ChatGPT is free to use at chat.openai.com — no account required for basic use, though a free account unlocks more features. But most people who try it type something vague, get a generic answer, and give up.

The difference between a useful response and a useless one almost always comes down to the prompt. A good prompt gives ChatGPT context, a clear task, and a format to follow. A bad prompt gives it nothing to work with.

This guide gives you 100 prompts that actually work — organised by what you're trying to do. Every prompt here is written to work on the free version of ChatGPT (GPT-4o mini or GPT-3.5). Copy them directly, or swap out the bracketed parts for your own details.

How to Use This Guide

Each prompt uses square brackets [like this] to mark the parts you should replace with your own information. Everything else you can copy and paste directly into ChatGPT.

For best results:

• Be specific. The more context you give, the better the answer.
• Ask for a format. Saying "give me a numbered list" or "write this as a short paragraph" shapes the output.
• Iterate. If the first answer isn't quite right, follow up with "make it shorter", "make it more formal", or "try again with a different angle".

A Note on Prompt 100

That last one is deliberate. ChatGPT is a language model — it generates plausible-sounding text based on patterns in its training data. It can be wrong. It can be confidently wrong. It doesn't browse the internet in real time unless you're using a version with web search enabled.

For anything that matters — medical decisions, legal situations, financial choices, or anything you're going to act on — treat ChatGPT's output as a starting point, not a final answer. Use it to understand a topic, draft a document, or structure your thinking. Then verify the important parts with a qualified professional or a reliable source.

Used that way, it's one of the most useful free tools available to Australians right now.

Quick Tips for Better Prompts

Give it a role. Starting with "You are an experienced [role]" can improve the quality of specialised responses. Try "You are an experienced Australian accountant" before asking tax questions.

Set the format. "Give me a numbered list", "write this as a table", "keep it under 100 words" — ChatGPT follows formatting instructions well.

Add constraints. "Don't use jargon", "assume I have no prior knowledge", "focus only on options available in Australia" — constraints narrow the output to what's actually useful.

Iterate. The first response is rarely the best one. Follow up with "make it more concise", "give me a different angle", or "now write a version for a more formal audience".

Save your best prompts. When you find a prompt that works well for a recurring task — a weekly report, a type of email, a research question — save it somewhere. A good prompt is reusable.
