Lessons

1. What AI chatbots really do (20 min). Most people start using ChatGPT or Gemini without knowing what happens inside. Five minutes of understanding saves you from the most common mistakes.
2. Your first great prompt (25 min). What you get back depends mostly on what you put in. A good prompt takes 30 seconds longer to write and saves you ten minutes of fixing.
3. Prompting in Sinhala, Tamil and English (20 min). You can talk to AI in your own language. Knowing when to use Sinhala, Tamil or English, and how to check a translation, gives you the best of both.
4. Is this answer right? Checking AI (25 min). In Microsoft’s 2026 survey, workers named checking AI’s output as the human skill that matters most as AI does more work. It is also the step most people skip.
5. Learn faster with AI, without fooling yourself (25 min). Students who let AI hand them answers score worse in exams later. Students who use AI to explain and quiz them learn more. The difference is how you ask.
6. AI for everyday work: the 3 As (25 min). Cocoon’s 3 As show where AI fits in any job or study. Most people should start with the first A, and do it well.
7. Make images, voice and video with AI (25 min). Canva, CapCut and Gemini put AI design and video in your pocket. Used well, they save hours. Used carelessly, they spread fakes.
8. Stay safe, stay honest (20 min). AI makes scams cheaper and more convincing. A few habits protect you, your family and your future job.
