ChatGPT is the most widely used AI assistant in the world, but most people only scratch the surface. They type a short question, get a generic answer and decide AI is “fine, I guess”. This guide shows you how to use ChatGPT properly, from your very first chat to the features that save serious time: file uploads, web search, projects, memory, voice, images and custom instructions.
Everything here works on the free plan unless we say otherwise.
Step 1: Create your account
- Go to chatgpt.com or download the ChatGPT app for iPhone, Android, Mac or Windows. Only download from the official site or your device’s official app store.
- Choose Sign up and use your email, Google, Microsoft or Apple account.
- Verify your email and enter your name and date of birth.
You can also try ChatGPT without logging in, but you will not get chat history, file uploads or memory, so an account is worth it.
Step 2: Understand the screen
- Message box: where you type. The + button lets you attach files and photos or pick tools like image creation, deep research or web search.
- Sidebar: your chat history, projects and custom GPTs.
- Model picker: on paid plans, choose between fast replies and slower “thinking” responses for harder problems.
- Voice button: start a spoken conversation.
Step 3: Write your first good prompt
The biggest difference between frustrating and useful ChatGPT answers is the prompt. A simple formula works for almost everything:
Role + task + context + format.
Weak prompt: “Write an email about the meeting.”
Strong prompt: “You are my assistant. Write a short, friendly email to my team moving Thursday’s 2pm project meeting to Friday at 11am because the client call ran over. Keep it under 80 words and end with a question asking if anyone has a conflict.”
The second prompt tells ChatGPT who it is, what to do, why, and what the result should look like. For more techniques, see prompt engineering basics.
Keep the conversation going
ChatGPT remembers everything in the current chat, so you rarely need to start over. Follow up with:
- “Make it shorter.”
- “Rewrite it in a more formal tone.”
- “Give me three alternative versions.”
- “What did you assume that might be wrong?”
Step 4: Upload files and photos
Click + and attach a PDF, Word document, spreadsheet, slide deck or image. Then ask questions about it. Useful examples:
- “Summarise this 40-page report in 10 bullet points for a busy manager.”
- “From this spreadsheet, which product had the biggest month-on-month growth? Show a chart.”
- “What does this error message in my screenshot mean and how do I fix it?”
- “Translate this menu photo and recommend a vegetarian dish.”
Free users have lower upload limits than paid users. Avoid uploading confidential documents to a personal account; read our AI safety basics first.
Step 5: Use web search for current information
ChatGPT can search the web and show sources. It usually decides on its own when a question needs fresh information, but you can force it by choosing Search from the tools menu or saying “search the web for…”. Always click a source or two to confirm important facts such as prices, laws or medical guidance.
For long, multi-source reports, try Deep Research. It spends several minutes reading many pages and returns a cited report. Free users get a small number of these each month; paid plans get more.
Step 6: Create and edit images
Ask ChatGPT to make an image in plain language: “Create a flat illustration of a cosy home office with plants, warm morning light, 16:9.” You can then ask for changes: “Make the desk white and add a cat.” You can also upload a photo and ask it to change the background or style.

Step 7: Talk to ChatGPT with voice
Tap the voice icon on mobile or desktop to have a spoken conversation. It is great for practising a language, rehearsing a presentation, brainstorming while walking or getting help while your hands are busy cooking.
Step 8: Organise work with Projects
Projects group related chats, files and instructions in one place. Create a project such as “Website redesign”, upload your brand guidelines and add instructions like “Always write in British English and keep a friendly, expert tone.” Every new chat in that project uses those files and rules automatically.
Step 9: Set custom instructions and memory
Go to Settings → Personalization. Here you can:
- Tell ChatGPT about yourself: your job, location, expertise level and interests.
- Set how it should respond: concise, no emojis, always include sources, and so on.
- Turn memory on or off. With memory on, ChatGPT can remember useful details across chats. You can view and delete memories at any time.
Step 10: Try custom GPTs and apps
Custom GPTs are versions of ChatGPT set up for a specific job, such as a writing coach, a travel planner or a spreadsheet helper. Browse them from the sidebar. ChatGPT can also connect to apps such as Google Drive, calendars and design tools so it can work with your data. Only connect accounts you trust and review what access you grant.

Common mistakes to avoid
- Trusting every answer. ChatGPT can be confidently wrong. Check facts, numbers and citations, especially for health, legal and money questions.
- Prompts that are too short. Add context and a desired format.
- Starting a new chat for every tweak. Follow-ups in the same chat are faster and better.
- Sharing sensitive data. Do not paste passwords, ID numbers or client secrets.
- Ignoring the “thinking” option. For maths, logic, planning and coding, a reasoning model gives noticeably better answers.
Free vs paid: do you need to upgrade?
Start free. Upgrade if you regularly hit message limits, need more file uploads or Deep Research, or want the strongest models and Codex for coding. ChatGPT Go is a cheaper middle option in many countries; Plus is the main paid plan. If you decide later it is not worth it, here is how to cancel a ChatGPT subscription. And if ChatGPT feels sluggish, see why ChatGPT is slow and how to fix it.
