Prompt Engineering Essentials
Communicate clearly with AI to get useful, reliable results
Start this free courseThis practical, mobile-friendly course teaches you how to write clear, effective prompts for AI chat tools like ChatGPT, Gemini, and Claude. You will learn how large language models respond to instructions, how to structure prompts for study, work, and everyday tasks, and how to refine outputs safely and ethically. Designed for beginners, each short session builds a reusable skill you can apply immediately, even on a low-bandwidth phone.
What you'll learn
- Explain what a large language model is and how prompts shape its responses
- Apply core prompting components such as role, task, context, and format to build clear prompts
- Use iteration and refinement techniques to improve weak or vague AI outputs
- Design few-shot and step-by-step prompts for study, writing, and workplace tasks
- Evaluate AI responses for accuracy, bias, and hallucination before using them
- Practice responsible and ethical prompting including privacy and academic integrity

Sample lesson: How AI Chat Tools Understand You
A large language model (LLM) like ChatGPT is a prediction engine. It was trained on huge amounts of text and learned patterns of which words tend to follow other words. When you type a prompt, it does not "look up" a fixed answer. Instead, it predicts the most likely next word, then the next, building a response one p…
