversation going. With a little practice, an AI assistant can become one of the most useful tools you have.
