Mastering Chatbots: ChatGPT, Gemini & DeepSeek

Mastering Chatbots is a short, practical course about the three chatbots most people will actually meet at work in 2026: OpenAI's ChatGPT, Google's Gemini, and the Chinese open-weight challenger DeepSeek. The course is built for two outcomes that usually get separated. First, theoretical fluency enough to hold your own in a meeting, a coffee chat, or a job interview when someone says "so, are you using AI?" Second, hands-on competence the patterns, prompts, and decision rules you'll actually reach for tomorrow morning.
