How to Use ChatGPT: A Beginner's Guide (2026)
To use ChatGPT well, create a free account, then give it a clear instruction: who it should act as, the situation, exactly what you want and how the answer should look. Start with everyday tasks such as summarising, drafting and planning, check any facts that matter, and improve each answer by asking for one specific change at a time. It works in a web browser or an app, and you do not need to code.
ChatGPT is an AI assistant that you talk to in plain language. This guide shows you how to start, what to use it for, how to write prompts that get useful answers, and how to avoid the common mistakes. Features and plans change often, so check the official help pages for what your account includes.
Get started in five minutes
- Open the website or app and create an account with your email.
- Choose the free plan to begin. Paid plans add higher limits and extra features, and you can decide later.
- Type a request in the message box, then press enter.
- Read the answer and reply with a change, such as "shorter" or "add a table".
- Start a new chat for a new topic so earlier messages do not confuse it.
How to write a good prompt
Most weak answers come from vague requests. Use this five-part structure:
- Role: who ChatGPT should act as, such as an editor or a patient tutor.
- Context: your situation and any facts it needs.
- Task: exactly what to do, in one clear instruction.
- Format: how the answer should look, such as a table, five bullets or 150 words.
- Limits: what to avoid, and to say when it is unsure instead of guessing.
Our free seven-day prompting plan builds this skill with a project each day, and our guide to writing better prompts goes deeper.
Ten everyday things to try first
| Task | Try this |
|---|---|
| Summarise something long | Paste an article and ask for a two-sentence overview, five key points and three open questions |
| Draft or fix an email | Say who it is for, what you want them to do and the tone |
| Plan your week | Give your goals, hours and fixed commitments, and ask for a table |
| Explain a hard topic | Ask it to explain like you are new to it, with two examples |
| Brainstorm ideas | Ask for ten options, then ask it to rank them against your criteria |
| Study and revise | Ask it to quiz you one question at a time and explain mistakes |
| Prepare for an interview | Ask it to play the interviewer and give feedback on your answers |
| Turn notes into a post | Paste notes and ask for 150 words in your own voice |
| Analyse a spreadsheet | Upload a file, if your plan allows, and ask for trends and a chart |
| Compare options | Ask for a table of pros, cons and costs, then check the facts |
How to use ChatGPT for work
- Reports and presentations: outline first, then draft section by section, then edit in your own voice.
- Research: ask for a one-page brief with sources and dates, then open the sources yourself.
- Meetings: paste your notes and ask for decisions, owners and next steps.
- Customer replies: ask for a draft in your company's tone, and review before sending.
- Repeat tasks: save your best prompts in one document, and consider an automation once a task is stable. See our AI automation guide.

- Give more context. Your goal, audience and constraints make the biggest difference.
- Show an example of the output you want, then ask for more like it.
- Iterate. Treat the first answer as a draft and ask for one specific change.
- Ask for its reasoning or assumptions when the topic is complex.
- Ask it to say when it is unsure and to ask you questions before it starts.
- Use the extra tools your plan offers, such as file upload, web search and saved instructions, when they fit the task.
What ChatGPT cannot do well
- It can be wrong with confidence. This is called a hallucination. Verify names, numbers, dates and quotes. See our glossary entry on AI hallucination.
- Its knowledge has limits. It may not know very recent events unless it can search.
- It is not an expert adviser. Do not rely on it alone for medical, legal, tax or investment decisions.
- It does not replace your judgment. You are responsible for what you use.
Use it safely
- Do not paste passwords, bank details, client data or private records.
- Check the privacy and data settings in your account, including whether chats are used to improve the models.
- Follow your employer's rules about AI tools.
- Tell people when AI helped produce something if it matters to them.
Common beginner mistakes
- Asking one vague question and giving up.
- Accepting the first answer without checking facts.
- Changing many things at once, so you cannot tell what helped.
- Collecting hundreds of prompts instead of practising a few.
- Using one long chat for everything.
