Getting Started with ChatGPT

What is ChatGPT?

ChatGPT is a conversational AI assistant built by OpenAI. It can answer questions, write text, summarize documents, write code, and much more — all through natural language. You don't need to learn any special commands; just type what you need.

Setting Up Your Account

1. Go to chat.openai.com and create a free account.
2. The free tier uses GPT-4o mini. For heavier use, GPT-4o is available on the Plus plan ($20/month).
3. On mobile, download the official ChatGPT app for iOS or Android.

Core Use Cases

Writing and Editing

Ask ChatGPT to draft emails, blog posts, or reports. Give it context about your audience and tone, and it will produce a solid first draft you can refine.

Example prompt:

"Write a professional email declining a meeting invitation. Keep it brief and friendly. I have a scheduling conflict on Thursday."

Summarizing Long Documents

Paste a long article, contract, or report and ask for a summary. You can also ask follow-up questions about specific sections.

Example prompt:

"Summarize the following research paper in plain English and list the three most important findings."

Coding Help

ChatGPT can generate, explain, debug, and refactor code in most popular languages.

Example prompt:

"Write a Python function that takes a list of numbers and returns only the even ones."

Brainstorming

Use it as a thinking partner. Ask for 10 ideas on a topic, then drill into the ones that interest you.

Tips for Better Results

• Be specific. "Write a headline for a blog post about AI tools aimed at small business owners" works far better than "write a headline."
• Set a role. Starting with "You are an expert in…" primes the model to respond with appropriate depth.
• Iterate. Your first prompt rarely produces the best result. Ask follow-up questions or request revisions.
• Provide examples. If you have a preferred style, paste a sample and say "write in this style."

Limitations to Keep in Mind

• ChatGPT can hallucinate — it may state incorrect facts confidently. Always verify claims for anything important.
• Its knowledge has a training cutoff date. For current events, use a model with web browsing enabled.
• It doesn't remember previous conversations by default (unless memory is enabled in settings).

Next Steps

Once you're comfortable with basic prompts, explore Custom Instructions (in Settings) to set a persistent context for all your conversations, and try GPTs — pre-configured assistants tuned for specific tasks like coding, cooking, or customer support.
