Once registered, you'll be able to access the free version of ChatGPT. You may also see options to upgrade to a paid plan for access to more advanced models and features.

10 Practical Examples of Useful Prompts

A "prompt" is the instruction you give to ChatGPT. The quality of your prompt directly impacts the quality of the response. Here are 10 examples to get you started:

1. Email Writing: "Draft a professional email to my team of 5 people, informing them about a project deadline extension for 'Project Phoenix' to next Friday. Keep the tone positive and encouraging."

2. Idea Generation: "I'm starting a blog about sustainable living. Give me 10 creative and catchy blog post titles."

3. Learning: "Explain the concept of 'quantum computing' to me like I'm a high school student."

4. Trip Planning: "Create a 3-day itinerary for a trip to Tokyo, Japan, focusing on a mix of historical sites and modern culture. Include food recommendations."

5. Text Summarization: "Summarize the following article into five key bullet points: [paste article text here]."

6. Coding Help: "Write a Python function that takes a list of numbers and returns a new list with only the even numbers."

7. Creative Writing: "Write a short story opening about a detective who finds a mysterious clock that can stop time."

8. Resume Building: "Act as a career coach. Review my job description as a 'Project Manager' and help me write three impactful bullet points for my resume that highlight my achievements."

9. Social Media: "Generate three engaging Instagram captions for a photo of a mountain sunrise. Include relevant hashtags."

10. Role-playing: "I want to practice for a job interview. You are the interviewer for a 'Marketing Manager' role. Ask me three common interview questions."

Common Mistakes and How to Avoid Them

Vague Prompts: Instead of "write about cars," try "write a blog post comparing the pros and cons of electric vs. gasoline cars for a family of four." Be specific!
Not Providing Context: Tell the AI who you are and what you need. For example, "Acting as a financial advisor, explain the benefits of a Roth IRA."
Accepting the First Answer: Don't be afraid to ask for revisions. Use follow-up prompts like "Can you make this more concise?" or "Rewrite this in a more formal tone."
Factual Inaccuracies: While powerful, ChatGPT can sometimes provide incorrect information ("hallucinate"). Always double-check critical facts, especially for academic or professional work.
