This course provides a comprehensive and simplified introduction to the world of artificial intelligence, designed for non-technical learners to understand AI and begin using it safely and productively. It starts by exploring what AI is, the key terms encountered in common tools, and the strengths and limitations of large language models (LLMs). The course then moves from theory to practice through a simple, reusable prompting framework RTCCO (Role → Task → Context → Constraints → Output/Tone) with hands-on examples using ChatGPT, Copilot, and Gemini. Throughout the learning journey, you will gain quick guidelines for privacy protection, bias reduction, and safe data handling, building confidence in experimentation and iteration. The experience concludes with a guided mini-project that transforms a real-world task (such as writing an email, creating a summary, or preparing a brief) from an unclear initial request into a well-structured prompt and refined, ready-to-use output. By the end of the course, you will receive a ready-made prompt pack, checklists, and practical habits that save time in writing, summarizing, and brainstorming at work.
