Re-AI Training Programme — Module 4 introduction Welcome to Module 4, Advanced AI Applications for Digital Work and Entrepreneurship. This is the final module of the Re-AI course. It sits at EQF level 4 to 5, which means the tasks are a step up from earlier modules. Plan for about 13 hours of learning in total. Do not worry. You already have the basic skills, and now you will put them to real work. So how does this module work? You will use AI at an advanced level, and you will make real things. There are four lessons, each about one and a half hours long. In lesson 4.1 you build and launch your own customer-service chatbot. In lesson 4.2 you use AI to analyse data, without being a data scientist. In lesson 4.3 you design an AI-powered business or freelance service. In lesson 4.4 you learn about AI ethics, bias and your legal duties under EU law. At the end, you finish with a capstone project, a final piece of work that shows what you can do. Here is what you will be able to do by the end. First, build a working chatbot. You will set up an AI assistant for customer service and test how well it performs. Second, turn data into insight. You will analyse a real dataset with AI tools and explain the results in plain language. Third, design an AI-powered service, with a six-month income plan and a short pitch deck. Fourth, work ethically and legally. You will check AI for bias and privacy risks, and meet your duties under the EU AI Act and the GDPR. Let's begin. Co-funded by the European Union.
