This course offers a practical and simplified introduction to understanding artificial intelligence, especially generative AI. You will learn the difference between traditional AI and generative AI, explore what large language models are, and then begin a step-by-step hands-on journey with ChatGPT: adjusting settings, understanding memory and how to manage it, and writing clear prompts using multiple strategies to reduce errors and hallucinations. You will also learn how to use alternative models such as Claude, Gemini, and DeepSeek, as well as Custom GPTs and productivity tools like Perplexity and Gamma. By the end of the course, you will have a practical plan for applying what you have learned to your daily tasks and using these tools to automate work and increase productivity with high quality.
