What is ChatGPT?
ChatGPT is OpenAI's AI assistant that helps you write, analyze, code, and brainstorm. With GPT-4o, it handles text, images, and voice in a single conversation.
Getting Started
- Create an account at chat.openai.com
- Choose your plan: Free (GPT-4o mini) or Plus ($20/mo for GPT-4o, DALL-E, and more)
- Start chatting: Type your question or task in the message box
Prompt Engineering Basics
The quality of ChatGPT's responses depends on how you ask:
- Be specific: Instead of "write an email," say "write a professional follow-up email to a client about a delayed project, keeping a positive tone"
- Provide context: Tell ChatGPT your role, audience, and desired outcome
- Use examples: Show it what good output looks like
- Iterate: Refine your prompts based on the responses
