How to use ChatGPT: a step-by-step beginner's guide

To use ChatGPT, go to chatgpt.com or install the official app, sign up with an email, Google, Microsoft or Apple account, and type your question. The basic service is free. Paid plans add higher usage limits and extra features.

This guide walks through each step, from creating an account to locking down your privacy settings. One caveat up front: ChatGPT's plans, model names and limits change every few months. Check OpenAI's official pages for current prices and caps before you decide anything.

How do I sign up for ChatGPT?

Open chatgpt.com in a browser. The old chat.openai.com address redirects there. Official apps exist for iOS, Android, macOS and Windows, and OpenAI links to all of them from its download page.

You can register with an email address or a Google, Microsoft or Apple account. Some sign-up flows also ask you to verify a phone number. Since 2024, many regions have also allowed limited use without an account at all, though availability varies by country and over time.

OpenAI's Terms of Use set a minimum age of 13. Users under 18 need permission from a parent or guardian. In 2025 OpenAI announced parental controls and age prediction, so check the terms page for the latest rules.

App stores are full of lookalike "ChatGPT" apps. Before installing, confirm that the developer is listed as OpenAI.

Is ChatGPT free? Free vs paid plans

Yes, there is a free plan. It gives capped access to OpenAI's flagship model, which was the GPT-5 family as of mid-to-late 2025. Once you hit the cap, chats fall back to a smaller model. Free users also get limited file uploads, image generation, voice, web search and custom GPTs.

Paid individual tiers include Go, a low-cost plan first launched in India in 2025 and later extended to other countries. Above it sit Plus and the top-end Pro plan. Organisations can choose Business (formerly Team), Enterprise or Edu.

We aren't listing prices here because they change often. They can also differ between the website and the Apple or Google app stores, and local taxes may apply on top. The official pricing page at openai.com/chatgpt/pricing and your checkout screen are the reliable references.

In early 2026 OpenAI announced it would test ads for Free and Go users, so what you see may depend on your plan and region. If you subscribed through Apple or Google, you must cancel in that store. Cancelling on the website won't work.

Can I use ChatGPT in other languages?

Yes. Write in Turkish, Spanish or most other major languages and ChatGPT will usually answer in the same one. You can change the interface language under Settings > General > Language, though menu labels shift with updates. Voice mode also handles multiple languages, including Turkish.

Be more careful with country-specific facts. Answers about local law, tax or government procedures can be out of date or simply invented. Check them against official government sources.

Tone is worth spelling out too. Saying "use formal address" or "keep it casual" makes a real difference in languages that distinguish between the two.

How do I write good ChatGPT prompts?

OpenAI's own guidance comes down to a few habits. Give context and a role, for example "You are a tutor explaining physics to teenagers." Then say what format and length you want: a bullet list, 200 words, a table.

Include an example of the output you're after if you can. Break large tasks into steps, asking for an outline first and then each section. If the first answer misses, refine it with follow-up messages rather than starting over.

For anything current, turn on web search and ask for sources. To avoid repeating your preferences in every chat, add them once in custom instructions under Settings > Personalization. Something like "Always answer briefly, in plain English" will then apply everywhere.

How do I change ChatGPT's privacy settings?

To stop your chats being used for training, open Settings > Data Controls and switch off "Improve the model for everyone." According to OpenAI's help pages, Business, Enterprise and API data are not used for training by default.

OpenAI says Temporary Chat conversations aren't saved to your history or used for training, but may be kept for up to 30 days for safety review. Its interaction with memory has changed in some updates, so check the help article. Memory itself can be viewed, edited or switched off under Settings > Personalization > Memory.

You can export your data and delete individual chats or your whole account. In 2025, a court order in the NYT v. OpenAI case temporarily required OpenAI to retain deleted chats, so look for OpenAI's latest statement on retention.

Whatever your settings, don't paste ID numbers, health records or client data. Be careful with shared links as well. In 2025, some shared chats became searchable on Google, and OpenAI removed the "discoverable" option in response.

What are the most common ChatGPT mistakes?

The biggest is trusting answers without checking them. ChatGPT can hallucinate facts and cite sources that don't exist, which is why the interface warns that it can make mistakes. A close second is assuming it knows recent news without turning on search.

Vague one-line prompts tend to produce generic answers. Pasting confidential information creates risks you can't undo. Unofficial sites promising "free GPT-5" and fake paid apps can cost you money or data.

Students should check their school's or university's AI policy before submitting AI-assisted work. Finally, don't treat ChatGPT as a medical, legal or financial authority. Use it as a starting point and take decisions with a qualified professional.
